Will I still have an accurate estimate of my fertility without the femSense patch?

Using the app without the patch will give you a pretty good idea of when you will be fertile.
When you use the sensor patch femSense can measure and confirm ovulation and the algorithm has more exact information about your cycle, which it can include in its calculations. This means that the predictions are more exact and personalized. If you would prefer the app to be more personalized, accurate and to include confirmation of ovulation please visit our webshop to order your femSense patches.
