Customer Insights

1. statements would be another nice addition.) Are these bugs fixed in the paid version?It is a good editor but After running the code , when I accidentally touch my devices back button its getting into editing screen, Which must only be done if double clicked the device back button And I thought I can change my program title later , But I couldn't find anywhere.

2. TyThis is the second coder app I'd tried, and to be honest, I would willingly stay to this app! I was blown away with the built-in keyboard! It made everything easier, but I wish there is an option to somewhat change its height? And idk if it is mentioned, but can I access the directory using my file manager? I want to import some .c files to the app.

3. It rarely has any bug and if it crashes, it's probably the user's fault because of the running program using too much memory.It's a great compiler, along with its features for easier and faster typing.

4. Overall, it's so amazing! Never knew coding would be as this easy in a mobile device! Would definitely recommend to my classmates and friends!atof from stdlib.h doesn't seem to work.

5. When using a phone in "gestures mode" (without back or home buttons), if you use the built-in keyboard, a swipe-up can freeze the app writing infinite spaces or symbols in background.

6. This can be improved I would be very happy if there was a small window which would tell you that the code is going wrong somewhere for example you if you have missed a semicolon, then the small box shows the worning that you have missed the semicolon at so and so place.

7. Also, please I'm begging you .... When we click the keyboard to go-to uppercase either stay that way until we un-uppercase or do like gboard... Double clicking it real fast goes to uppercase and stays.

8. It's super difficult to find your code files to move them later -- not sure why, but have seen others mention it.

9. When I start typing something, the program usually doesn't suggest anything.

10. I tried other compilers and it worked perfectly on them, thats how I knew that my logic is not wrong and the font is at fault.

11. The app is incredibly great, but it lacks conding a program in multiple files.
