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

Straightforward course with practical examples with real-world usage I got through a lot of software courses, but this one suits me the best. The theory is divided into small but logical parts and it's often connected with practice and real use-cases and that's the most valuable part of it. Some practice questions are ambiguous and needs more 'intuitive' approach. But overall, they are making the pages better and better every day.

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.

Learning is like a video game The fact that there are exercises and projects in every theory section. I believe you should provide the solution or some hints, cause sometimes exercises are more complicated than theory.

My opinion. Please find below my opinion. 1- The course organization is very good. 2- The absence of videos and the focus on reading helped me achieve better understanding. 3- The reading time for each step is acceptable. 4- The course maintains good quality. 5- The practice section is also very good.
