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!
I've been using the PeakDay 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.
Kicks me out sometimes and worries me that all my data is lost. Not a super reliable app, but works well when it is working.
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
It's a great app design, but it is missing an essential feature of the original app: brief reviewing of the CCL fertility rules. This is much more expensive than what it used to be. I pay $35 a year for the CycleProGo app. This new app costs $59.99 a year, which is almost double what I have been paying. This app has all the features of the old app with some features taken away, and the app is very unreliable and doesn't connect most of the time. I might have to start paper charting instead.
