## What is Simply Fast?

Simply Fast is a beautifully simple, no-frills companion for time-restricted eating. Rebuilt from the ground up for the latest iPhone and Apple Watch, it keeps the same clean, one-glance design while feeling right at home on today's devices. Set your window, glance at your progress, and get on with your day.

[Features]
• Clean, distraction-free design for iPhone and Apple Watch.
• Set your fasting start time to any half hour of the day.
• Choose a fasting duration from 12 to 23 hours.
• A live progress bar shows your current fasting or eating window, with the time remaining at a glance.
• Apple Watch complications for modern watch faces, so your window is always one look away.
• A notification at the start of each fasting and eating window.
• Your schedule stays in sync across iPhone and Apple Watch.
• No sign-in, no account, no ads, and no pop-ups.
• Private by design: the app collects nothing and sends us no information.

[Important]
You should consult your doctor before starting or changing a fasting schedule. Simply Fast supports time-restricted eating only, not full-day fasting such as 5:2, and it does not track or store a history of your fasts.

[Feedback]
We would love to hear from you. Please reach us through the app support page (https://www.mpathy.tech/contact-us).

### 4/5 — Great for shorter fasts

*2019-06-16*

Fantastic integration with Apple Watch, looks beautiful on the sub-dual.  
No login with Facebook or whatever, no useless complexity or ads, no subscription.   Just a nice fasting timer. 
I’d happily pay more if it supported longer fasts, but perhaps there is more to this issue than I imagine. 
I’m doing 36/12 currently but will be using this when I get to a maintenance weight.

**Developer response:** Thanks for the kind review. It essentially captured our design goals. Supporting different types of day or long fasting methods along with time restricted eating increases the complexity of the interface and hence avoided. Hope you reach your maintenance target soon and start using our app!
