Cranslate: Offline Translator

Cranslate writes down what people around you say and translates it into your language, on your phone, without the internet.

Start a session with one tap, on the phone or on your watch. The phone hears the speech, writes it down and translates it. Each line appears with the translation first and the words that were heard below it.

WORKS WITHOUT THE INTERNET
Speech recognition and translation run on the phone. After a one-time download of the models for your two languages (1.5 to 2.5 GB), Cranslate works offline: abroad, in a shop, on a bus, at a station.

ON YOUR WRIST
Install Cranslate on your Wear OS watch, and a tap on the watch starts a session. The watch shows each new translation in large text and taps your wrist when a line arrives. The phone can stay in a pocket: with "Wait for the watch" on, the watch starts a session while the phone is locked, and both listen.

CONVERSATION
On the Talk tab, two people talk, each in their own language. Cranslate tells which of the two languages it hears and shows each line in the other one. Each line is a bubble on its speaker's side. Swipe a line that landed on the wrong side to hear it again as the other person said it.

36 LANGUAGES
Cranslate hears and translates Bosnian, Bulgarian, Cantonese, Chinese, Croatian, Czech, Danish, Dutch, English, Estonian, Finnish, French, German, Greek, Hindi, Hungarian, Indonesian, Italian, Japanese, Korean, Latvian, Lithuanian, Malay, Maltese, Polish, Portuguese, Romanian, Russian, Serbian, Slovak, Slovenian, Spanish, Thai, Turkish, Ukrainian and Vietnamese. Its screens speak English, Spanish, French, German, Portuguese, Russian, Serbian, Hindi, Indonesian, Chinese, Japanese, Korean, Thai, Vietnamese, Turkish, Italian, Dutch, Polish, Ukrainian, Czech, Slovak, Romanian, Hungarian, Greek, Bulgarian, Croatian, Bosnian, Slovenian, Danish, Finnish, Estonian, Latvian, Lithuanian and Malay.

PRIVATE
Nothing you hear or read leaves the phone. There is no account, no advertising and no analytics. History keeps the lines on the phone and can be turned off. Saving the audio is off unless you turn it on.

FREE TO TRY
Cranslate listens 10 minutes a day for free, on the phone and the watch together. Cranslate Unlimited, one in-app purchase with no subscription, lifts the limit for good and stays on the phone without the internet.

HISTORY AND RECORDINGS
Past sessions stay in History with their time and languages. A conversation shows as bubbles, as on the Talk tab. Tap lines to select them: merge neighbouring lines of one speaker, or choose another language for a line. Copy or share a session as text, or delete a session or a single line. With Save the audio on, the sound of each session is kept: play it on the audio track, or only the selected lines, hear lines again as one or in another language, export it as a WAV file or delete it. Export all sessions and recordings as one file and import them on another device.

MODELS
The app downloads the models for your two languages once. You can also get a model yourself: each model has its link, and a model file can be exported and imported.

WHAT IT NEEDS
- A 64-bit phone with Android 8 or later, 4 GB of memory (RAM) and up to 2.6 GB of free space for the models.
- For the watch: Wear OS 3 or later, paired with the phone.
- Recognition works best within a few meters of the person who speaks. Loud noise and distance lower the quality.
