BBT. Does the app predict temps?

Pauline
Hello all 
​I've only just started recording my bbt since I got this app. This morning my temp was 36.8c. When I went to add that it already had 36.8 in the box. Same as yesterday then I thought, but no, the day before was 36.3c. 
​Does it predict what your temperature should be?
​It would be great if you had a feature where when you click on the temp chart you can find out what it means and what you are aiming for. I don't really ave a clue. 
​Thanks
