Ratings and reviews

After a long search, I finally found the best app for writing Java codes, easy to use for beginners. Better than that, it's offline and free🔥 I hope it stays like this-forever,We really need it. From now on, u can write codes everywhere without problems.I also liked the font😍,But there is something disturbing when the code results come out(terminal),the writing is very stuck to the edge of the phone 🤏,Shortcuts can be add,Keyword detail, save file in folder with we can open it on same app😊❤️

Very easily learn to coding.

if you are looking for offline compiler it's the best but you need to understand how it works
