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.

Response from developer

Dear valued customer, We’re so sorry to hear about the difficulties you experienced—how frustrating! We always strive for our technology to work smoothly, but we understand that issues can sometimes arise. Our live support team is available to help with any problems, and we encourage you to reach out so we can assist directly.

We truly care about your experience and would love the opportunity to make things right—please get in touch so we can help. You can email us at peakday@peakday.com or visit peakday.com to chat live.

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

Response from developer

Emileighpratt, We are sorry to hear you're having trouble with the app interpretation. Please know (as the app lets you know as you start) that the app needs a full cycle of information to know where you started in your cycle. After completing an entire cycle, it will interpret according to your data. Please don't hesitate to reach out if you have any questions--as there are real people here to help you resolve any questions.

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.

Dear kicklucy, We appreciate your concerns about PeakDay and we agree with you! We are looking forward to future updates to technology and devices that will help with data syncing. And we are always looking into ways to improving the app like including imports. Thank you for your feedback!
