The name of this app is "Decoder" and you will find it on google playstore. Just go to google playstore and search by decoder and you will find it.
I think this is the best app for mobile users who wanna learn coding but not have a computer. You can practise about 35 programming languages here and I have tried some of them like HTML, C and Python.
Not only practise but also you can solve problems. There are hundreds of easy, medium or hard problems and you can solve them. By solving you will also rise you on the leaderboard.
On Google Playstore, it has downloaded over 1M and it’s rating is 4.4★.
Thank you. :)
