How does femSense detect ovulation?

femSense uses the well-known temperature method to detect ovulation and takes it to the 21st century. Immediately after ovulation, the body temperature rises by a tiny amount. While this miniscule rise is difficult to determine using conventional thermometers and usually takes several days to get a result, femSense is capable of detecting this temperature rise while it's happening due to the continuous measurement of your body temperature. The femSense algorithms use hundreds of temperature values to confirm your ovulation instead of single temperature values measured once a day.
