I supported the crowdfunding of this app when they were first building it because it sounded amazing. There are lots of fertility apps and trackers out there, but I feel like with each one I’m looking for something a little different. This one is IT. I am so grateful for the creators of this app! I was able to move everything from Kindara over easily, so I still have my years of charting and stats. They’ve worked hard to get everything women wanted and get the app running seamlessly. The customization here is phenomenal. Transitions are smooth from data entry, to chart, to calendar, to stats. And to top of off, I switched methods recently from sympto-thermal to creighton and I am able to add stamps to my chart and keep everything in my app! I love this app so much. I will absolutely recommend to anyone using Fertility Awareness Method or Natural Family Planning.

The best app I’ve found!

I have a horrible time charting on paper, so I really don’t do it. If you write something down incorrectly, there’s the mess of having to scribble it out or erase it, and it gets messy fast. Because of this, I’ve tried a bunch of apps to help me chart with the Justisse method, and none of them will ever compare to this one. Other apps were clunky and/or didn’t let me include the data I needed. So glad I found this, because I was ready to give up!! This app is amazing because it’s super clean and intuitive and not overwhelming,, and yet it is highly customizable for whatever fertility awareness method you use. I seriously feel like crying because I’m so happy I found this. Keep up the amazing work with this app, and thank you for all the hard work you put into it!!!

The best charting app hands down

The Read Your Body App is absolutely amazing. The most important things to me in a charting app are 1. privacy, 2. customization, and 3. customer service if something goes wrong. The privacy on this app was what attracted me to using this since there is absolutely no cloud component. The customization is unlimited and the developers are continually coming up with more available features and continually improving on the available options for the users to get the most out of the charting experience. Finally, the customer service is beyond incredible. Any small issue is handled and if a solution isn't immediately available, the developers continually communicate with the user as to their progress.
