Ratings and reviews

If you're a hands on learner like me you'll love this app! I've tried a lot of learning apps for coding before and always felt like I wasnt retaining the info from the typical reading assignments. Code Plays example style lessons helped me understand and absorb the information much better. It's the most engaging learning app for coding I've ever used. Only improvement I can think of is maybe adding a vocabulary tab so if you're unfamiliar with a term you can look it up.

Easy to use. But too many bugs. Even the 'Bug' button has bugs issues. Template cannot be cleared or we can't go back to default. Many codes in the index are missing from the previous version. Also the biggest bug in this current version is the app doesn’t recognise or run a code which is just made,saved and cleared. In brief, this current version doesn’t run a pre made code, existing in our devices. And not a single photo can be uploaded. Except those, this app is SHUUUUUUUUUU.

It's truely good and "playing" mode is perfect to learn by doing and seen the result instantly, every mode actually. It's very usefull. Ther are very few ads, mostly just small ads in the bottom of the screen, it doesn't interrupt at all, ads don't disrupt you. I was using the free version and since it's really good I realized Pro version is worth paying. Great app!
