Clean but Unintuitive

For you to start and end fasting, you have to go to schedule for the fast and adjust the day and time. Instead of just being able to tap and start/end/log the fasting. There is a fine line between smart engineering and overengineering. This is over engineered and unpleasant to use.

Pretty good I just wish there was more customization options

SimFast is really good and it does what it supposed to do. I just wish you could change the color of the widgets and how the home screen looks instead of green and is very end. I wish there was more fasting options like it goes all the way up to seven days like the standard popularized fasting app do

Needs to be improved.

Keep losing input images and take tons of time to save.

Features

Gandan works with Apple Health to record weight, workout data.

Studies show that eating all the time makes your body unable to take a break from digesting.

During fasting, as your glycogen depletes, your body switches to ketosis, which is referred to as the body's "burning" mode.

Gandan send push at start time of fasting and end time of fasting.

Gandan Intermittent-fasting Timer helps you track your fasts, your progress, and your goals.
