Back to BBT thermometers. What is so special about a BBT thermometer that a regular thermometer can't do the same thing for? BBT thermometers are more accurate and work on a smaller 0.1 degree Fahrenheit scale versus a regular thermometer reading of 0.2 degrees Fahrenheit. When temperatures are charted, a line graph is produced that visually represents a woman's monthly cycle that is broken down into the three phases of menstrual phase, Follicular phase, and Luteal phase. The Follicular phase of a woman's cycle is when her body begins exhibiting signs of pending ovulation. The Luteal phase of a woman's cycle indicates ovulation has occurred. These phases can be seen on a chart by the elevation of temperatures. The more precise and accurate the temperatures the more reliable the data is for determining each phase of your cycle.

BBT Thermometer Reviews
1. EUDEMON Digital Basal Thermometer (Purchased from Amazon 8/2014 for $18.74, currently unavailable.)
I LOVED this thermometer. It was the first one I purchased. The only downside to it was it could take 3-5 minutes to take your temp orally. My bladder did not love this thermometer and I opted for an upgrade to a different device that promised quicker results. I have recently had to use this thermometer again (more on that in the following device reviews) and it still works!!!! It even had the correct date on the screen when I turned it on. I hadn't turned this thermometer on since sometime in 2017. At this point, I am extremely impressed with the longevity of this device and super happy it pulled through as a trusty thermometer when I needed it most.
2. Wink by Kindara (Purchased from Kindara 8/2017, $129, currently unavailable)
I wrote a blog review about this product November 2017 and loved everything about this modern tech device. It was a much more expensive device than what I was using but for the quicker temperature results and the auto sync of data, it was worth the price. Until it stopped working. I only used the Wink thermometer from September 2017-May 2018. And I tried going back to it this past month in February 2020 and it is completely dead. The battery will not charge and the metal plastic ring around the device to hold the top with the thermometer probe onto the main unit has broken off. This seems to be a poorly constructed device and as I have gathered from others online, a common theme among those users in the FAM community. Kindara no longer offers their Wink thermometer. They currently have a new device they have poured their energy into promoting called the Priya Sensor, which has yet to be released but appears to be a vaginally inserted sensor that syncs to their app that allows you to have constant fertility monitoring. The device is taken out and put back in every 29 days. After my disappointment with the Wink thermometer, I do not intend on supporting the Priya Sensor. Their customer service has a bad reputation and many have lost out after purchasing the Wink. In fact, I am a little leery about having a device inside me for a month with all the concerns about EMFs.
3. Tempdrop by Tempdrop, Ltd (Purchased from Tempdrop, Ltd 5/2018, $150)
I decided to see what all the hype was about with the Tempdrop, a wearable external device that is worn while you sleep. The data collected pairs and utilizes algorithms with their specific app. I only used my first Tempdrop for 3 weeks in May 2018 until I found out I was pregnant then I used it again for a couple weeks postpartum when my menstrual cycle returned. I wasn't in the habit of charting with a baby so I quit using it and then started to use it again in December 2019 when the battery started warning me it was low. I again quit using it and then finally changed the battery in February 2019 and a day later it quit working. The liner between the two shells separated which prevented the device sensor from working and collecting temps. Tempdrop's customer service is excellent and I have been sent a new sensor which I have worn without issue for one night so far. My concerns currently are if this device will break again when I go to change the battery. I really want to love this device but I am very apprehensive.
4. Femometer Vinca by BONGMI (Purchased from Amazon February 17, 2020, $28.99)
Similar to Wink, the Vinca is a smart sync thermometer that allows you to take your temp and it syncs to an app. It utilizes it's own charting app so I have had to change my charting method to their app from Kindara's app. So far this device it fast and has been very reliable in it's syncing technology. It actually works better than the Wink and is so much cheaper. The thermometer I have does not have a screen display for me to view my temp but they do offer a Vinca II model that does for $49.99. I also love how sleek and portable this device is. It will definitely travel well if I need ti pack it. This is my first cycle using it and I am very pleased with how quickly the thermometer works and how easily it syncs. I always had issues with my Wink thermometer syncing despite it being advertised as auto-syncing. I never found the auto-sync to work and always ended up manually entering my temps into the app. I am currently using the Vinca with the new Tempdrop sensor that was sent to me. My first night temps with the Vinca was 97.33 and the Tempdrop was 97.17. I did wake up frequently to breastfeed my little one and by the time I took my temp orally I had previously woken up to a restless baby about an hour prior therefore disrupting my 3 hour consecutive sleep cycle. (3 hours of consecutive sleep is rare for me as I am still breastfeeding so I can't really follow that rule for FAM are strictly as I should).
So these are my current thoughts and experiences about the numerous devices I have used for BBT temping. I'm going to continue to use the Tempdrop in conjunction with the Vinca for the 30 day algorithm to kick in and then I will re-evaluate how I feel about each of these devices.
