Bug fix desperately needed

The app NEVER remembers my login info. This makes it frustrating to use. Would love to see it fixed!

Go back to the softer colors, too much for waking eyes

I’ve been a dedicated user for about four years now, so I don’t need to really describe how much I like this app. The new bright colors on the interface, even for the dark setting, are too bright for reading in the dark. The dark setting is black and bright white, so while I’m trying to read the little bitty regular font text with a black background, next to bold font on a bright white buttons, I got an instant headache! We are taking waking temperatures, this is too much for my waking eyes.

—find a way to integrate individual day reports in the chart interface. Too many clicks to adjust a day. Very menu heavy. Other than that, EXCELLENT APP, just use softer colors that don’t contrast to much!

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.
