Available learning content depends on your language pair. App screens may vary with version and settings.

Any questions?

Does Tolki work without Apple Intelligence?

Yes. Apple Intelligence is not required for translation. Download the right language packs beforehand. Additional local models are available for certain languages. Optional AI features may vary by device.

When do I need an internet connection?

For initial language and voice downloads, app updates, purchases and restoring purchases. Translation itself then runs offline on your iPhone.

What is free, and what costs extra?

English and your chosen home language are included free. Each additional language is a one-time €0.99; all languages at once with Tolki Complete are a one-time €5.99 (prices in Germany; other App Store countries show local prices). There is no subscription. The app shows the current price before you buy.

How much storage do the language packs need?

It depends on the language. Individual packs can take up several hundred MB – the additional offline models for Danish, Norwegian, Swedish and Catalan, for example, are around 340 to 360 MB per direction. So download only what you need, ideally on Wi-Fi. The app shows what will be downloaded beforehand.

Will Tolki work with my hearing aids?

Tolki supports audio output through compatible hearing aids connected to your iPhone. Available audio routes depend on the model and iOS. Try Tolki with your devices; our support team can help with questions.

Are my conversations sent to the cloud?

No. Speech, text and camera content are processed locally for translation. Favourites and learning data also stay on your device. In local chat, you share content with the connected conversation partner.
