The best out there- including privacy!!

Love this app, and the privacy it provides really helped make my decision to use it. Privacy and accuracy are very important with this kind of app. This app applies to many different npf choices with ability to have input of different types (creighton - cm cks, sympto-thermal cks) so if you prefer to chart a particular way out of old habits or are learning more this app is the one for you. The newest version provides a more modern look, with all the same abilities as before. It’s nice to get a birds eye view of the current cycle. The colors still correspond nicely to cycle days (no silly flowers or faces, thank you). My only request- is to bring back the ability to easily swipe to the previous days and swipe forward again. Right now, you see where you are from a total phase perspective , and have to go into log symptoms and then move back and forth between days. It feels a little awkward. Maybe being able to tap on the cycle would then take you to current day and then swipe? Idk, just a request. Not a deal breaker for me. The app is too good to walk away from bc of a simpler preference.

Developer Response ,

Please reach out to me at so I can better understand what feature you want back -- in the new design, you can move your finger in the top bar to switch between days instead of swiping. You can also tap on a day in the bar to go directly to it.

What I’ve been looking for

I’ve been charting my cycle for family planning for a decade, and have *finally* found the app that has it all. I can track my cervical fluid with ease, while also adding in any cross checks I might want to each cycle, and can see it all in one place. You can “scale up” or “scale down” depending on what data you want to track, it’s very user-friendly, and knowing that it follows European guidelines for privacy (which are more rigorous than HIPAA), I have zero worries about my private health information going anywhere except my healthcare provider. Great value for the price!

Best cycle tracking app!

Chart Neo is exactly what I needed as I started fertility awareness. I love that it syncs with my Tempdrop. It makes it so easy to record cervical mucus, temp, tests, notes, etc. The chart view is really helpful in identifying patterns around my fertile window, and the calendar view is useful too. It’s more than the typical predictor-type apps because it relies on the data you input to determine where you are in your cycle. Overall, I couldn’t be happier with it!
