## Most critical reviews (4 lowest-rated)

### 1/5 — Useless

*2025-05-22*

This app doesn’t work an appears to just be a pdf

### 1/5 — Temps only in Celsius

*2010-02-10*

Seriously? I have to open a conversion program just to figure out what temp to enter since I have to convert from fahrenheit to Celsius for it to even let me enter a temp.  I would have expected something that simple even in a free app.  It certainly was not worth the $2 I paid.  Also there is no explanation of what the symbols and lines mean on the graph, no way to change the predicted fertile phase or ovulation date, and the website listed doesn't work.

### 1/5 — Don

*2010-01-21*

Not user-friendly at all.

### 2/5 — Really inflexible app

*2010-02-15*

I thought this app would be a lot more flexible than it is. I don't care that it's in Celsius, but I wish you could skip a day (it does not let you do so). I also really hate apps that assume all women ovulate on day 14 and menstruate on day 28. If I knew I was going to ovulate on day 14, I wouldn't need this app! It's not ideal for women with irregular cycles.
