App store metadata checker
Check iOS and Google Play listing text, field lengths and missing information before opening the console.
Counts use Unicode code points and also show UTF-8 bytes. Combined emoji or accents can be counted differently by a console. Apple’s keyword reference specifies 100 bytes while its search guide describes 100 characters; check the final field in App Store Connect.
