How to Check if Your App Name is Available (And Why It Matters for ASO)

Choosing an app name feels like a creative exercise. It is not. It is a strategic decision that directly affects whether users find your app, remember it, and trust it enough to download. The name you pick determines your first impression in search results, your ability to rank for relevant keywords, and your long-term brand equity in an ecosystem with over 4 million apps.

And yet, most indie developers pick a name they like, search for it once on the App Store, and call it done. That approach leads to one of three problems: your name is already taken, your name is too generic to rank for, or your name creates a trademark conflict that forces a rebrand six months later.

This guide covers every method for checking app name availability, what to do when your first choice is taken, and how to pick a name that works for both branding and App Store Optimization. If you want to check availability right now without reading the full guide, our free App Name Checker scans both stores instantly.

Why Your App Name Matters More Than You Think

Your app name is not just a label. It is the single most powerful ranking signal in both Apple's and Google's search algorithms. Keywords placed in your app title carry more weight than keywords in any other metadata field -- more than the subtitle, the keyword field, or the description.

On top of ranking power, the name is the first thing users see in search results. Before they see your icon, before they read your subtitle, before they look at screenshots -- they see your name. A confusing, generic, or overly long name creates friction. A clear, memorable name creates trust.

Both platforms enforce a 30-character limit on app titles. That constraint is not negotiable, and it means every character counts. You need to fit your brand name, ideally a primary keyword, and enough context for users to understand what your app does -- all within 30 characters. If you are not sure whether your planned title fits, run it through our Character Counter before committing.

The name also defines your brand presence beyond the store. It is what users type when recommending your app to friends. It is what shows up on the home screen. It is what reviewers and journalists use in articles. A weak name undermines all of these touchpoints regardless of how good your app actually is.

Where to Check App Name Availability

Checking app name availability is not a single-step process. An available name on the App Store might still be taken on Google Play, registered as a trademark, or squatted as a domain. Here is every place you should check, in order of priority.

1. App Store Search (iOS)

Open the App Store on your iPhone or go to the web version at apps.apple.com. Search for your exact intended name. Then search for close variations -- singular versus plural, with and without spaces, with common modifiers like "app" or "pro."

What to look for:

• Exact matches: If an app already exists with your exact name, you have a problem. Even if it is in a different category, users searching for your name will find that app instead.
• Close matches: If there are three apps with similar names (like "Spark," "SparkNote," "SparkApp"), the search space is already crowded and you will struggle to own that keyword.
• Category overlap: A name collision with an app in a completely different category is less problematic than one in your same category.

Manual App Store search is slow but definitive. It shows you exactly what users will see when they search for your name.

2. Google Play Search (Android)

Repeat the same process on Google Play at play.google.com. The two stores have completely different app catalogs, and a name that is available on iOS might be taken on Android.

Google Play search works differently from Apple's. Google indexes the full description text, which means more apps can appear for any given keyword. A name search on Google Play will often return more results, including apps that mention your name in their description but do not use it as their title.

If you plan to launch on both platforms -- and most indie developers should -- you need your name to be available on both.

3. Apple Developer Account (App Store Connect)

This is the only truly definitive check for iOS. Apple allows developers to reserve app names through App Store Connect. If someone has reserved a name, no other developer can use that exact name on the App Store -- even if the app has not launched yet.

To check, log into App Store Connect, go to My Apps, click the plus button to create a new app, and enter your intended name. If Apple accepts it, the name is available and is now reserved for you. If it rejects it, the name is taken.

Important: reserving a name is a commitment. Apple expects you to submit an app within 180 days. If you do not, the reservation expires. Do not reserve names speculatively unless you are genuinely planning to use them.

4. Google Play Console

Google Play handles naming differently. There is no formal name reservation system. You can only claim a name by actually publishing an app (or creating a draft listing) in the Google Play Console. This means that unlike iOS, you cannot definitively check availability without starting the publishing process.

However, the Google Play search method above gives you a practical answer. If no existing app uses your exact name as its title, you are likely clear.

5. Domain Availability

Your app name should ideally match an available domain. Even if you do not plan to build a website immediately, securing the domain protects your brand and gives you a landing page option for the future.

Check domain availability on registrars like Namecheap or GoDaddy. Look for .com first, then .app (a domain extension made for apps), then your country-code TLD.

If the .com is taken but the .app is available, that is usually acceptable for a mobile-first product. If both are taken, consider whether the existing domain owner is in a related space. If they are, the name collision will cause confusion beyond the app stores.

6. Social Media Handles

Check Twitter/X, Instagram, and any other platforms relevant to your marketing strategy. Inconsistent handles across platforms create confusion and make it harder for users to find you.

Use a service like Namechk or Knowem to check handle availability across dozens of platforms simultaneously. Even if you do not plan to use every platform, securing consistent handles early prevents someone else from claiming them later.

7. Trademark Databases

This is the step most indie developers skip, and it is the one that can cause the most expensive problems. If another company holds a trademark on a name similar to yours in a related product category, they can send you a cease-and-desist letter, force you to rebrand, and in extreme cases, get your app removed from the stores.

Check these databases:

• USPTO (United States Patent and Trademark Office) at tess2.uspto.gov -- covers US trademarks.
• EUIPO (European Union Intellectual Property Office) at euipo.europa.eu -- covers EU trademarks.
• WIPO Global Brand Database at branddb.wipo.int -- covers international trademarks.

Search for your exact name and close variations. Pay attention to the "Nice Classification" -- trademarks are registered for specific categories of goods and services. Class 9 covers software and mobile applications, and Class 42 covers SaaS. If someone has a trademark in one of those classes with a name similar to yours, consult a trademark attorney before proceeding.

8. Use Our Free App Name Checker

If the manual process above sounds tedious -- and it is -- our App Name Checker automates the most time-consuming parts. Enter your intended name and it checks availability across both the App Store and Google Play instantly, showing you which apps already use that name and how crowded the search space is.

It will not check trademarks or domains for you (those require separate searches), but it handles the store availability checks in seconds instead of minutes.

What to Do If Your Name Is Taken

Your first-choice name will often be taken. With over 2 million apps on the App Store and over 3 million on Google Play, simple, descriptive names were claimed years ago. Here is how to pivot without settling for a bad name.

Add a Qualifier

The most common strategy is appending a descriptive qualifier to a short brand name. This preserves the brand while adding keyword value for ASO.

Examples of this pattern in practice:

• "Spark" is taken. "Spark - Habit Tracker" gives you a unique identity plus a keyword.
• "Focus" is taken. "Focus Flow - Pomodoro Timer" differentiates and adds search terms.
• "Pulse" is taken. "Pulse - Heart Rate Monitor" clarifies the function and targets a keyword.

The separator matters. A dash - is the most common and cleanest. A colon : works but looks slightly more formal. Avoid using pipes |, slashes /, or multiple separators.

Coin a New Word

Some of the most recognizable app brands are invented words: Spotify, Zillow, Shazam, Venmo. Coined words are almost always available across stores, domains, and social media -- and they are inherently brandable because no one else is using them.

Techniques for coining words:

• Blend two words: "Pin" + "Interest" = Pinterest. "Snap" + "Chat" = Snapchat.
• Modify a real word: "Calm" becomes "Calmy." "Track" becomes "Trakr."
• Use a different language: Latin, Greek, or Japanese roots can produce unique, phonetically pleasing names.
• Invent from phonetics: Choose syllable combinations that feel right. "Zumo," "Vello," "Nimbo" -- none of these mean anything, but they sound like real products.

The trade-off is discoverability. A coined word has zero inherent search volume. Nobody searches for "Shazam" until they already know the app. You will need to pair a coined name with a strong subtitle and keyword strategy to compensate.

Target a Different Angle

Sometimes the problem is not that your name is taken, but that you are targeting the same angle as everyone else. If there are already five apps named "Sleep Tracker" or "Budget App," the solution is not to be "Sleep Tracker Pro" -- it is to approach the concept from a different direction.

Instead of "Sleep Tracker," consider "DreamLog," "Restful," or "Pillow" (which is an actual app that took exactly this approach). Instead of "Budget App," try "Pennywise," "Cashflow," or "Spendless."

A distinctive angle in your name helps you stand out in search results even when competing against established apps. When every result says "Budget Tracker" and yours says "Cashflow - Smart Money Manager," users notice the difference.

App Name Best Practices for ASO

A good app name satisfies three requirements simultaneously: it ranks well in search, it communicates your app's purpose, and it is memorable enough to build a brand around. Here is how to optimize for all three.

Include Your Primary Keyword

The most impactful ASO move you can make is putting your most important keyword in your title. If your app helps people track habits, the word "habit" or "habits" should appear in your title. If it is a photo editor, "photo" or "editor" should be there.

This is not about keyword stuffing. It is about aligning what you call your app with what users actually search for. Apple and Google both give heavy ranking weight to title keywords, and ignoring that signal is leaving free discoverability on the table.

Use the Brand + Keyword Pattern

The most effective naming pattern on both stores follows this structure: Brand Name - Keyword Phrase. Look at how top-performing apps do it:

• "Headspace: Meditation & Sleep"
• "Duolingo - Language Lessons"
• "Notion - Notes, Tasks, AI"

The brand name occupies the first position (what users remember), and the keyword phrase occupies the rest (what the algorithm indexes). The separator -- a dash, colon, or nothing -- keeps them visually distinct.

This pattern works because it serves both masters. The brand name builds recognition over time, and the keyword phrase ensures discoverability from day one. New apps need the keyword portion more; established apps can lean more on the brand.

Keep It Pronounceable and Memorable

A name that users cannot pronounce is a name they cannot recommend to friends. Word-of-mouth is still the most powerful growth channel for apps, and it requires a name that works in conversation.

Test your name by saying it out loud. "Hey, have you tried [your app name]?" If it sounds natural, good. If you have to spell it out, explain the capitalization, or clarify the pronunciation, reconsider.

Avoid:

• Random capitalization: "myAppName" is harder to communicate than "My App Name."
• Numbers substituted for letters: "Tr4cker" is clever in a URL, confusing everywhere else.
• Abbreviations that require explanation: "HTBK" means nothing unless you already know the app.

Avoid Special Characters

Both Apple and Google's search algorithms have limitations with special characters. Accented letters, emojis, and unusual Unicode characters can cause indexing issues. Some characters are simply ignored by the search algorithm, which means they take up character space without contributing to discoverability.

Stick to standard ASCII letters, numbers, and common separators (dashes, colons). If your brand naturally includes an accented character (common in Spanish, French, and other languages), test whether the store indexes it correctly by searching for both the accented and unaccented versions.

Real Examples of Great App Names (And Why They Work)

Theory is useful. Examples are better. Here are real app names that demonstrate strong ASO naming principles, broken down by what makes each one effective.

"Headspace: Meditation & Sleep"

• Brand: "Headspace" -- memorable, evocative of the mental space the app creates.
• Keywords: "Meditation" and "Sleep" -- two high-volume search terms.
• Separator: Colon, which reads naturally.
• Character count: 32 characters (slightly over the limit in some locales, but Headspace has the authority to push this).
• Why it works: The brand is strong enough to stand alone, but the keyword tail captures users who search for "meditation app" or "sleep app."

"Duolingo - Language Lessons"

• Brand: "Duolingo" -- coined word, highly distinctive.
• Keywords: "Language Lessons" -- the exact phrase most people search when looking for a language learning app.
• Character count: 28 characters. Fits perfectly.
• Why it works: A coined brand that has no competition for its name, combined with the highest-value keyword phrase in its category.

"Notion - Notes, Tasks, AI"

• Brand: "Notion" -- real word, but distinctive enough in context.
• Keywords: Three separate keywords -- "Notes," "Tasks," and "AI" -- each targeting a different search query.
• Character count: 25 characters. Room to spare.
• Why it works: Maximizes keyword coverage by listing multiple functions instead of one. A user searching for "notes app," "task manager," or "AI notes" can all find Notion.

"Spark Mail - Email by Readdle"

• Brand: "Spark Mail" -- brand plus category keyword.
• Keywords: "Email" -- the core keyword reinforced twice. "Readdle" -- the developer brand for users who know and trust them.
• Character count: 28 characters.
• Why it works: Double-reinforces the core keyword while attributing to a trusted developer brand. Users who search "email app" see the keyword twice.

"VSCO: Photo & Video Editor"

• Brand: "VSCO" -- short, distinctive abbreviation.
• Keywords: "Photo," "Video," "Editor" -- three high-volume terms.
• Character count: 27 characters.
• Why it works: The abbreviation is short enough to leave room for three separate keywords, each of which matches different search queries.

"Bear - Markdown Notes"

• Brand: "Bear" -- short, memorable, distinctive.
• Keywords: "Markdown Notes" -- a niche keyword phrase that targets a specific audience.
• Character count: 22 characters.
• Why it works: Instead of competing for the generic "notes app" term, Bear targets a more specific niche. Users searching for "markdown notes" have a very specific intent, and Bear matches it precisely.

"Todoist: To-Do List & Planner"

• Brand: "Todoist" -- coined word combining "to-do" and "-ist."
• Keywords: "To-Do List" and "Planner" -- two distinct keyword phrases.
• Character count: 30 characters. Exactly at the limit.
• Why it works: Uses every available character. The coined brand is self-explanatory (you can guess what Todoist does from the name alone), and the keyword tail covers both task management and planning queries.

"Fantastical - Calendar & Tasks"

• Brand: "Fantastical" -- play on "fantastic" plus "calendar."
• Keywords: "Calendar" and "Tasks" -- the two primary search terms for productivity scheduling apps.
• Character count: 30 characters. Perfectly optimized.
• Why it works: The brand name itself hints at the app's purpose (calendar) while sounding premium. The keyword tail is straightforward and covers the main search queries.

Common App Naming Mistakes

Naming mistakes are expensive because they compound over time. A bad name does not just cost you downloads today -- it costs you every day until you fix it, and fixing it means losing whatever brand recognition you have built. Here are the mistakes that cause the most damage.

Using a Generic Name

Naming your app "Photo Editor" or "Weather App" seems logical -- those are exactly what users search for. But generic names are nearly impossible to rank for because you are competing against every app with the same name, plus every app that uses those words in its title.

Search for "photo editor" on the App Store. You will find dozens of apps with nearly identical names. Users have no way to distinguish yours from the rest, and Apple's algorithm has no reason to rank a new, unproven app above established ones with millions of downloads and thousands of reviews.

A generic name also makes word-of-mouth impossible. "Hey, download Photo Editor." "Which one?" "The one with the blue icon." This is not how growth works.

Choosing a Name Too Similar to a Competitor

If the top app in your category is called "FitTrack," naming yours "FitTrak" or "FitTracker" is a liability, not an advantage. You might catch some of their search traffic initially, but you also risk:

• Trademark claims: The established app can file a trademark complaint with Apple or Google, potentially getting your app removed.
• User confusion: Users looking for the competitor might download your app by mistake, leave a bad review when it is not what they expected, and tank your ratings.
• Brand weakness: You will always be seen as a knockoff rather than an original product.

Ignoring Character Limits

Both iOS and Android enforce a 30-character title limit. If your intended name is 35 characters, something gets cut. The store will truncate it, and you lose control of what users see.

Worse, some developers do not realize that the separator and spaces count toward the limit. "MyApp - The Ultimate Budget Tracker" is 38 characters. After truncation, it might display as "MyApp - The Ultimate Budge..." which looks broken and unprofessional.

Always count characters before committing to a name. Our Character Counter shows you exactly how your name fits within iOS and Android limits.

Using Special Characters or Accents

As mentioned above, special characters can cause search indexing problems. But the bigger issue is practical: users cannot easily type special characters on a phone keyboard. If your name is "Cafe" but stylized as "Cafe" with an accent, users searching without the accent might not find you.

The same applies to emojis in app names (yes, some developers try this). Most store search algorithms either ignore emojis or handle them inconsistently. They waste precious characters and add no search value.

When to Change Your App Name

Sometimes the right move is renaming your app. A rebrand is a significant decision, but there are situations where the cost of keeping a bad name exceeds the cost of changing it.

When a Rebrand Makes Sense

• Your name creates trademark conflicts. If you have received a cease-and-desist or a complaint through the app store, renaming is not optional -- it is urgent.
• Your name is too generic to rank. If you are on page 5 of search results for your own name, the name is working against you. A more distinctive name with a keyword qualifier could improve your ranking dramatically.
• You are expanding to a new market. A name that works in English might be unpronounceable, offensive, or meaningless in other languages. Research this thoroughly using our guide on cross-localization strategy.
• Your app's focus has shifted. If you launched as a "meditation timer" but your app now includes journaling, breathing exercises, and sleep sounds, a name that only references meditation limits your keyword reach.

Impact on Existing Rankings

Changing your app name will temporarily disrupt your search rankings. Any keywords in your old title that are not in your new title will lose their ranking boost. Users who search for your old name will not find your app unless you keep the old name as a keyword.

The disruption is temporary. Within one to two update cycles (typically 1-3 weeks on iOS), Apple re-indexes your new metadata and your rankings stabilize around the new keywords. If your new name is better optimized, the new rankings will eventually surpass the old ones.

How to Rebrand Safely

1. Add old name keywords to your keyword field. If your old title was "MediTimer - Meditation Timer" and your new title is "Serenity - Mindfulness & Sleep," add meditimer,meditation,timer to your iOS keyword field to maintain some ranking for those terms.
2. Update your subtitle to bridge the transition. Your subtitle can reference what the app was previously known as or include keywords from the old name.
3. Update all visual assets. Screenshots, icons, and promotional images should reflect the new brand. Inconsistency between name and visuals looks like a mistake, not a rebrand.
4. Announce the change. Use your app's update notes, social media, and website to explain the rebrand. Users who know your old name need to know the new one.
5. Monitor rankings weekly. Track your keyword positions for both old and new keywords for at least a month after the change. Our keyword research strategy guide covers how to set up systematic keyword monitoring.

Putting It All Together

Choosing an app name is one of the few decisions that affects everything -- your search rankings, your brand identity, your legal exposure, and your ability to grow through word-of-mouth. It deserves more than five minutes of brainstorming.

Here is the process in summary:

1. Brainstorm 10-15 name candidates that follow the Brand + Keyword pattern.
2. Check each candidate across both app stores, domains, social media, and trademark databases. Use our App Name Checker to speed up the store checks.
3. Verify character counts with the Character Counter to ensure each candidate fits within the 30-character title limit.
4. Evaluate the competitive landscape for each surviving name. How many apps already use similar names? How strong are they?
5. Choose the name that best balances brand distinctiveness, keyword value, and availability.
6. Reserve it immediately in App Store Connect if you are targeting iOS.

For a broader understanding of how your name fits into your overall optimization strategy, read our complete ASO guide. If you are still in the pre-launch phase, our guide on pre-launch ASO walks through the full timeline from keyword research to launch day. And once your name is set, make sure your iOS keyword field complements it by targeting keywords your title does not cover.

Your app name is permanent -- or at least, changing it is costly. Get it right from the start.
