### 1/5 — Dont't buy

*2017-05-19*

Absolute waste of money, dont buy!
Only ine page in the whole app,mtontrack your temp, but could not even enter a single temperture.
No explanation, no information anywhere!!
Wish I could give it back and get money back

### 1/5 — Not very good

*2014-06-30, version 1.4*

Not user friendly, no instructions on using it properly (took a guess, not sure if correct). Not worth $1.99. Make your own in excel...

### 1/5 — Waste of money

*2013-04-28*

Doesn't allow you to chart a temperature of 97.18 F - says it's not in range!!!  Very disappointing.

### 3/5 — Helpful

*2013-04-03*

This app was helpful in finding my hormone levels. Especially when realizing hormone related migraines. Also helps as I have endometriosis and this helped as I run a low grade fever the week before my cycle hits. Very informative. Only bad thing is the temperatures aren't wide enough. I wake up with a temp below the lowest on this chart. And when I ovulate my temp is high than the highest on the chart. Maybe make a wider value of temperatures? I know mine is sometimes closer to 96 F rather than 96.8F. Just a suggestion.

### 1/5 — Don't waste your money

*2012-12-11*

This app was a waste of my $1.99 it was not very animated or helpful at all if I could give it zero stars I would it not worth 1 star

### 1/5 — this app does not work

*2012-09-27, version 1.4*

And is not worth the $$$ so don't bother downloading it!!!!

### 2/5 — Disappointing

*2012-01-02*

I'm sorry I bought this. It's easy to enter temperatures, but you cannot name files in a way that works for you. Worst of all, you can't revise an entry! So if you forget something or make a mistake, when entering dates not on the day of, you have to delete all and start over.

### 5/5 — BTT

*2011-01-29*

Very simple and informative program.

### 1/5 — Celcius?

*2010-10-02*

This program only allows temperatures entered in celcius
