Seriously the best fertility awareness app, even better than charting by hand and laying things out the way I want. Everything is there, it's so easy to enter information, and it's cute AND rated high for accuracy. NFP is always our only go-to in our marriage, and this makes it super simple. I especially love that it has in-app explanations of calculations, charts, and fertility awareness in general. I LOVE IT!

I love this app. I discovered it when reading s medical journal that rated it highly based on it's perfect chart intrepration. It matched all mine. However, its algorithm is based on stm sonifbyou aren't temping it isnt very helpful. I was sad to see when they rolled out the premium version they took away some of the previous free features like emailing a pdf😔

I have used this app for several months and I liked it a lot. It really does use the sensiplan rules. It has nice design (except for the thumbnail :) and I found it easy to use. Very accurate. I don't use it anymore bc I find paper charting works better for me but if I ever come back to an app, it will be this one. (The only thing I did not liked much is the fact that in first cycle days the graph zoomes in and I do not see the whole month in the axe, but it's just a detail)
