RTranslator
Open-source and offline simultaneous translator for Android
Connect to someone who has the app, connect Bluetooth headphones, put the phone in your pocket and you can have a conversation as if the other person spoke your language. You can also use it like any other translation app, offline and with total privacy.

A few years ago, right after high school, I decided to try to make a simultaneous translation app for Android as a side project, it took longer than expected (about 2 years) and I had to make a lot of compromises (I had to use Google's API and therefore make users use a developer key because at the time there were no free solutions for speech recognition and translation that had good quality). At the end of university, I decided to pick it up again and finally, using OpenAi's Whisper for speech recognition and Meta's NLLB for translation (with both running locally on the phone), I managed to make it free and totally open-source (as it was meant to be from the beginning). The app is still in beta, so I would love your feedback. For now, the app is not in the Play Store, to install it download the apk on the GitHub releases and open it: https://github.com/niedev/RTrans...
