Fastest app I’ve tried

Great app, loads quickly, has all the features I’d need. Only thing I’d change would be to have the ability to change the cycle start date in case you tapped the wrong button! But as I don’t mess that up often, it’s not too much of an issue.

Update—Thanks for the reply! I see, yes it does change the cycle start date when I uncheck that button! :) Now everything works great!!

Developer Response ,

Speed was super important to us -- nobody wants to wait for an app to load when charting. You *can* change your cycle start date, though! Look for it under the Bleeding tile.

So easy to use

This app makes it so easy to chart especially if you are new to it. It also syncs with Tempdrop automatically so it makes it even easier. I love that I can compare multiple cycles at once. You can zoom in or out to see as many as you want because it stacks your cycles. I would definitely recommend.

Best Cycle Charting App

Best overall information for my NaPro to view each month. I’ve learned more with this app than every other competitor. This is for the women who truly want to LEARN their bodies.
