The exercises are not really new. Everything seen in the various brain training apps made before only much better and more fun.
This app is every few months for just one day for free, but even now I can not recommend it. Especially because of this already mentioned several times miserable German translation. Although you can play in English with the necessary basic knowledge, but then you need at the games with language and verbs naturally correspondingly longer, which ultimately then also no fun.
Maximum 2 stars.
