Tempdrop: The Basics
Tempdrop is a wearable BBT thermometer that makes it easy for you to keep track of your fertility and ovulation by making it easy to record your basal body temperature (BBT). The Tempdrop armband is worn on the upper arm when you go to bed and takes your temperature readings throughout the night, saving you from having to wake up early to record your temperature.
OvuSense: The Basics
OvuSense is a fertility monitoring device that helps you track your cycle pattern. It notifies you about your ovulation and your fertile window, helping you identify the best time to try to conceive during each cycle. There are two types of OvuSense Sensors:
• OvuFirst Sensor This is ideal for those with regular 24-35 day menstrual cycles and is worn either in the underarm or on the wrist while sleeping.
• OvuCore Sensor This vaginal sensor is ideal for those with irregular menstrual cycles or PCOS and is inserted into the vagina to measure the core body temperature.
Using Tempdrop vs OvuSense
Both devices work as you sleep, and while the Tempdrop bracelet is worn on the upper arm before going to bed, the OvuSense OvuCore sensor is inserted into the vagina, like a tampon. Some women have reported that OvuCore may slip out when using the toilet. Additionally, it has to be removed and cleaned carefully before logging any readings the following morning. You also can’t use the OvuCore sensor when you’re spotting or on your period. So when it comes to ease of use, Tempdrop wins it because it’s hassle-free.
The Accuracy of Tempdrop vs OvuSense
Tempdrop works by measuring your basal body temperature, while OvuSense measures your core body temperature. This means that OvuSense bypasses any issues associated with the luteinizing hormone, making it more accurate in monitoring your ovulation. Additionally, it also notifies you of a missed ovulation in a given cycle, giving it an accuracy advantage over Tempdrop.

Tempdrop vs OvuSense: Which Product Is Better?
Both Tempdrop and OvuSense provide an easy way to track your fertility and cycle, and they both cater to those with PCOS or irregular cycles.
However, using Tempdrop for birth control is easier since it simply involves wearing the armband when going to sleep and syncing it with the app in the morning. Although using the OvuSense OvuCore sensor involves inserting the sensor into the vagina, making it uncomfortable for some, it does provide more accurate information. Also, unlike Tempdrop, you can’t use OvuCore when you’re on your period. This may make it more of a hassle to use.
Overall, deciding which of these fertility monitors is better comes down to personal preference.
