Hiya friends-

Wondering if anyone has any recs for a (hopefully free) period tracker app. I'm not trying to get knocked up, just want to be able to pull out my phone when the GYN asks when my last period was (or when I forget when it was). Usually I'm more like "well it was that weekend my ex was in town and we ruined that towel I liked and I think the O's won so it must have been the 25th?"

ANYWAY, I was just in the app store and there were too many choices so I thought I'd turn to the hivemind. If it makes any difference, I have PCOS and a long cycle (like 33-35 days). Here's a pic of Ruby in a bday hat celebrating her brother's 11th for your trouble...
