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.

Wonky Notifications

I've had this app for several years now. I rely on it to remind me when my period is coming (in extremely regular). I use it at the OBGYN when my doctor asks about my most recent cycle. I take notes etc. This app has worked wonderfully, but recently it's been acting up. When I input my period, it continues to notify me and tells me my period is late. It does this for the entire cycle (even after I've added my period) until green week. It's been doing that for I believe this entire year. I didn't receive any notifications at all this month, then bam today my period shows up. I back tracked to check if I missed he notifications. I didn't. It's turned on in my phone, through the app. I didn't get a single notification. I'm extremely frustrated with how this app is working lately. I tried to review it and I see there is another version of it. I don't want to download that one and lose all my data. Please fix the notification issue ASAP.
