Created a forum account just to add my voice to the chorus of disappointed customers.
The period prediction is incorrect, and the only option is to confirm the error! What a joke. “Edit” allows only a change in period length, not start date. Fiddling with settings allows me to change cycle length, and thus screw up all other periods (not everyone has exactly regular periods, for a variety of reasons, you ignorant jerks), or turn off prediction altogether. I don’t want to turn off the prediction as it is generally useful to have an idea of when to expect my period, even if it’s off by a couple days, based on the last one I had. What we thus end up with is a series of false meaningless historical data, so that I can have day to day usefulness with the prediction, or accurate historical data that is essentially useless because Fitbit won’t integrate it into trends.
If your algorithm cannot handle integrating real world data, then you should just delete this feature altogether until you find some capable programmers. That’s literally to be the reason fitbits are supposedly useful.
Entirely agree with everyone who has said this app must have been made by men, with no input from actual human females.
