Super for cycle monitoring

I find the thermometer class, I have now used the first cycle and ovulation was me be displayed correctly.
I measure vaginal and always 5 minutes and think it's no problem to do that right after awakening so.

At first I was surprised when I got the first time saw the "LO" and thought the battery is all, but this ad is only when a certain temperature is reached.

The memory function is I have noticed only later, just when the thermometer is long press the "on" button and the final temperature will be displayed.
