The app is so clear and user friendly. I love how it clearly explains each section and references to the page number in the book for more information. I also love the community forum where I can ask any question, it’s been so helpful.

Up to this point I have just used the app to monitor when my menses came, recently I have started to actually take my temperature again. I like how simple it is to use and that it shares the recommended chapter for that specific section you are looking to input. Being able to make the chart smaller to be able to see like all the months. And I know they have plans on developing more to better it so for now it’s great.

This is one of the easiest cycle trackers to use for fertility awareness, it’s still early so there are more features that will be added, but I love it so far! Plus, there are references to the “Taking Charge of Your Fertility” throughout the app to learn even more!!
