Free tool App Store and Google Play text checker
Write your store listing once and see, field by field, whether it fits every store you publish to. Each store counts differently: App Store keywords are measured in UTF-8 bytes, vivo and WeChat count a Chinese character as two, and Huawei’s one-line intro allows 17 characters in Chinese but 80 in other languages. Every limit here comes from the store’s own documentation, with the source one click away.

Choose the stores you publish to, then edit the fields. Under each field you see the count and the limit for every selected store; hover a tag for the official wording.
Stores
Some limits depend on it: Huawei’s one-line intro is 17 characters in Chinese, 80 in other languages.
Huawei’s release notes allow 500 characters for mainland China and 1,000 elsewhere.

Checks
- NoteSpaces next to commas use 1 bytes of the 100. Apple: separate terms with commas and no spaces.
- CheckRepeated keywords: budget. Each repeat wastes bytes.
- NoteAlready in the name or subtitle: budget、spending、budget. Apple asks you not to repeat words from the app name, subtitle or category.

Version v1.0Updated Update history
Reading the tags under each field
One field, several stores, several counting rules. The tags tell you which store a text breaks and by how much.
Green, red and amber tags
Green fits. Red is over the maximum: the console will refuse it or cut it. Amber is under a minimum, such as vivo’s 50-character description or the 4-character minimum for a WeChat name.
Characters, bytes and CJK = 2
Most limits count Unicode characters. App Store keywords count UTF-8 bytes, so a Chinese keyword uses three bytes per character. vivo and WeChat count each Chinese character as two units.
“Limit not published”
Xiaomi, OPPO and Tencent MyApp do not publish their limits in public documentation. The tool shows the count and says so rather than guessing a number from a blog.
Checks below the fields
Beyond length, the list flags rules the stores write down: Google Play’s title policy, Apple’s keyword guidance, vivo’s punctuation rule, and fields Huawei or vivo require to be different.
Character limits tell you what will be accepted, not what will be read. Search results and lists show far fewer characters than the limit, so put the key words first.
Three steps
Paste your current listing or draft a new one.
-
1
Pick your stores
Turn on every store you submit to. Set the listing language and, for Huawei, the market, because both change limits.
-
2
Edit the fields
Write the name, subtitle, short description, keywords and description. The tags update as you type.
-
3
Fix the flags, then copy
Shorten the red ones, read the checks and look at the previews. Copy each field into the store console.
The main limits by store
Taken from each store’s documentation. The full list with the original wording is under “Limits and official sources” in the tool above.
- App Store: name 2–30, subtitle 30, keywords 100 bytes, promotional text 170, description and What’s New 4,000
- Google Play: title 30, short description 80, full description 4,000, release notes 500 per language
- Huawei: one-line intro 17 (Chinese) or 80, description 8,000, release notes 500 (mainland China) or 1,000
- vivo: name ≤ 15 Chinese or 30 Latin characters, one-line intro 5–16 Chinese characters, description at least 50
- WeChat mini program: name 4–30 and short name 4–10 with Chinese = 2, description 4–120
| Store | Counts | Chinese character | Source |
|---|---|---|---|
| App Store | Characters; keywords in bytes | 1 character; 3 bytes in keywords | App Store Connect Help |
| Google Play | Unicode characters | 1 (full- and half-width alike) | Play Console Help |
| Huawei AppGallery | Characters | 1 | AppGallery Connect docs |
| vivo | Chinese = 2, Latin = 1 | 2 | vivo review guidelines |
| WeChat mini program | Name: Chinese = 2; description: characters | 2 in the name | WeChat docs |
One intro, four stores
The same one-line intro, “每天 3 秒记一笔，自动生成月度报表和预算提醒” (23 characters, 20 of them full-width: 19 Chinese characters and a Chinese comma), checked against each store.
| Store | Rule | Count | Result |
|---|---|---|---|
| Google Play | Short description ≤ 80 characters | 23 | Fits |
| Huawei | One-line intro ≤ 17 characters (Chinese text) | 23 | Over by 6 |
| vivo | One-line intro 10–32 units, Chinese = 2 | 20 × 2 + 3 = 43 | Over by 11 |
| WeChat mini program | Description 4–120 characters | 23 | Fits |
A version that works everywhere: “3 秒记一笔，月度报表自动生成” is 15 characters (Huawei) and 28 units (vivo).
Why listings get cut or rejected
Most rejections for metadata are avoidable before you submit.
One length for every store
A Chinese intro that fits Google Play’s 80 characters can be more than twice Huawei’s 17 or vivo’s 32 units. Write store-specific versions of short fields.
Wasting keyword bytes
Spaces after commas, repeated words, plurals and words already in the name all use the 100 bytes without adding anything.
Claims in the title
Rankings, prices, discounts and emojis in a Google Play title break the metadata policy and can get the app rejected or suspended.
Copy-pasted release notes
vivo rejects notes identical to the description, and Huawei’s API refuses equal values. Write a real “what changed”.
After the listing: who installs, who stays
A store listing gets the install. App analytics shows what happens next.

Still have a question?
Chat with the team behind TapCub — we usually reply within a few hours on business days.
What is the App Store character limit for the app name?
The app name must be at least 2 and at most 30 characters, according to App Store Connect Help. The subtitle is also limited to 30 characters, promotional text to 170, and the description and What’s New to 4,000.
Is the App Store keyword limit 100 characters or 100 bytes?
App Store Connect Help says “up to 100 bytes”, while Apple’s App Store search page says 100 characters. For English they are the same; Chinese, Japanese and Korean characters take 3 bytes each in UTF-8, so plan with bytes. The checker counts bytes.
What are the Google Play character limits?
Title 30 characters, short description 80, full description 4,000, all counted the same for full-width and half-width characters. Release notes allow 500 Unicode characters per language.
Can I use emojis or “free” in a Google Play title?
No for emojis: the metadata policy rules out emojis, emoticons and repeated special characters in titles. Price and promotion claims, rankings and store-performance wording are also not allowed in the title, icon or developer name.
What are the limits for Huawei, vivo, Xiaomi and OPPO?
Huawei publishes them: one-line intro 17 characters in Chinese or 80 in other languages, description 8,000. vivo’s guidelines set the name at 15 Chinese or 30 Latin characters and the intro at 5–16 Chinese characters. Xiaomi and OPPO show limits only inside their consoles; we found no public number.
How long can a WeChat mini program name be?
4 to 30 characters, with each Chinese character counting as 2, so a fully Chinese name has 2 to 15 characters. The short name is 4 to 10 on the same rule, and the description 4 to 120 characters.
How is this different from the character counter?
The character counter lists limits platform by platform for any text. This page checks a whole store listing at once, across several stores, with policy checks and previews.
