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.

What people think of Vinca
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.
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!
It’s easy to use. I like it. It looks solid
Beautiful design, precise and useful! The application is smart and easy tu use, I love it !
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!
