Why Vinca II?
"Precision & Efficiency Matter"
Complete your measurement in as little as 30 seconds once Vinca gets familiar with you. The 1/100th degree precision ensures your bbt is always accurate.
"Silence is Golden!"
Vinca II beeps to let you know she's ready to measure, or she just finished a measurement. Adjust the volume anytime in app in case you're worried about waking up the Sleeping Beauty...
"Subtle & Sweet"
Vinca II's lipstick-like shape makes sure no one is easy to find that you are trying to pinpoint your ovulation unless you want them to.
"Dive deep into your fertility symptoms."
Together with the app, it tells more than just a result but also an unique "story" behind.
How to use Vinca II
Download our app, uncap the Femometer Vinca II and pair via bluetooth. No need to pair again next time.
Put the metal tip of the Vinca II under your tongue, keep you mouth closed and try not to move the themometer around. When you hear three beeps, you've successfully measured your BBT. Now repeat this every morning - before you get out of bed and after at least 6-8 hours sleep.
The Femometer app learns from every piece of data you input and calculates your conception rate for each day. The app then provides personlized insights so you can prepare for your fertile window.

What people think of Vinca II
This basal body thermometer is exactly what i was looking for. This device looks so professional, sleek, and I love that it has a case! Keeps it clean and secret. The device turns off and on, just by opening and closing the case. I like that because i was a little worried about something beside me that's looking for a bluetooth signal. BUT this is not the case, I can sleep in peace knowing the device isn't looking for a bluetooth signal. This company's customer service is AMAZING! And that's so important now a days! Thank you so much, I recommend this device to all my friends!
Very good experience
Intuitive, quick and precise
Generally good. I like that it shows the temperature, but obviously it takes away from the small Size and light ness of the Vinca I model. It’s slightly harder to hold on to in mouth when one is half or barely awake. But it’s good besides that: fast, accurate and reliable I believe.
I had been using the first gen of this product for about 8 months when this one came out. I was so excited for the updates that I bought it right away! I've been using it for a few months now and it has been so amazing. The battery life is great so far, I LOVE having the option to read my temp on the screen, and the ease of bluetooth to upload it to the app on my phone is exactly what I need. The app is super user friendly and I can track my cycles super well. I know exactly when I ovulate and am able to understand my mood swings, cramping, cravings, breakouts, and so much more. I love using this product hand in hand with the book Taking Charge of Your Fertility. It is incredibly empowering to use this as a natural method of birth control and I love how connected I am with my body. Thank you !!
