Hypnoledge is an interesting app with a novel concept that I generally like. However, there are also a few things I don't like.

First, in my opinion, the app should allow you to learn the same language in which you choose the user interface. (For example, learn English if the app is in English). Furthermore, I don't like the way you learn vocabulary. Each vocabulary word is assigned a picture, which is often incomprehensible. So you don't know what the vocabulary you're learning actually means, and you have to look it up somewhere else to not rely on guessing.

In order to pass the grammar exercises, you have to read a PDF beforehand, which in my opinion could have been solved much better and does not meet the standard of a modern learning app, since PDFs are not optimized for mobile devices and there are much better and more interactive ways to learn something. This is really just bad in comparison to competitors!

I find the hypnosis part somewhat good in principle, although I think it doesn't help if you haven't heard the vocabulary at least once before. Otherwise, you have no idea what you are listening to except gibberish and you learn nothing!

The second part of the app for personal development is limited exclusively to hypnosis sessions, which is not a bad thing in principle. However, I didn't understand the system with the hypnokeys. Apparently I can buy individual hypnosis sessions for hypnokeys, but I find the same sessions in another tab of the app also accessible for free.

In my personal opinion, it should rather be two apps, since the target group for language learning and personal development are partly different (even though i personally like both).
I also have the feeling that this two-pronged approach leads to that both parts do not reach their full potential. I hope that they keep developing on some of these main points instead of just adding new languages or so.

For now I think it is usefull if you either just want the personal development part or if you at least know the language that you want to learn at least a little bit and if you just use this app in addition to some other language learning app.
