NaturalCycles is the smart fertility monitor providing an effective, simple and natural way to either prevent or plan pregnancies.

NaturalCycles Prevention is the modern way of preventing pregnancies - free of hormones and side effects. A state-of-the-art bio-statistical algorithm analyses your basal body temperature to identify and predict your fertile window. You can optionally combine your temperature data with ovulation test results - our algorithm tells you when, for optimized usage.

NaturalCycles informs you about your current fertility status and also makes predictions for up to 5 cycles in advance. It’s as simple as this:
- GREEN: not fertile / no risk of pregnancy
- RED: fertile / risk of pregnancy - use other contraceptive method (such as condom)
Our method has been scientifically tested to safely prevent pregnancies. With NaturalCycles there is no room for the human error. It is safe, easy to use and 100% natural.

With NaturalCycles Planning, you can simply get pregnant when you want to - no more trying! Our algorithm isolates your most fertile days in your cycle and detects ovulation based on your temperature data. Once pregnant, NaturalCycles monitors your pregnancy and follows your baby’s development.

NaturalCycles Prevention and Planning are fully compatible and allow you to switch from one to the other, profiting from your previously recorded data.
