Free ASO Developer Tools
Deterministic utilities to pack keywords, eliminate rejection risks, and optimize app store metadata without guessing.
iOS Keyword Field 100-Byte Packer
Pack maximum search keywords into Apple's 100-byte limit without wasting space.
Apple limits the keyword field strictly to 100 bytes (UTF-8). This tool removes spaces, eliminates cannibalization from Title/Subtitle, and handles multi-byte Cyrillic characters.
Metadata Policy & Rejection Guard
Check titles and descriptions against Apple 2.3.10 and Google Play metadata rules.
Instantly detect prohibited pricing terms ('free'), unverifiable claims ('best', '#1'), calls to action ('download now'), emojis, and rival platform mentions.
Release Notes (What's New) Quality Checker
Audit update notes against App Review Guideline 2.3.12 and Google Play quality guidelines.
Catch generic boilerplate ('bug fixes and performance improvements') that can trigger app review rejections on significant releases.
