Audio is never uploaded, never sent online, never stored. ■ Many languages, any direction Chinese / Japanese / English / Korean / French / German / Spanish / Italian / Portuguese. UI in English, Japanese, Korean, Simplified & Traditional Chinese. ■ Two modes · Screen audio: translate sound from other video apps · Microphone: translate speech around you ■ One-time purchase, yours forever A daily free allowance to try; buy once for unlimited use. No subscription, no ads. Note: the first time you use a language it downloads its on-device model (one-time online), then works fully offline.

Robin is an open-sourced, unofficial client that shows X posts from people you follow. It is not affiliated with or sponsored by SpaceXAI. Robin shows your timeline in a focused session — posts from accounts you follow, in the order they were published. No algorithmic ordering or additional posts by other people you don't follow. This matters because we use our information stream to form opinions and act; an as-it-happens news feed is good for decision making.

Verdict
The clearest difference is in-app purchases: Robin at none against Fanshu Translator's 1. Robin also leads on update cadence (daily vs every 10 days) and iOS requirement (18.0 vs 26.0). On price, ads and device support there is nothing between them.
