A lot of time people don't eat exactly at the same time, so the starting time differs each day. I think it would be a lot easier if it works the same way as the "zero" fasting app.

Where you choose what type of fasting you want to do and the moment you start fasting, you just hit the start button (and there is still an edit button to change the starting time if you forgot the click the starting button) and that it then start the countdown till you can eat again.

This way it is a lot more practical and faster to use than the current implementation.
