Easy@HomeSmart Basal Thermometer, Large Screen and Backlit, FSA Eligible, Period Tracker with Premom(iOS & Android) - Auto BBT Sync, Charting, Coverline & Accurate Fertility Prediction EBT-300

I’ve been using the Easy@Home Basal Body Temperature (BBT) Thermometer as part of my fertility tracking routine, and it has exceeded my expectations in both performance and reliability.Accurate and Reliable: This thermometer measures to the hundredth of a degree (e.g., 97.68°F), which is exactly what you need for fertility tracking and ovulation prediction. I’ve found the readings to be consistent day after day, which helps make my fertility charting more precise and trustworthy.User-Friendly Design: It’s very straightforward to use—just turn it on, place it under your tongue, and wait for the beep. It takes about 90 seconds to get a reading, which is pretty standard for basal thermometers, and well worth the wait for the accuracy it provides.Memory Recall and Display: One of the features I appreciate most is the memory function—it automatically stores your last temperature, which is great if you’re groggy in the morning and forget to write it down right away. The screen is easy to read, though I do wish it had a backlight for dark mornings.Silent Option & Portability: There’s a discreet beep when the temperature is ready, but it’s not overly loud. The thermometer is lightweight, compact, and comes with a clear cap to protect it during travel—perfect for taking it on the go.Perfect Companion for the Premom App: If you’re using the Premom app, this thermometer syncs up perfectly with it. While this model doesn’t connect via Bluetooth, it’s designed to integrate seamlessly with manual entry, and the app gives you a complete picture of your cycle.Final Verdict: For the price and the features, the Easy@Home BBT Thermometer is one of the best options out there for anyone using natural family planning, trying to conceive, or wanting to get more in tune with their body. It’s affordable, dependable, and does exactly what it promises.

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!

Easy to use

The thermometer is very accurate to the thousandth (.01) place and the pre-mom app is very easy to use even without subscription.My biggest complaint is that this thermometer takes so long to read. Like an extra two-three minutes laying in bed after waking just for it to read & then another minute to reconnect it with my phone. It doesn’t seem to stay paired with my phone, so I’m always having to reconnect it every morning for the temperature to load to the app.I do like that the previous temperature shows up the next time I turn it on.

Okay you need to allow Bluetooth to access the Premom app if you want to pair the Bluetooth.

Bought this together with the ovulation tests. This confirms that I have ovulated. Together with the ovulation tests, thses products are amazing. I can't be happier.

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.
