Verdict	For manga, games, and foreign-language video on Android, this genre of app is the only tool for the job — just walk past the fake countdown and know what the permissions mean.	If you want one free app that handles almost every language and situation, Google Translate is still the safest default.
Pros	Translates what nothing else here can: games, comics, video subtitles One-time $29.99 purchase instead of a subscription Google's engine underneath, so language coverage is huge	Supports nearly 250 languages — the widest coverage of any free app Camera translation, handwriting, and voice conversation modes Free offline packs for dozens of languages
Cons	Needs screen-capture and overlay permissions — it watches your display Paywall uses a fake countdown timer No voice, no conversation mode — this is OCR-on-screen only	Quality drops on low-resource and long-tail languages Privacy-sensitive text is processed on Google servers Business document formatting is not its strength
