App Store keyword optimizer
Paste keyword ideas in priority order. The optimizer removes duplicates, filler and words already indexed from your name and subtitle, then packs as many keywords as fit into Apple's 100-byte keyword field.

Frequently asked questions
Should I use spaces in the App Store keyword field?
No. Separate keywords with commas only; spaces waste characters. Apple combines individual words, so “photo,editor” also matches “photo editor”.
Should I repeat words from my app name in the keywords?
No. Words in your app name, subtitle and developer name are already indexed, so repeating them only wastes space.
Does Google Play have a keyword field?
No. Google Play indexes your title, short description and full description, so use keywords naturally in those texts instead.
