Quick answers for the web, iPhone, iPad and Android.

A book or chapter will not load

Check your connection and try again. Previously opened chapters are available from the local cache. If the problem remains, close Ottisk completely and reopen it. When contacting support, include the book and chapter.

There is no sound

Check the volume and selected output device. An “Audio” label beside a language means that audio exists for that edition. Narrated chapters are also marked in the contents.

Offline mode

The text of an opened chapter is cached automatically. If an edition has audio, you can save the audiobook from its contents. Do not clear website or app data while you still need it offline.

Sync

Create an anonymous code on the first device and open its link or QR code on the second. The code grants access to positions and cards. If you lose it, it cannot be recovered by email because Ottisk does not create an account.

The language is wrong

The language selector is at the top of the shelf and in Profile. Interface, reading and learning languages are configured separately. Russian, Spanish, German and English are available.

The microphone does not work

Allow microphone access for ottisk.app in your browser or system settings. It is used only by practice modes that need it, and the recording stays on your device.

Do I need a subscription?

No. The current version is free and contains no in-app purchases.

Still stuck? Email toistev@clndr.es with the book, chapter, device and a short description.
