What are the app name and subtitle limits?

The app name allows 2–30 characters. The subtitle has a separate 30-character limit.

Are keywords counted in characters or bytes?

This tool uses the 100-byte limit documented in App Store Connect Help. Plain ASCII letters use one byte each; accented letters, emoji, and non-Latin characters can use more.

Do spaces and commas count?

Yes. Separate keyword terms with commas and remove spaces after commas. Spaces within a phrase are allowed.

How are emoji counted?

The character fields count each visible emoji as one character. When counts differ, the tool also shows bytes and UTF-16 units. Confirm your final text in App Store Connect.

Should I repeat words from my app name in keywords?

Apple recommends avoiding terms already included in your app name, subtitle, or category. Use the space for other relevant search terms.

Does promotional text affect search ranking?

No. Use its 170 characters for updates and announcements, rather than keywords.

No. Your text stays in this tab and is cleared when you reload or close it. No account is needed.

Make room for useful keywords

Use relevant terms, separate them with commas, and avoid unnecessary repetition. Apple’s guidance is summarized below.

Separate terms with commas: Remove spaces after commas. Keep spaces within multi-word phrases.
Avoid repeated terms: Skip words already in your app name, subtitle, or category.
Choose one form of a word: Avoid adding both the singular and plural of the same term.
Avoid generic and filler words: Use specific terms instead of broad words such as “app” or “game”.
Use symbols only when relevant: Keep special characters for terms that are part of your brand.
Use promotional text for updates: Promotional text does not affect search ranking.
