How to use it
Use every character for a reason.
The tool counts Unicode characters, removes empty entries and duplicate keywords, and checks whether a full keyword is already present in your app name or subtitle.

- ✓Avoid repeating exact words from the app name and subtitle.
- ✓Remove duplicate entries and prioritize specific, relevant intent.
- ✓Read the field as a set of combinable terms, not a user-facing sentence.
- ✓Record the change date and compare ranking movement after release.
FAQ
App Store keyword field questions
Does the App Store keyword field have a 100-character limit?+
Yes. The iOS App Store keyword field allows up to 100 characters, including commas used to separate terms.
Should I add spaces after commas?+
No. Spaces after commas consume characters without adding search value, so a compact comma-separated field is more efficient.
Should I repeat words from my app name or subtitle?+
Avoid repeating exact terms already used in the app name or subtitle. Use the hidden field for complementary words and relevant combinations.
Does this tool save my keywords?+
No. The counter runs in your browser and does not send the app name, subtitle, or keyword field to a server.
