About this app

Creighton. Sympto-Thermal. Marquette. Billings. So many different methods to track your menstrual cycle. It can be confusing to find one that works for you.
Neo takes the proven elements from these and many others to create an easy, fast, and powerful way to chart.

- Free *45 Day* trial. We want to be sure the app is working well for you! Very low cost afterward.
- Starts up faster than any other charting app. Super easy to record your sign and get on with your life.
- Still works without a cell or WiFi signal. Often there is not a good signal where you may be recording your signs!
- View your chart on your device, going as far back as you like. View multiple cycles at once!
- Access to a powerful web portal where you can create PDFs of your chart, interact with an instructor, and more.
- Share with your spouse! Your data is synchronized in the Cloud and you can share your chart with others that you choose.
- Continuous updates and new features added thanks to feedback from users

Best NFP App I've tried out thus far! Tried one other than this and it was too confusing. This one is simple to understand and you get to chart temp as well as physical charting. It's to the point, the colour scheme green, red, and yellow helps visualisation. Using Ladycomp on the side but charting it on this app it helps me see it all and compare it with each passing month. My highest recommendation for this NFP app!

Easy to use fertility tracking app with colour coding based on the Creighton charting method. Being familiar with Creighton will help understand it. In addition to basal body temperature and cervical mucus, you can also track symptoms like bloating, headaches etc. - but not some very obvious ones like libido and teariness. After the free 30-day trial it costs around €10/£9 for one year's subscription. It can take several days for the payment to be processed during which the app won't work.

Glad it's working well! I'd like to note that the Google payment issue has been fixed for all users going forward.

Hands down the best app I've used to track my cycle. A notes section, symptom recording section, and an entire monthly overview. After trying multiple tracking apps to follow my hormone imbalances, I'm so happy to have Chart Neo
