Comments on PeakDay Fertility Tracker for Android

★★★★☆ Katy Bridges · Dec 3, 2023
I've been using the Peak Day app for a few months now as a part of NFP training. It's been very useful, and the premium version is a bit more convenient, but the free version is very useful for recording Temps and symptoms. Also, the support staff responds very quickly (same day) to questions.
★★★★★ Nadine Mc · Mar 7, 2023
As a new user to an app for fertility tracking, Peak Day made it easy to understand, input and interpret my personal information. I love the sharing options and chart analysis.
★★★★★ Jeff & Bridget Bockey · Apr 18, 2024
I really love how this app is in line with our faith. It has worked great for us in tracking our fertility. We used it to avoid getting pregnant, and then conceiving. We are now pregnant, and it gives a daily update on how far along we are with our little one. Including tips for mom.
★★★★★ Heather Slaymaker · Sep 20, 2023
Love this app and that it is so easy to use. It is easy to identify the 3 phases and is so user-friendly. If you don't remember the rules for phases, it helps to identify them and break them down. I love how it can be linked to my husband's phone as well. I just need to figure out postpartum and looking back as I'm sure there is a way to look back at the whole cycle/ chart, but it only shows so many days. I would recommend this app to anyone wanting an easy, effective way to chart!
★★☆☆☆ Sarah Jones · Jul 18, 2025
Have to hit refresh after EVERY SINGLE MOVE; click on a day, refresh, look at another month, refresh, save a symptom, refresh, try to add more info, refresh. Very annoying, though I will say I was trying to add past tracking info, so there was a lot of clicking to be done... aside from that, the extra steps are pretty annoying compared to other tracking apps I've used. Why do I need to hit save after entering info, it should just be there like a toggle switch, few more thing, but not enough space
★★☆☆☆ Dr. Jennifer Eastman · Sep 6, 2023
This app replaced the CycleGoPro app. In the years I used CycleGoPro, I can't think of a time I had an issue entering my data. Since the switch, I have had repeated issues entering data to where I am considering returning to paper charting for the first time in about 5 years because my charts are so incomplete. I need to try to keep intermittent paper records to accommodate the app errors, which defeats the purpose! PLUS, Peak Day costs almost twice as much as the old app which actually worked!
