One tip for improvement

This is by far the best period app, has the most options for symptoms and moods and it’s super easy to use. Only on problem or tip I would say to make it better, put in an option to chart when you have spotting. I have been having a lot of spotting recently and it would be nice to be able to enter in the data so I can compare the number of days and amount of spotting I have been having compared to each Month. That’s the only reason I didn’t give 5 stars. Otherwise amazing

Lost Info

I recently had to restore my phone, and though I’ve synced my app previously to my email when I had to restore my phone all of the app information was completely lost. I’ve done this once before and was able to get the app information back, however this time it’s just all completely gone and it’s very upsetting.

I used it more as a women’s health journal and had a lot of dr visit information on it as well as things about my relationship. Is there a way to get my information back? I had it in a back up for my phone, but it seems there’s no way to get this information back onto the app?

Amazing App

I have been using this app since 2015 and I LOVE IT! I have kept up with it since and I knew immediately when I was pregnant because of how accurate this app is. It allows you to keep track of not only your periods but also when you ovulate and what days of the week you are fertile. I’m now 6 months postpartum and started using it again and it’s still accurate!
