### 5/5 — Ez and effective

*2023-04-22*

This app is easy to use, and effective to loose weight.

### 5/5 — Useful

*2022-02-23*

I am new to fasting searched around for a app most were much more expensive and not user friendly like this one. Easy to use no nonsense tracker.

### 5/5 — Great

*2022-02-16, version 7.3*

This is an easy great app

### 1/5 — Caution

*2021-02-22*

This app is a rip off designed to fool you to buy it at 99 cents - but it’s a WEEKLY subscription of 99 cents not a 1x charge the developer is trying to trick you into thinking. 

I heard that Apple is clamping down on apps that manipulate users this way and I hope this one gets busted. 

I would gladly support this developer if their charge offered a good or reasonable value. 

But not $50 a year ($500 over ten years) for a simple countdown clock.

**Developer response:** The app clearly stated it is a weekly or monthly subscription. And it was reviewed and approved by Apple before it was released.

### 5/5 — Seems very easy to use

*2020-09-14*

The app seems very easy to use

### 5/5 — Easy

### 5/5 — Has potential

*2020-04-26, version 7.3*

It’s very pretty and has a nice interface. It feels a little hard to move around the areas in and I sometimes press the wrong button but I really like it and will be buying a pro version. Keep up the good work!

### 2/5 — Thumbs down

*2020-03-29*

Not user friendly no instructions

**Developer response:** Thank you for your review!

### 4/5 — Should be a way to delete data if needed

*2020-02-11*

I love this app, except I accidentally added a digit to my waist measurement and I cannot delete it. Now my averages and chart are messed up. Please allow a way to delete accidents like this. Also the save button covers the metric change button so i can’t use metric instead of imperial.

**Developer response:** Thank you for your review!
You can delete data from Apple Health App.
