Count the field before App Store Connect does
The App Store keyword field is small, hidden, and easy to waste. Apple gives you 100 characters total, with keyword terms separated by commas and no spaces after commas. This counter helps you catch the mechanical problems before you paste a field into App Store Connect: too many characters, accidental spaces, empty comma entries, and repeated terms.
The tool is intentionally simple. It does not score keywords, estimate search volume, or send your list anywhere. It just keeps the character budget honest so your research can fit inside the field Apple actually gives you.
What the counter checks
| Check | Why it matters |
|---|---|
| 100-character limit | Apple limits the keyword field to 100 characters total. Anything beyond that needs to be trimmed before submission. |
| Spaces after commas | Apple recommends comma-separated terms with no spaces. Removing spaces after commas gives more room for useful terms. |
| Empty entries | Double commas and trailing commas create empty keyword slots. They add no search value. |
| Duplicate terms | Repeated terms waste characters. Apple also says not to repeat words already included in your app name, subtitle, or category. |
| Phrase spacing | Spaces inside keyword phrases count toward the same 100-character limit. Use them deliberately, not by accident. |
Use it with keyword research, not instead of research
A clean keyword field is only useful if the terms are worth targeting. Use the Keyword Research Hub to plan the research workflow, then check exact terms in multi-keyword search, popularity, difficulty, and opportunity score before deciding what deserves space.
For international launches, do not copy the same keyword field into every locale. The Localization Hub and Country Opportunity Finder explain how country-level demand and competition can change which terms belong in each market.
Example workflow
- Research candidate keywords in RespectASO and export or collect the best terms.
- Remove words already covered by your app name, subtitle, or category.
- Paste the remaining terms into this counter and fix length, spacing, and duplicates.
- Move the strongest terms into App Store Connect and track ranking changes after release.
When you want deeper metadata feedback, the ASO Score Simulator evaluates title, subtitle, and keyword field choices together. This page is the quick counter; RespectASO is where you do the research and scoring behind the list.

FAQ
Does this counter store my keywords?
No. The counter runs in your browser and does not submit the field to RespectASO.
Should I remove spaces after commas?
Yes. Apple says terms should be separated by commas with no spaces. This counter flags those spaces because they consume characters without adding value.
Can I use keyword phrases?
Apple allows spaces inside keyword phrases, but those spaces still count toward the 100-character limit. RespectASO generally favors compact individual terms unless an exact phrase is intentional.
