### 5/5 — Баг

Загрузить книгу из сафари не удается, приложение просто вылетает, и после вообще отказывается работать, пришлось даже переустанавливать. Очень грустно, ведь идея классная((

Das Spiel ist Klasse aber zu viel Werbung

### 4/5 — Awesome! But…

*2025-05-30*

This is the best app for this, I love it! Though, it tells us in a pop up that we can always “turn of the ads for free”, yet when I click “turn off ads” it brings me to its $5 pro version in the App Store. Can I turn off the ads for free please? Like you said I could?

*2025-02-22*
