Common Issues

A language pack is missing or a download has stopped

Open the Models screen and download the complete offline language pack before first use. Downloads require an internet connection and can be paused and resumed. Check your connection and available device storage if a download stops. A model is available only after the file is complete and passes runtime validation; wait until it is ready before translating.

Speech recognition or translation is not working

Allow microphone access in iOS Settings and make sure the required language pack is ready. Try a short recording in a quiet place and confirm the source and target languages. After model preparation, recognition and translation run on your device without an internet connection.

Photo translation does not recognize the text

Allow camera access when taking a photo, or photo library access when selecting an image. Use a sharp, well-lit image with clearly visible text, and check that the required models are ready. OCR and image translation are processed on your device.

Voice cloning sounds unclear or does not finish

Record a clear 5–20 second reference sample in a quiet place, using your own voice or a voice you have permission to use. Check microphone permission and model availability, then try again. If it still fails, include the sample duration and any error message in your report; you do not need to send the recording.

There is no sound during playback

Check the device's media volume and whether sound is routed to Bluetooth headphones or another audio device. Wait for speech generation to finish before playing the result. If text translation succeeds but audio does not, mention that distinction in your report.

Do I need an account or subscription?

No account is required. Navigo offers optional Weekly, Monthly, and Yearly Pro subscriptions and a separate one-time Lifetime Pro purchase. Open Navigo Pro in Settings to view current local prices and billing periods, purchase, or restore an eligible purchase. Manage or cancel a subscription in your Apple Account settings. Downloading models and checking purchase status need an internet connection; translation with prepared models works offline.

Data and Privacy

Recordings, translations, generated audio, voice data, and downloaded models are stored locally. Speech recognition, translation, OCR, and voice generation take place on your device. Microphone, camera, and photo access can be managed in iOS Settings.

Deleting the app removes its local data. Keep your own copies of important content before deleting data or uninstalling. Support cannot retrieve, recover, or delete content held only on your device. See the Privacy Policy for details.
