Great fertility tracker
Daysy is a great tool for me. My husband and I have used it exclusively for pregnancy prevention for 8 months and it's worked thus far. It gives us about 2 weeks of green "safe" days and 2 weeks of red "unsafe" days to have sex every month. I've missed quite a few readings, missed 2 weeks straight while on vacation, and then I got "unsure" readings for about 2 weeks, then it went back to normal. So you definitely have to remember to take the readings, which is the hard part for me. When I'm sick and can't breathe through my nose, or when I need to pee first thing in the morning it can be uncomfortable because I have to take the reading while in bed, holding my pee. Anyway, it is accurate and it does the job it should. The app could use some updating, as it takes a long time to sync, and wish I could add notes like 'sex' to days 2 weeks before. It only lets me add notes to recent days.
