App Store & Google Play character counter
An App Store character counter checks your app name, subtitle, keyword field, promotional text and description, and your Google Play title and descriptions, against each store’s documented limits.

This counter counts characters the way a reader sees them, counts the App Store keyword field in bytes as Apple documents it, and flags wasted keyword space. It runs in your browser.
Store listing limits (checked October 31, 2026)
| Field | Limit | What the store says |
|---|---|---|
| App Store app name | 30 characters | At least two characters. Apple matches search text against the name, subtitle, keywords and primary category. |
| App Store subtitle | 30 characters | Shown under the name on the product page; one of the fields Apple matches for search. |
| App Store keywords | 100 bytes | Terms separated by commas with no spaces; each keyword longer than two characters; not shown on the product page. |
| App Store promotional text | 170 characters | Shown above the description and editable without a new submission; Apple says it does not affect search ranking. |
| App Store description | 4,000 characters | Plain text; not among the fields Apple lists for search matching. |
| Google Play app name | 30 characters | No emoji, emoticons or repeated special characters (Metadata policy). |
| Google Play short description | 80 characters | Google counts full-width and half-width characters equally. |
| Google Play full description | 4,000 characters | Google says store listing text helps users discover your app; avoid repetitive keywords. |
How the counter counts characters and emoji
Each field counts grapheme clusters: what a reader sees as one character. An accented letter typed as a letter plus a combining accent, an emoji with a skin tone, a flag and a family emoji joined with zero-width joiners each count as one.
Neither Apple nor Google documents how emoji count against a limit, and some systems count one emoji as two or more characters. When a field holds emoji or other combined characters the counter says so; leave a few characters of headroom and confirm in App Store Connect or Play Console before you publish. Google Play’s Metadata policy does not allow emoji in the app title at all, so the counter warns there.
The App Store keyword field checks
The keyword field is the one place where every byte is search metadata, so the counter also lists the waste Apple’s own guidance names. Each warning points at a word you can drop or replace.
- Spaces next to commas: Apple separates terms with commas and no spaces (spaces inside a phrase such as “white noise” are fine).
- Words repeated across terms: one copy is enough.
- Words already in your app name or subtitle: Apple already matches those fields.
- A plural of a word you already have, such as “sounds” next to “sound”: Apple treats the two as duplicates.
- Terms of two characters or fewer, and empty terms from double or trailing commas.
Use the space you free up
Brainstorm replacement terms with the keyword shuffle, then compare candidates in the keyword difficulty checker before you commit them. A word earns its place when real users type it and the apps ranking for it are within reach.
Frequently asked questions
What is the character limit for an App Store app name and subtitle?
Both are 30 characters, according to Apple’s App Store Connect Help (checked October 31, 2026). The name must also be at least two characters.
How long can the App Store keyword field be?
Apple’s App Store Connect Help gives 100 bytes. For plain English letters that is 100 characters; accented letters take 2 bytes and most other scripts 3, so the counter measures this field in bytes.
What are the Google Play character limits?
The app name is 30 characters, the short description 80 and the full description 4,000, according to Play Console Help (checked October 31, 2026). Google counts full-width and half-width characters equally.
How do emoji count toward the limit?
This counter counts each emoji as one character, as a reader sees it, including flags and joined family emoji. Neither store documents its own emoji counting and some systems count an emoji as two or more, so leave headroom. Google Play does not allow emoji in the app title.
Is my text sent to AppGazers?
No. The counter runs in your browser: what you type never leaves your browser and is not stored. It is free with no sign-in.
