Install while you have a connection
Download Rasterdeck Translator from Google Play and complete the model downloads needed for your selected features. Keep the phone connected until setup finishes. Allow storage space for the models as well as the app; download size and setup time depend on the models and connection.
Check the languages and features you will use
Text translation supports 42 languages. Voice and photo translation support 40, while Pro voice cloning supports 28. Check the language listing rather than assuming every feature is available in every language. Spoken playback can depend on the offline voices installed on your phone.
Try a short conversation before buying
Typed translation is free. The voice trial lets you test spoken translation on your own phone before choosing an unlock. Choose the source and target languages, speak a short sentence, then check the translation and playback. Take turns rather than speaking over each other.
Verify the offline setup yourself
After downloads and any unlock activation have finished, enable airplane mode and turn Wi-Fi off too. Translate a fresh sentence rather than reusing a previous result. Try both conversation directions and spoken playback. This checks the setup you will actually use when a connection is unavailable.
Match the phone to the task
The listed requirement is Android 10 or later with at least 4 GB of RAM. Larger models and voice cloning ask more of the phone. Response time varies with the device, model and length of speech; a short trial on your own phone is more useful than a promised universal speed.
Understand when a connection is needed
Conversation processing runs on the phone after setup. Model downloads, unlock activation and purchase verification use a connection. The app does not require a translation account or subscription. The website is separate: it handles purchases and uses Rasterdeck website analytics.
