Use iProven's BBT thermometer for ovulation monitoring first thing in the morning every day. Reliably track your cycle and figure out which days of the month are the most fertile for natural family planning. A high-precision measurement within two decimal places of accuracy is able to register the slightest rise or drop in a woman's body temperature.
Upgraded Design with Jumbo LCD Screen
With a basal thermometer for ovulation, the reading will take slightly longer than a regular oral thermometer due to the high degree of clinical precision and accuracy. Our new & improved jumbo-sized backlit screen is easy to read in the dark, so you won't need to squint or strain your eyes in the morning.
60-Second Fastest BBT Reading
The upgraded iProven algorithm delivers the fastest accurate reading in only 60 seconds. You can enter measurements manually into a paper fertility tracker chart or download any ovulation tracker app and input the data yourself (independently, does not have Bluetooth app syncing)
30 Memory Recalls & Improved Features
Built-in memory recall of the last 30 readings is perfect for when you fall back asleep or forget to write the temperature down. The small waterproof tip is rigid for enhanced precision with less chance of deviation. The gentle confirmation sound beeps softly, subtle enough that it won’t wake your sleeping partner. Hold the button to switch between °F/°C easily
