Why you can't use Natural Cycles offline

Natural Cycles only works when you are connected to the Internet. As the algorithm runs on servers, and not within the app, it is important to have an internet connection. This way we can get your results to you straight away and ensure that they are always up to date.


We are currently working on an offline mode, which will enable you to enter data even if you don’t have an internet connection but will not show you a result just yet. This way you will be able to use Natural Cycles at any time, once you connect to the internet your data will sync and your fertility status for the day will show up again in the daily overview.

Cycler tip: If you don't have internet connection, keep measuring as usual every day and add the values as a note within your phone so that when you have internet connection again, you can easily add all data points.
