Useful!!
I‘m learning phrasal verbs for my CAE exam and I love the app. There are few drawbacks though. At some point push notifications stopped working, no idea why. Quiz sometimes (rarely) would double one question. I‘d love to see more questions in the quiz because once you’ve seen it you remember the answer and don’t think much. Also games sometimes are kinda clumsy. The keyboard in „echo“ is slow. In „word checker“ words are cut in unexpected ways and are so so hard to read. Well that’s my bug report, hope you‘ll fix all that, keep up good work.
