Works great, very attractive design
I like everything about this thermometer. It is simple to use, attractive design, measures to the hundredth of a degree. It paired automatically with my iphone and the app interface is easy to use and informative. As other reviewers have mentioned, as long as you turn the app on before you take your temp, even if you open it before you go to bed so it’s on in the backgrounfmd, then the temperature immediately records in the app and shows up on the nicely designed graph.I chose this thermometer for a few reasons.1. My doctor told me to start tracking my basal body temperature so that it will inform what is going on with my hormones. She said to get one that goes to the hundredth.2. I knew that checking my temp each morning would get super old, especially if I felt like I was making too much noise or waking up my husband for a long time, and this one has a backlight when the temp starts taking and when it’s finished with the reading, so I do not have to use a seperate light.3. It was a little more expensive to get one that is smart and has an app associated with it, but I knew that it would be worth the small added expense for the convenience of having the info automatically stored in my phone, so I would not have to write it down and then remember to take the book with me to the doctor….and I was right.I recommend this product to anyone shopping for a BBT thermometer.

Works great but somehow moisture is trapped in it
I love the features of this thermometer; it’s quiet enough to not wake my husband, it has a good memory for the temps, and I like that it sends the data to my app. I also appreciate the flexible/safe tip, because I basically fall back asleep every time I wait for it to get a reading. The only thing I don’t like is that somehow there is moisture trapped behind the screen, so now it’s a little hard to read since it looks foggy. I didn’t submerge it or anything, I just used it on a humid day, so I feel like this might be a defect.

Not reliable
I wanted to love this thermometer, but it’s just not reliable.1. Syncing: Many other reviewers have mentioned that syncing is an issue, and that is true – you HAVE to have the app open in the background WHILE you are taking your temperature in order for the app to reliably sync your temp. (For reference, I have a Samsung S9.) If you try to sync later, even if the thermometer reads “connected” it may or may not record your temp to the app. If it does sync later, chances are it will double record your temps, like it did in one of my pics.2. Temperature accuracy / inaccuracy: Super questionable. This is my first time trying to track my BBT. I’m not trying to conceive but am trying to learn more about my health after reading the Period Repair Manual by Lara Briden, a book that I would highly recommend to all women, especially those TTC as it’s all about helping your body ovulate. Anyway, I’ve been using this thermometer for about 6 weeks now. I keep it under my pillow and use it as soon as I wake in the morning. I usually wake up a couple of times in the morning so use it each time, just to be on the safe side, but have noticed that sometimes my temps are wildly different which seems weird to me. For example, this morning I took my temp two times, once at 4:30 when I woke because my partner got out of bed, and again at 7:10 when I got up and my temps were 97.59 and 98.18, respectively. (Those are 0.59 degrees apart! WHAT!) So today I decided I would test it consecutively to see what my temps were just a few minutes apart. As you can see from the pic, I used it 4 times in a row and got different temps each time. The first was 97.93, then 98.02, then 97.95, and finally 97.91, so the widest difference is 0.11 degrees. These aren’t terribly different…but wtf? I don’t want an approximation of my temperature, I want a reliable reading to record in my tracker. How am I supposed to know which one to record?! I can guess, based on where I’m at in my cycle, but then what’s the point of tracking my temp at all? It’s exasperating. I ordered a different bbt thermometer so keeping my fingers crossed that it’s better than this one.3. The app: Sucks, overall. I do like the line chart it creates as it makes it easier to see spikes and dips (assuming they are correct…). However, once you start a new cycle it basically deletes all previous bio markers. You can still track your temp, but all the info about your period / ovulation is wiped from the chart making it impossible to compare your current cycle with your previous cycles. Basically, it is useless.4. The thermometer: Other than accuracy, it’s a decent thermometer. It takes 1 min and 45 seconds to take your temp, which feels like a long time but whatevs. It beeps quietly, it has a yellow backlight that is not blinding and only turns on for a couple of seconds when you actually need it: when you turn it on, and when it’s done taking your temp. It stores 30 previous temps so that you don’t have to remember what the reading was, and when your app doesn’t sync you can still go back and record it in the other app you’re using to track your temps.

Le top du top ce thermomètre. Ultra facile ultra précis. Je l’ai acheté dans le but de bien cibler mon ovulation avec la symptothermie. Résultats après 2 ans d’essai bébé avec un thermomètre classique, je suis enceinte avec seulement 1 cycle d’utilisation avec celui-ci. Hasard ou pas…je ne crois pas. Sa précision est juste incroyable

Das Thermometer funktioniert einwandfrei und verbindet sich auch immer mit der App. Ich kann mich nicht beklagen. Das beleuchtete Display ist auch sehr sinnvoll!
