Your App Store subtitle is 30 characters that sit directly below your app title in every search result, every browse page, and every time someone lands on your product page. It is one of the most visible pieces of text in your entire listing, and it is also a direct ranking signal for Apple's search algorithm.
Most indie developers either leave the subtitle blank, repeat words from their title, or stuff it with generic phrases like "The Best App." All three approaches waste one of the most valuable metadata fields in ASO.
This guide breaks down what the subtitle is, why it matters so much, and analyzes 15 real subtitles from top-performing apps to show you exactly what works and why. By the end, you will have a formula you can apply to your own app today.
What Is the App Store Subtitle
The subtitle is a 30-character text field available exclusively on iOS. You set it in App Store Connect when submitting a new version or updating your metadata. It appears in two high-visibility locations:
Search results: When a user searches for any term and your app appears in the results, the subtitle shows directly beneath your app title, right next to your icon. This is often the first piece of descriptive text a user reads about your app.
Product page: On your full listing page, the subtitle appears beneath the title at the top of the page, above the screenshots. It frames the user's first impression before they scroll to see anything else.
The subtitle is an iOS-only field. Google Play does not have an equivalent -- Android developers use the short description instead, which serves a similar purpose with a different character limit (80 characters). If you publish on both platforms, your subtitle strategy and short description strategy should be developed independently.
One important distinction: the subtitle is not the same as the promotional text field in App Store Connect. Promotional text can be updated without a new app version and is not indexed for search. The subtitle requires a version submission and is fully indexed by Apple's algorithm.
Why the Subtitle Matters for ASO
The subtitle punches far above its weight for three reasons:
It is a direct ranking signal. Apple indexes every word in your subtitle for search ranking purposes. A keyword in the subtitle has strong ranking impact -- not as powerful as the title, but significantly stronger than the keyword field. If you want to rank for a term and it does not fit in your title, the subtitle is the next best place for it.
It drives conversion. The subtitle appears in search results, which means it influences whether a user taps on your app or scrolls past it. A subtitle that clearly communicates what your app does and who it is for will generate more taps than a vague or empty one. Higher tap-through rates lead to more product page views, which lead to more downloads.
It compounds with other metadata. Apple combines words from your title, subtitle, and keyword field to match search queries. A keyword in your subtitle can combine with keywords in your title and keyword field to match multi-word searches you could never fit into a single field. For a deep dive into how Apple indexes and combines these fields, read our keyword research strategy guide.
These three factors make the subtitle one of the highest-ROI optimizations you can make on iOS. Changing 30 characters takes five minutes and can meaningfully impact both your visibility in search and your conversion rate from impression to download.
The Rules: What Apple Allows and Prohibits
Before writing your subtitle, understand the constraints Apple enforces:
30-character maximum. This is a hard limit. Not 31, not "about 30." Use our Character Counter to check your subtitle length before submitting. Every character counts, including spaces.
No generic terms. Apple's App Store Review Guidelines specifically prohibit generic descriptions of the app's quality or generic phrases. Terms like "The Best App," "Must-Have," or "#1 App" will likely get flagged during review.
No competitor names. Mentioning competitor brand names in your subtitle violates Apple's guidelines and can result in your update being rejected. It can also trigger legal complaints. Do not do it.
No pricing information. Do not include "Free," "On Sale," or specific prices in the subtitle. Apple handles pricing separately and does not allow it in metadata fields.
No calls to action. Phrases like "Download Now" or "Try Free Today" are not allowed. The subtitle should describe what the app does, not tell the user what to do.
Avoid repeating your title. While Apple does not technically prohibit this, it is a waste. Apple already indexes your title words. Repeating them in the subtitle burns characters that could target new keywords. If your title is "BudgetPal," do not make your subtitle "Budget Planning App." You already rank for "budget" from the title.
Within these constraints, you have significant creative freedom. The best subtitles use every one of those 30 characters to deliver a keyword-rich, benefit-driven phrase that tells the user exactly what they get.
15 Real Subtitle Examples by Category
Let us analyze real subtitles from top-performing apps across five categories. For each, we will break down why the subtitle works, which keywords it targets, and how efficiently it uses the 30-character limit.
Productivity
Notion: "Organize Life & Work" 20 characters. This subtitle nails the dual-audience positioning -- personal and professional -- in just three words. "Organize" is a high-volume keyword for productivity apps, and "Life & Work" broadens the target audience beyond just business users. The ampersand saves a character compared to "and." The only critique is that it leaves 10 characters unused, which could target an additional keyword.
Todoist: "Lists, Tasks & Plans" 20 characters. Three distinct keywords packed into a compact, scannable format. Each word targets a different search query: "lists" app, "tasks" app, "plans" app. The comma-separated structure reads like a quick feature summary. Users scanning search results immediately understand what the app does. Again, 10 characters left on the table, but the clarity is strong.
Asana: "Plan, Track & Manage" 20 characters. Three action verbs that describe the complete project management workflow. This subtitle targets users searching for planning tools, tracking tools, and management tools simultaneously. The verb-driven structure creates a sense of capability and action. The pattern here is worth noting: verb-based subtitles tend to convert well because they imply the user can do something immediately.
What works across all three: Every productivity subtitle leads with action words and avoids jargon. None of them waste characters on "App" or "Tool" or "The Best." They let the verbs and nouns do the work.
Finance
Revolut: "Mobile Banking Made Easy" 23 characters. This subtitle does two things at once. It targets the high-volume "mobile banking" search query while adding a benefit qualifier ("Made Easy") that addresses the primary concern of fintech users: complexity. The phrase "made easy" is a proven conversion driver across categories because it reduces perceived effort.
Mint: "Budget & Bill Tracker" 21 characters. Two keywords packed into a clean, readable phrase. "Budget" and "bill tracker" are both high-volume search terms for personal finance apps. The subtitle positions Mint as covering two distinct use cases -- budgeting and bill management -- which expands the audience. The ampersand again saves space.
Venmo: "Send & Receive Money" 20 characters. Purely functional and instantly clear. A user who has never heard of Venmo immediately understands its purpose from this subtitle alone. "Send money" and "receive money" are both active search queries. The simplicity is the strength -- there is no ambiguity about what this app does.
What works across all three: Finance subtitles tend to be literal and functional. Users searching for financial tools want clarity, not creativity. These subtitles tell you exactly what the app does in the most direct language possible.
Health and Fitness
Strava: "Activity & Health Tracker" 25 characters. This subtitle casts a wide net. "Activity tracker" captures runners, cyclists, hikers, and swimmers. "Health tracker" captures a broader fitness-curious audience. At 25 characters, it uses the space efficiently without feeling cramped. The word "tracker" does heavy lifting since it is one of the most common search modifiers in the health category.
Nike Training Club: "Workout & Fitness Plans" 23 characters. Two of the highest-volume search terms in the fitness category -- "workout" and "fitness plans" -- combined in a single subtitle. "Plans" implies structured content rather than random exercises, which signals value to users who want guided programs. This subtitle targets users at the research stage who are searching for workout programs.
Calm: "Sleep & Meditation" 18 characters. Remarkably short, but every word is a high-volume keyword. "Sleep" and "meditation" are both standalone search categories with millions of monthly queries. Calm could have added more -- they have 12 unused characters -- but the minimalism matches their brand identity. Sometimes brevity reinforces the product positioning.
What works across all three: Health subtitles rely heavily on category-defining keywords. Terms like "tracker," "workout," "sleep," and "meditation" are what users actually type into the App Store. These subtitles mirror the user's search language rather than inventing marketing speak.
Social and Messaging
Instagram: "Photos & Videos" 15 characters. Half the available space, but arguably the most effective subtitle in the entire App Store. It tells you exactly what the platform is about using the two keywords that define its content type. Every person searching for a "photos" or "videos" app will see Instagram match their query. The extreme simplicity works because the brand is already well-known.
TikTok: "Make Your Day" 13 characters. This is the exception to the "use keywords" rule. TikTok is so dominant in its category that it does not need keyword-driven subtitles. Instead, it uses an emotional, benefit-driven phrase that reinforces the brand promise. For indie developers, this approach is risky -- you do not have TikTok's brand recognition to compensate for the lack of keywords. Do not copy this strategy unless you are already the category leader.
WhatsApp: "Messages & Video Calls" 22 characters. Two core features, two high-volume search terms. "Messages" targets users searching for messaging apps, while "video calls" targets the growing video communication market. This subtitle does exactly what a good subtitle should: describe what you get when you download the app.
What works across social: The established players keep it simple and descriptive. Note that even massive brands like Instagram and WhatsApp use keyword-rich subtitles rather than clever taglines. The only outlier is TikTok, and they can afford to prioritize branding because their search volume comes from brand queries.
Games
Clash of Clans: "Build & Battle Online" 21 characters. Two action verbs that capture the two core gameplay loops -- building bases and battling opponents. "Online" signals multiplayer, which is a key differentiator and search modifier for mobile games. This subtitle targets users searching for "build games" and "battle games" while communicating that the experience is multiplayer.
Words With Friends 2: "Word Board Game" 15 characters. Direct, functional, and packed with the category keyword "word board game." For a game with strong brand recognition, this subtitle serves purely as a keyword play, ensuring the app appears in searches for board game and word game combinations.
Subway Surfers: "Run, Jump & Dash" 16 characters. Three action verbs that physically describe the gameplay. A user who has never seen Subway Surfers can read "Run, Jump & Dash" and immediately understand the genre. Each verb also targets search queries: "running games," "jumping games," and "dash games." The comma-separated structure mirrors the Todoist and Asana patterns from the productivity category.
What works across games: Game subtitles use action verbs that describe core mechanics. This serves double duty -- it helps users understand the gameplay and targets mechanical keywords that gamers search for. Unlike other categories, games lean into verbs rather than nouns.
Common Subtitle Mistakes
After analyzing hundreds of app subtitles, these are the patterns that consistently underperform:
Repeating Title Words
If your title is "FocusTimer - Pomodoro Timer," do not set your subtitle to "Focus Timer for Productivity." You already rank for "focus" and "timer" from the title. The subtitle should introduce new keywords like "Study Planner & Tracker" to expand your keyword coverage. Every repeated word is a wasted opportunity to rank for an additional search query.
Using "The Best App For..."
This wastes 18 characters on filler before you even get to the useful part. "The Best App For" contains zero indexable keywords that would help you rank, violates Apple's guidelines about generic quality claims, and reads as empty marketing. Replace it with specifics: what does the app actually do?
Leaving It Blank
A surprising number of apps have no subtitle at all. This is leaving free ranking signals on the table. Even a mediocre subtitle is better than no subtitle, because at minimum it gives Apple additional keywords to index for your app.
Keyword Stuffing Without Readability
"Budget Money Finance Track Save" hits multiple keywords but reads like a broken sentence. Remember, users see this text in search results. If it looks like spam, it will hurt your tap-through rate even if it helps your rankings slightly. The net effect is usually negative.
Including "App" or "Application"
Apple already categorizes your listing as an app. Using "app" in your subtitle wastes 3-4 characters on a word that adds no ranking value and no user value. Strip it out and replace it with a keyword or benefit that actually differentiates you.
The Subtitle Optimization Formula
Based on the patterns from the top-performing apps analyzed above, the most effective subtitle formula is:
[Action Verb] + [Core Benefit] + [Secondary Keyword]
Here is how to apply it:
-
Choose your action verb. Pick a verb that describes what the user does with your app: Track, Plan, Build, Create, Manage, Learn, Find, Record, Monitor, Edit. Verbs establish agency and make the subtitle feel active rather than passive.
-
Add your core benefit. What is the primary value proposition? This should be the single most important thing your app delivers: workouts, budgets, photos, tasks, sleep, recipes. Use the noun that matches what users search for.
-
Include a secondary keyword. If you have characters remaining, add a second keyword connected with "&" or a comma. This second term should target a related but different search query than your title and primary benefit.
Formula in action:
- Fitness app: "Track Workouts & Nutrition" (26 chars)
- Note-taking app: "Write, Organize & Share" (23 chars)
- Weather app: "Forecasts & Storm Alerts" (24 chars)
- Meditation app: "Relax, Focus & Sleep Better" (27 chars)
- Recipe app: "Cook, Plan & Eat Healthy" (24 chars)
Each example uses the full formula, stays under 30 characters, and includes at least two indexable keywords that do not overlap with a typical title.
To check your character count precisely, use our Character Counter tool -- paste in your subtitle and you will immediately see whether you are within the 30-character limit.
How to A/B Test Your Subtitle
Writing a good subtitle is step one. Testing it is step two. Apple provides a built-in mechanism for this: Custom Product Pages.
What Custom Product Pages Allow
You can create up to 35 custom product pages for your app, each with its own subtitle, screenshots, and promotional text. Each custom product page gets a unique URL that you can use in marketing campaigns, ads, or targeted links.
While Custom Product Pages are primarily designed for paid acquisition campaigns, you can use them to test different subtitle variations by driving traffic to each page and measuring the conversion rate.
Setting Up a Subtitle Test
- In App Store Connect, go to your app and select "Custom Product Pages"
- Create a new custom product page with a different subtitle variation
- Keep all other elements (screenshots, description, icon) identical so the subtitle is the only variable
- Drive equal traffic to both your default page and the custom page using separate campaign links
- After sufficient traffic (at least 1,000 impressions per variation), compare the conversion rates
What to Test
Run tests that isolate specific variables:
- Keywords vs. benefits: "Track Runs & Cycling" vs. "Get Fit & Stay Active"
- Specific vs. broad: "Vegan Meal Planner" vs. "Healthy Recipes & Plans"
- Feature-focused vs. outcome-focused: "Photo Editor & Filters" vs. "Make Photos Beautiful"
The winning subtitle is the one that produces the highest conversion rate from impression to download. A 1-2% improvement in conversion, applied to all your organic search impressions, compounds into significant download gains over months.
Product Page Optimization (PPO)
Apple also offers Product Page Optimization, which runs native A/B tests on your default product page. PPO allows you to test different icons, screenshots, and app previews -- but not subtitles directly. However, by combining PPO for visual elements with Custom Product Page tests for subtitle variations, you can systematically optimize every element of your listing.
Putting It All Together
Your subtitle is 30 characters that appear in every search result and on your product page. It directly impacts both your search ranking and your conversion rate. The top apps across every category use it to pack in keywords and communicate clear benefits -- not for taglines, not for brand slogans, and definitely not left blank.
Here is your action plan:
- Audit your current subtitle. Does it repeat words from your title? Does it include "app" or generic phrases? If so, rewrite it.
- Research competitor subtitles in your category. What keywords are the top 10 apps targeting? Which terms are you missing?
- Apply the formula: [Action Verb] + [Core Benefit] + [Secondary Keyword]. Check it against the 30-character limit.
- Run keyword research to validate your chosen terms. Our guide on ASO keyword research walks through the full process, and understanding how to maximize your iOS keyword field will ensure your subtitle works in harmony with your other metadata.
- Submit the update and monitor your search rankings and conversion rate for the following 2-4 weeks.
Thirty characters. No filler. Every word earns its place. That is how the best apps in the world approach their subtitles, and it is how you should approach yours.
