A great app for using the NFP method

For me, it’s the best app for using NFP safely, easily and hassle-free. It always works, and the customer service team are really friendly and knowledgeable should you have any questions. Even if your subscription is currently on hold due to pregnancy, you still have access to all your previous cycles.

Ideal for paperless and secure NFP applications

I’m still fairly new to the world of NFP. Whilst doing my research, I not only realised quite quickly that the symptothermal method according to Sensiplan is the most reliable, but also that there are very few apps that use this method. Ovolution is one of them!!! What makes it special is that it’s very easy to get to grips with, as they’ve managed to digitise the familiar cycle chart – which is perfect for me, as I can now fill it in from anywhere and at any time!

Great app!

Great app! Really intuitive, beautifully designed and easy to navigate. I’m learning so much about my cycle and feel confident with the analysis!

Cla We · Review from the Google Play Store

Great. With the app, you can…

Great. The app makes it easy to record all cycle-related observations. It also handles most of the analysis involved in the symptothermal method and summarises the key points in the statistics. I also particularly liked the information section, where interesting facts about the method, the cycle, trying for a baby, etc. are presented briefly and very clearly.
