Apple gives you 100 characters of keyword field per localization, and most listings waste a third of it on words that were already indexed by the app name and subtitle. Paste your metadata below — the checker counts the budget, flags the waste, and prints a cleaned field you can copy straight into App Store Connect.
Indexed automatically — never repeat these words in the keyword field.
Also indexed automatically — same rule applies.
Comma-separated, no spaces. Commas count toward the 100 characters.
How the App Store keyword field actually works
Four rules decide whether your 100 characters do any work. The checker above enforces all of them.
- Name and subtitle are already indexed. Every word in those two fields is searchable without appearing in the keyword field. Repeating them is the single most common way indie listings waste characters.
- Commas cost a character; spaces cost a wasted one. Separate terms with a bare comma. A space after every comma in a twelve-term field burns twelve characters for nothing.
- Apple combines terms across fields. You do not need multi-word phrases. With
keywordandrankpresent, "keyword rank" is already covered — spend the saved characters on a term that appears nowhere else. - Plurals and common variants are handled. Adding both
taskandtasksusually buys nothing.

What this tool cannot tell you
Character efficiency is a hygiene check, not a strategy. It cannot tell you whether a term has search volume, whether you can realistically rank for it, or which terms your competitors already own. For that you need to see the actual rankings — yours next to theirs — which is the job Rival Radar does on your iPhone, and what the keyword rank tracking guide walks through. If you are doing a full metadata pass, the 30-minute ASO checklist covers the other fields in order of impact.
Rival Radar tracks your keyword ranks next to your competitor's, catches every listing change they ship, and mines their bad reviews — all from public App Store data, on your device. Free tier included.
