App Store Character Counter
Write your app store metadata with live character counts. Platform-specific limits for iOS and Android — so you never exceed the limit.
💡 Include your most important keyword naturally. This is the most heavily weighted ASO field.
💡 iOS subtitle: 30 chars. Android short description: 80 chars. Use this to complement your title with secondary keywords.
💡 Comma-separated, no spaces after commas. Don't repeat words from your app name. Android indexes the full description instead.
💡 Can be updated without a new app review. Great for seasonal promotions and feature announcements.
💡 iOS does NOT index this for search — write it for humans. Android DOES index it — include keywords naturally throughout.

What This Tool Does
This tool tracks your app name, subtitle, keyword field, promotional text, and full description against the exact character limits enforced by Apple and Google, with a live count and a progress bar for each field. It is built for indie developers and small teams filling out App Store Connect or Google Play Console who don't want to find out a field got truncated only after it was already live.
Switch between iOS and Android with the toggle above. Fields that don't exist on the selected platform, like the iOS keyword field on Android, are grayed out so you always know which limits actually apply to what you're writing.
iOS vs. Android Character Limits
| Field | iOS (App Store) | Android (Google Play) |
|---|---|---|
| App Name / Title | 30 characters | 30 characters |
| Subtitle / Short Description | 30 characters (subtitle) | 80 characters (short description) |
| Keyword Field | 100 characters, comma-separated | Not available (no equivalent field) |
| Promotional Text | 170 characters (editable without a new review) | Not available |
| Full Description | 4,000 characters | 4,000 characters |
How It Works
Pick your platform
Toggle between iOS and Android at the top so you only see the limits that apply.
Type or paste each field
Work through app name, subtitle, keyword field, promotional text, and full description one at a time.
Watch the live count
Each field shows a running character count, a colored progress bar, and a warning once you pass 85 percent of the limit.
Fix anything over the limit
Fields that exceed the limit turn red. Trim the text before you paste it into App Store Connect or Play Console, since both platforms will otherwise truncate or reject it.
Frequently Asked Questions
What is the App Store app name character limit?+
Apple allows up to 30 characters for the app name shown on the App Store. This is one of the most heavily weighted fields for App Store search, so it is worth using every character on your most important keyword.
What is the subtitle character limit on iOS?+
The App Store subtitle field allows up to 30 characters and is indexed for search alongside your app name and keyword field, so it is worth filling completely rather than leaving it short.
Does Google Play have the same limits as the App Store?+
No. Google Play uses a 30-character title and an 80-character short description, and it has no equivalent to Apple's hidden 100-character keyword field or 170-character promotional text. The 4,000-character full description limit is the same on both platforms.
What happens if I exceed a character limit?+
App Store Connect and Google Play Console will either block submission or truncate the text automatically, which usually cuts a sentence off mid-word in store search results. Check every field here before you paste it into either console.
Common Mistakes
Leaving characters unused in the keyword field
The 100-character iOS keyword field is hidden from users, so there is no conversion cost to filling it completely. Unused characters are wasted ranking potential.
Exceeding the subtitle limit and getting truncated
Writing a subtitle longer than 30 characters on iOS gets cut off in search results and on the product page, often mid-word, which looks unpolished and can hide your secondary keyword entirely.
Repeating your app name in the keyword field
Apple already indexes your app name separately, so reusing those same words in the 100-character keyword field wastes space that could target new terms.
Assuming Android has a hidden keyword field
Google Play has no equivalent to Apple's keyword field. On Android, your ranking depends on the visible title, short description, and full description text instead, so keywords need to live in the copy itself.
