### 1/5 — Read the reviews

*2019-11-10, version 1.2.0*

Waste of data! Guess Apple store doesn’t care about quality apps just as long as they pay to have us fall for it!

### 1/5 — Useless

*2019-09-29, version 1.2.0*

App crashes before it opens.

### 5/5 — Developer needs to respond !!

*2019-01-30, version 1.2.0*

This app works just like the picture in the description. After you add your name and birthday, you just need to tap on your name at the top. Otherwise it is just like the bad reviews, light lines without any description. Too bad the developer has not read the reviews and explained this!

### 1/5 — Just a poor representation ruined by ads for other apps

*2018-06-13, version 1.2.0*

If you take the time to look at days other than day opened app then redirects to stupid game that otherwise would not 
Get the time of day from this useful tool to understand your body’s natural cycles.   Bad showing on the part of the developer.......bad show

### 1/5 — Too frequent ads

*2018-06-01*

Does the calculation but too frequent full screen ads to be any use.

### 1/5 — Ruined by popups....

*2018-05-20*

Every time I tap a new pop up appears.... 👎

### 1/5 — Not Even One Star

*2018-04-15, version 1.2.0*

You've been warned. Waste of time. How did this get on the App Store?  Apple, Wake Up!

### 1/5 — graphics / legend / IOS 11.2.5

*2018-02-16, version 1.2.0*

thin line weights almost invisible, no legend to identify color of lines

### 1/5 — Tells nothing

*2017-12-23, version 1.2.0*

You can see some colored lines, but it doesn’t say what they are and if shoes no dates.

### 1/5 — Rubbish

*2017-04-16*

Doesn't work.
