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

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.

Best platform to learn Java and Kotlin The code reviews help you adopt best coding practices, the integration with IntelliJ is fantastic and I love the way the lessons are written in a concise way, much better than video in my opinion. Oh! and the exercises are great!

I love this learning platform I love this learning platform, the only one I return to so often and so eagerly.

I so far found it a great platform I recently came across the platform by way of a web search on a technical subject; I decided to read on and explore the site. I'm currently a non-paying member enrolled in the data science study plan. I find the project- (portfolio-) based training constructive as well as the grouping of topics towards a given domain, e.g. data science. I already have a background in Engineering and found the topic coverage suitable and looking forward to complete a project; I will likely become a paying member.
