Natural Cycles is more than a period tracker. Most other fertility tracking apps assume your cycle is 28 days long, even though 87% of women have cycle lengths that don't fit into the 28 day pattern... We understand that birth control is not a one-size-fits-all. Your cycle is unique to you! Our algorithm uses personalized temperature data to confirm your ovulation, reducing the risk of you being assigned an incorrect fertile day. Unlike period trackers, the NC° app allows you to identify your fertility status daily, so you can prevent pregnancy or plan for it with greater precision.
From birth control to planning pregnancy and every cycle in between – Natural Cycles is there for you with each stage of your fertility journey. Still not sure? Download the app and test out our Demo Mode. The app supports syncing with Apple Health.

I don’t know about US, but if you are from Europe I don’t recommend. I subscribed paid a good amount of money, asked for thermometer. They write they try to ship it within 2 days - zero information. I messaged them - zero response (one week has passed). The communication is ridiculously bad… in the app they send me notifications, urge me to add the thermometer, which I don’t have and at that point I don’t even know if I will get it at all? So far it just looks scammy and until communication improved I won’t change my review.
It’s a huge shame because the concept is awesome, possibility to order thermometer is awesome I signed up without hesitation, but now I’m just extremely disappointed. Please improve your communication and transparency.
Why every Iphone app is so expensive
I used an app on my Samsung that was great to observ my cyces (ovuview),when i changed the phone I descovered is not evelable on Apple. I tried to check if this one is for me, but I have to pay, it is not what i expected
By far the best type of birth control
Very insightful and user friendly. It may be a bit costly but I believe it is worth it. Been off the pill for a year now and I feel amazing! Thank you NC!!!
Still not convinced
It’s pricey and basically only good price for the app you will get if you sign up immediately after trial period, after that price go up quite significantly. New update was full of glitches, very annoying. Overall I like the idea of being hormones free, measuring temperature every morning is easy. I wish the algorithm wasn’t so strict, it took 6 days to confirm my ovulation and made me doubt my body, not nice...
Very good!
Practical and useful
great app!
it does exactly what it should! easy to use and neat design. and what is very important for women on the move - it can be used on few devices simultaniously. highly recommended if you look for cycle planning app.
