Ovulation app

I use the Flo app. But an app is based on averages. And a cycle doesn't work like that; it does its own thing. I have to adjust it manually quite often.
I do ovulation tests with 2besure because we're doing IUI. But that's not exact science either, because when exactly does your egg release after the peak? Luckily, I can now feel pretty well when my egg has been released.
As long as you haven't been trying for a year yet, I'd go by your own feelings and desires. Your body will sort it out if you listen to it.

I use 'My Calendar', an app with a pink flower. I use it to get an idea of when to start using ovulation tests. I only do them during the 3-day period before the predicted ovulation until I get a positive test, to keep the pressure from getting too high.
In this app, you can choose in the settings whether it uses a standard term for the calculation or takes the average of the last three cycles.

I use the menstrual calendar app (P.C.) – it's really really nice. I've tried several apps, but I've been using this one for a few months now. By the way, ovulation is just an estimate. For more precise ovulation tracking, I'd recommend using ovulation tests.

I used: my calendar, Maya (the most accurate in my opinion), p.c., and Flo.
It worked out much better than expected.

Good luck!
