Fantastic for busy or distracted people!
I use this because I cant always remember when my period is likely to start or when I experience horrible symptoms like bad cramps, diarrea, bloating, or other aches. I like knowing that info for when I see the doc to see if there might be a problem or not. The back-up feature is also great to make sure all the data input is safe too!
