Very good platform to learn Kotlin. I am using Hyperskill to learn Kotlin, with both the web version and the Android application. I especially like "The problem of the day" and the option of being able to review the concepts already seen.

Your lessons are not well explained I recently started learning Python and at the beginning, it was going well but recently, the classes haven't been so explanatory. I was advised by my friend to find somewhere else to learn but I want you to know why.

Well motivating platform for a… Well motivating platform for a beginner. Not push too much and free users also can be benefited by Hyperskill.

Very good, but could be better! Ok, I am using the platform for a fair amount of time now, and overall I really like the format, exercises and projects. However, there are some disadvantages: 1. Firstly, the order of the topics when learning something is not natural and as it should be!!! For example, I am learning currently the Comparable interface then databases then Comparator interface (does not make much sense since both interfaces are mainly used for the same thing and should be learned after each other). 2. Sometimes, the theory behind the exercises is not discussed in the lecture. 3. And last but not the least, IT IS A REALLY EXPENSIVE PLATFORM! Actually, I believe it is the most expensive one...In my opinion it should not cost more than 20-25$ per month, but it costs 50$!!! Just unbelievable.

No daily life replenishment The app started out great, it was quirky, fun, and intuitive. I was planning on using this daily. About the 2nd or 3rd day I got a few questions wrong, and eventually spent my daily lives limit. Came back the next day enthusiastic and the lives never replenished! I figured it was a glitch. 3rd day, same result, no more lives. I waited a week and still nothing. So I uninstalled the app
