Best app for those practicing NFP


I have tried the Glow and Kindara apps to practice Natural Family Planning (NFP). This app is so much easier and more practical to use. The cycle charts on Glow did not show up after adding my data after I had my second baby. Also, the Glow app didn't account for my pregnancies and for postpartum (nursing), and this CycleProGo app does. The Kindara app was annoying - it was not very intuitive when you tried to edit start dates for the cycles. It was also difficult to see all the data on the chart. For those practicing NFP, CycleProGo is the best app.

Clunky and not free


I'm sure the functionality of the app is fine but the user interface is clunky and frankly hard to look at. It also could be simplified so that you didn't have to click around as much. It needs some TLC from a good graphics designer to try and bring it near the UI of the GLOW app. All this makes it hard to plop down the $35/yr they want for you to get any real use out of the app.

I think a better pricing model would be to just charge $5.99 or whatever for the app and forget the subscription service. I think they'd generate more revenue that way.

Highly recommend this app


This is much easier than filling out charts on paper. The app helps you figure out the phases and peak day automatically (after it has happened). So glad they created this!
