5 stars: The app is great for learning every programming language and is up-to-date with new contents. There are also a bunch of Free courses which you could complete. But the only problem is that even if you complete the entire free course you won't get any certificate of completion which felt bad as even if we earned it, we can't have it. I wish that it could be mine.
4 stars: Overall its an excellent app. Course's are explained with simple examples and also very easy to learn. But facing some problems with the audio, it doesn't work sometimes. The pro version is also good. If you are thinking of upgrading, go for it!! Also it would be great if you add some explanation in program examples. It would help beginners.
5 stars: I love this app. It's fully free and teaches you several programming languages. It has short animated videos(they are great) and excercises which help you learn. As of know I didn't found any point for deducting any star, so I have given it 5 stars. Ps: You will require a good concept grasping skill, otherwise you won't be able to understand what is taught.
4 stars: The app is good at getting a general overview and understanding of particular subjects. It's very beginner friendly but not in depth. Like middle school or high school curriculum. They should definitely combine subjects. Like python then advance python, so it's a full program. But these are nice overviews to get an idea of what the subject is all about.
5 stars: I love the app ...
