Great app for ovulation, period and pregnancy attempts!


Really love this app! I have used it religiously for over 5 years when attempting to get pregnant, having failure in getting pregnant (showing my doctor what I have tried to obtain a fertility specialist referral ) plus tracking my cycles while going through miscarriage, fertility treatments and attempts at conception naturally. Not to mention this app transitioned me through a pregnancy, return of my cycle and trying again for baby number 2. I had no defects, problems or use with this app. Completely reliable!! I am still using it and rely upon it completely for tracking periods, ovulation and planning. Really easy to use and modify for your own use. This app tracks menstruation cycles, optimum ovulation, moods, weight, basal temp, "love dates" and any meta data you desire to track when things happened and when. I have used it to back-search data for when I took shots or took specific tests. I found it invaluable in when going back to the doctor for information they needed about outside specialists or dates on when things happened. Highly recommended!

Really good, but needs to be integrated with the Health App


I’ve been using this app for a long time and I like it a lot. I like the ability for documenting detailed symptoms and moods, and the ability to add notes and custom icons. The reminders are very helpful. I like having different choices for customizing the skins/appearance of the app as well. I also like the fact that you can set up a startup password and use the fingerprint ID.

The only problem I've had with this app was a couple of years ago when my data got deleted from my phone even though I hadn’t done an update. I contacted the company but was’t able to retrieve it because I hadn’t created an account yet, so it wasn’t being backed up to their server. I don’t know exactly what happened, it might have been something that I did. I just wish I had setup an account early on to prevent the issue in the first place.

I really wish that they would integrate this app with the Health app to make it easier to get the data that they have in common into that app concurrently, instead of having to enter the same data into multiple apps. I would give it five stars if they did that.

Handy but has some problems


I've been using this app for about a year and a half or so. It's worked pretty well, though I find a few things that aren't very user-friendly, but I've learned to work around them. However, here's my biggest problem: Last week my iPhone suddenly got erased accidentally. Bummer. To make matters worse, I hadn't backed up my phone in 3 months. So when I reinstalled my phone, this app went backwards 3 months and said my period was 100+ days overdue! OK, I get it, I should backup my phone more often. But here's where I have a problem: why do I bother having an account that I'm signed into if it's not going to remember my information on a cloud somewhere and restore it to my phone? If it's only going to store my months and years of period tracking locally on my phone or iTunes, why bother making us sign up for an account? If I'm signed into an account, then it should retrieve all that information when I login, and it shouldn't affect it if you get a new phone or lose your phone or erase your phone, etc.
