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.

Makes it Easy - Helps me with TTC Blues

We are TTC so it's important to know my fertile window. We've been trying for a while so every morning, I do my fertility thing and get sad that we just aren't getting pregnant. This helps me a lot because I can still track, but looking at my temps and seeing my most recent "failure" isn't the First thing I do every morning. I can take my temp, put it down, and get to the fertility stuff when I'm emotionally ready for it.

No problems so far

I got the Vinca and not Vinca II due to price. I figured if I like temping after a few months, I’d invest. It arrived quickly in discreet packaging, it did ship from another name so watch out, and the device paired easily with my Bluetooth. Takes temperature quickly and easily. I roll over in bed when I first wake up and recover it when it beeps. It’s still early, but I’m really enjoying it thus far.

It’s Ok, but...

Honestly,I can’t say I would recommend this thermometer. For the price, it takes quite a long time to get reading (with no reliable feedback whether or not the phone is syncing to it - I think the app needs a clearer progress indicator that "the temperature is being taken”.) I get constant messages on my phone that the connection failed, while simultaneously showing that the thermometer is in fact connected. The calibrating step never worked for me. Honestly it is too unreliable with too little feedback and a high price, plus no easy way to return. I guess if you are willing to fork out the extra money go for the Vinca II instead or really - just get a better thermometer. The app is so well designed that plugging in the numbers manually is not a big deal. This thing is more trouble and confusion than it is worth for me.

Makes Life Easier!

For years I have been NFP charting using paper and graphing my own temps. Although the Femometer Application does not follow my NFP (Billings Method) perfectly, it is close in many ways. I was hesitant to buy this but am so glad that I did. It wakes me up without waking my husband, I don't even have to open my eyes! I can wait to turn on the application on my phone til later in the day or do it early morning and when I do, the date/time/temp are automatically stored and graphed! The whole process is streamlined! I wish I knew about it years earlier. This version does not have the digital readout but it works great and I can see the temp on the application. I would recommend this product to all ladies who chart! It has just made the whole process so much nicer for me, I am so happy with it!
