Why Vinca?

  • "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 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's lipstick-like shape makes sure no one is easy to find out about your little secret of tracking 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

  • Download our app, uncap the Femometer Vinca and pair via bluetooth. No need to pair again next time.

  • Put the metal tip of the Vinca under your tongue, keep your mouth closed and try not to move the thermometer 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.

So Far So Good!

Very easy to set up and use. This is my first month using it, so I’m hoping to learn more about my natural cycle. It so nicely uploads and tracks in the app, which also links to my Apple health app!

Great. Plunks it in so you don’t have to

I love the shape Of the thermometer and it’s pretty easy to connect to my app. I like that it beeps to let me know my temp is ready. The only things I don’t like are 1) when you set the alarm for the thermometer it doesn’t go off until you take the lid....if I didn’t set my phone daily I would miss my measurements. 2) the lid needs to be off to connect to the app Love this company and all there products. I use the ovulation strips and there pregnancy strips

Very nice

This is my second Vinca-- the first one, the toddler was playing with and somehow got water inside-- and it works very nicely. Easy to pair (they HAVE long since fixed the software issue from '17 or so where you had to have the thermometer open before you turned on your phone app, but I still sometimes see folks ask about it) and the "hey, take your temperature" beep you can set it to make is loud enough that the only time I slept through it, I also slept through my phone alarm. The only thing I'd change is that it's pink. Well, rose gold, and nowhere near as pink as it looks in the pictures, but I really miss my white one that isn't offered anymore. When that's the only complaint someone like ME can come up with, it's a pretty decent item!
