Responsive Tip calculator

This project is one of the first project that gives me tough time to achieve and it not because I don't know what to do but it is due to the fact the design is terrible for user experience.

I think it would have been better if the designer of this project make the RESET BUTTON an actionable button like a button that runs the app instead of the reset button.

Secondly, there is a customize field at the end of the percent buttons, what is the user going to do or the user going to press to get their reseponse.

I think the person in charge of this particular app design can do better to optimize user experience.

This is all I have to say about this challenge.
