Bluetooth Basal Body Thermometer for Adults - Fertility Prediction | 1/100th Degree High Precision,Large Screen and Backlit, Bluetooth Sync, Ovulation Tracker with Premom

Using this while TTC. Its accurate and I like how it connects to the app. I’ve had it for months and have had no issues with the battery life. Great price as well.

I have really appreciated the convenience and easy use of this BBT thermometer. When I wake up in the morning I immediately stick it in my mouth and it reads my temp in about a minute, then uploads it directly to my PreMom app via Bluetooth. If I happen to have my Bluetooth off for a few days, the thermometer still retains the readings and I can go in the app, reconnect to the thermometer, and it will upload the past temps - I've done up to a week before. I've had this for a couple years now and only had to replace the battery once, even using it every day. I also love that it comes with a case that it snaps into, so I can travel with it in my toiletry bag without it getting damaged.Super handy thermometer - well worth the extra money for the peace of mind you get that you won't lose your temperatures or have to manually input them when you're still groggy from waking up. Highly recommended!

I spent a long time trying to find the right basal thermometer, and this one has been good. I've been pretty pleased with this thermometer and haven't had any of the issues listed below. Yes, it does take a long time to read the thermometer, were talking less than a minute though and that doesn't really bother me (I'm half asleep anyway). Occasionally it will have some issues syncing, but I notice if I sync it right after taking my temps it works better (syncs with the PreMom app). Directions are included to explain how to set up and sync if you need them. Sometimes I just manually enter, and it hasn't been a huge deal.After tracking temps for 3-4 months I'd say the temps are pretty reliable. Occasionally I'll get an outlier temp, but thats just the nature of BBT and its usually due to taking my temp at a different time or under a different condition (which you shouldn't do). I will admit that at first I had been wanting a cuter thermometer, which is a bit ridiculous I know. I didn't think this one was very attractive, but I actually think it looks better in person. I was surprised by how much I liked the big screen, as it is actually pretty useful early in the morning when I'm trying to read it. And yes, as many people have mentioned, the beep is very soft and will not wake up your partner. Thermometer also comes with a little clear case to store it in. So overall, I've had no issues with this guy and glad I bought it.

The thermometer feels well made, the display screen is large and the backlight is good. I appreciate that it came with an extra battery, although it is coin battery operated, which is a cause for concern in a house with infants/toddlers.My main issue with this product is that it did not pair with the premom app on my phone. The bluetooth pairing feature was the main reason I got this particular BBT thermometer, so I wouldn't have to log my BBT manually every day. I have tried restarting my phone, uninstalling and reinstalling the app, logging in and logging out of the app, changing the thermometer's battery, turning my bluethooth on and off, trying to find it through the bluetooth settings, turning wifi/data off, turning wifi/data on, and just about everything else I could think of to try to make it pair, but it just won't. The bluetooth info on my phone says it is connected to yuncheng_a33 when I attempt to pair, and that connection disappears as soon as the thermometer turns off, but the pairing itself does not happen between the app and the thermometer, which leads me to believe the thermometer itself has a defect. Disappointed. I could have bought a much less expensive thermometer without the bluetooth feature, but I chose this one which doesn't have the feature I paid the extra money for.Update: I was able to exchange it, and it pairs with the app now. My one qualm is that it will only pair if the app is open and your phone is open, which is understandable but annoying.

Trying to conceive and hated documenting my basal temps. This is tied to an app and Bluetooth’s all the data with time and date information. Accurate with temps and good quality and great value for your money.

I've had and used this for about a week. It delivers one beep when you turn it on and 2 once your temp is ready. Doesn't wake my husband. The screen is backlit and I haven't had any issues with it connecting to my app as long as I open it right after taking my temp (which I don't find to be a big deal). Its super easy to use and automatically connects to your app with the date and time. I've only used it for a week so idk about the battery but I have some on hand and they're only $5 for a pack of 4 so again not a big deal. A little spendy for a BBT but for the ease I think it's worth it. I also like how big the screen is.

Great product great price nice app. Very detailed to tell what exact body temp is.

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.

I have had this product for several years and find it really easy to use and accurate for tracking temperature. Despite the cons I would still recommend for anyone tracking temperatures.Pros:- If you have the Premom app you can set the thermometer so it directly sends the readings to your phone which saves you time and having to remember the reading.- If you forget to transfer the temperature you have taken on the day, it’s fine because the thermometer can remember a few days- battery life has been excellent for me.- It is durable and value for money as it has lasted me several years so far with no issues.- The thermometer beeps once it has an accurate temperature reading.- Provides temperature to 2 decimal places.Cons:- It can take quite a while sometimes to give you a temperature reading (3-4 mins). It’s not a massive issue but at times you feel like you’re waiting ages.- I find I have to go on the pre mom app and click ‘log BBT’ to ensure the thermometer and app talk to each other. I was expecting the Bluetooth link to remain at all times and most of the times it doesn’t without this manual step. However the fact the thermometer stores temperatures for a few days in its internal memory means that I can do this every few days rather than every day which isn’t too onerous.

Heb deze thermometer aangeschaft afgelopen zomer omdat ik zwanger wilde worden en ik heb PCOS. Ik heb ook de MyOva supplement met myo-inositol geslikt om ovulatie te stimuleren. Ik dacht dat dit in combinatie met mijn temperatuur meten een goed plan zou zijn, en dat was het absoluut zeker ook! Het gebruiken van deze thermometer was heel makkelijk, meteen als ik wakker werd gewoon de temeratuur meten in bed, de bluetooth van de telefoon even aanzetten en de data gingen soepel naar de Pre-mom app :) Alles ging volgens het boekje en ik had een hele mooie chart en kon precies zien op welke dag mijn eisprong gebeurde, en kon daarna ook goed zien wanneer de ei zich implanteerde en hoe de temperatuur hoog bleef en kon ik al raden dat ik zwanger was geworden :) Ben zo zo dankbaar dat er zo'n geweldig product bestaat zoals deze thermometer, elke cent waard :)

This has honestly made my life so much easier. I used to use a non-Bluetooth bbt monitor but the struggle of putting in my bbt while I was half asleep was a pain. This is as simple as taking the bbt then going back to sleep. When I wake up, I go into the app and click the thermometer on for a second and it picks up.

Lo uso todos los días es muy práctico y cómodo

Il termometro è di ottima qualità, facile da usare e molto preciso. Mi ha aiutata davvero a monitorare meglio la temperatura basale e a capire il mio ciclo.Anche l’app è comoda per registrare i dati e seguire l’andamento nel tempo.Sono soddisfatta dell’acquisto e lo consiglio a chi cerca uno strumento semplice ma affidabile.
