Super glitchy

There are a few glitches with this app. This is not acceptable for an app that you have to pay for. This will not work for me.

No longer allows data input after last update!

After last update, (3 days ago), no data, other than temperature, can be entered. Please fix this!

Really Wanted To Try

I really wanted to try this app, but I couldn’t even get past signing up before it froze and wouldn’t let me continue. I put my name in and got to the date of my last period and it froze. Tried it 3 times and kept freezing in the same spot so unfortunately I deleted it.

Terrible

The app doesn’t regulate data like it should. I put in all the info it needs and it still says I’m fertile every day of the week. Don’t trust it, use a different platform like natural cycles

I want to love it

There is so much I like about this app. It has a beautiful, simple interface unlike others I have used. It’s supported by CCLI. It’s affordable. However, the Apple Watch syncing is clunky and a dealbreaker for me. For one thing, the Health app needs to be open at the same time in order for PeakDay to read the temperature. This doesn’t consistently happen even then. But the biggest dealbreaker is that there doesn’t seem to be a way to import past data. I have literally years of data from using other apps, and it would be too time consuming to input it manually. PeakDay has so much potential, I hope it advances technologically to be a contender with similar apps.
