First the good: Cornelsen has some of the clearest and most practical grammatical explanations, with good examples and nice memorable pictures. Colorful highlights really help and the grammar topics just “click” better somehow. Unfortunately, this app is riddled with bugs making the experience extremely unpleasant. Constantly having to re-login, lessons freezing or not loading properly forcing a reset. It is not pleasurable to use. The “adaptive” lessons are really formulaic and get boring easily. What is truly unacceptable is I noticed some glaring grammatical errors. (For example, „wollte“ is listed under the Präteritum for mögen, „ich“ is labeled as a Verb in an answer). My recommendation: save your money and use it to buy one of Cornelsen’s excellent grammar aktiv textbooks instead.
One of the worst apps I have ever downloaded. If you download this app it is almost impossible to login to your account if you have the book I strongly recommend you do not download this app
The app will only be supported until 31 December 2026, after which it will be shut down. Subscriptions will not be renewed beyond this date. You do no...
