Simplicity Request

Could you please offer the ability to only track periods on the calendar without seeing the purple fertility days? That would be great.

Slight problem

The problem is that we’re it says temperature, I think it’s in Fahrenheit. And I’m Aussie so just sorta left it at the same temperature as it started. Also another thing I feel like this app is more suited for older than 35 year old woman. I will say I’m gen z and quite a bit younger than 35. I guess what I’m trying to say is maybe there could be different countries/age language changes. And if you’ve gotten as far as reading all this THANK U
<3 much love from Australia 🇦🇺😀

I love it

I love this app because I use to have flo and it was a good app but it was a little bit complicated but this app is not complicated but I love it and every time it tells me exactly when I’m going to start my period and when I’m going to end it and so far it’s been right
