Tempdrop Fertility and Ovulation Digital Thermometer Tracker – Wearable Basal Body Temperature (BBT) Monitoring Sensor and Fertility Charting App Includes Comfortable Armband (S/M – 8.5-15.5 inch)

I have an erratic sleep schedule, as I work nights as a nurse 3 days a week. I do not fall asleep or wake up at the same time on any given day. Tempdrop has been a godsend. Paired with tracking ovulation using OPKs and a fertility-friendly app (I recommend PreMom) that tracks both OPKs and Bbt in one chart, Tempdrop has been amazing. I am in my 3rd cycle utilizing it and as long as I get at least 3 hours of sleep in any 24hour stretch, it has been accurate and easy! The armband can be tightened or loosened but I always keep it a little tight so that the plate of the thermometer stays in contact with my skin at all times. It's not the most comfortable but you get used to it! It does leave a mark on your underarm but it goes away with time and doesn't bother me. You do not have to take it off if you get up to pee in the middle of the night, it recognizes when you are awake or asleep through movement, etc. The battery life says it lasts about 6 months. I'm on month 3 and I haven't had any issues so far, tbd. Pro tips: 1. Your temperatures adjust in the tempdrop app every time a new temp is added. For instance, once my temp is synced with the app, the previous 2 days of temps are adjusted so that when they are recorded on a chart (in another app -tempdrop app does not have charting yet), the progression is a steady incline or decline, so as to not look like your temps are erratic and staggered. If using a charting app -remember to adjust your previous days of temps depending on temp drop's adjustments. 2. The first 1-2 months utilizing tempdrop, the device is calibrating to your body, so the first cycle will not be accurate, but keep it going! Mine only took one month to appropriately calibrate and now works like a charm with totally appropriate temps. I even double checked with oral temping a few times.

With a traditional BBT you have to wake up at the same time every day to get an accurate reading, not with the Tempdrop! This is the whole reason I bought it, and for that, it works great! It's not uncomfortable, although did take a few nights to get used to. I had it over a year before I had to change the battery which was easy to do. I would prefer if it had a rechargeable battery that I could plug in to charge or even a small charging stand that could live on my bedside table with the Tempdrop. There's only one button, so at first I was not sure if it was recording my temp or trying to Bluetooth sync but it's easy now that I've got the hang of it. The bluetooth sync does take a minute or so, it feels like forever when I'm trying to get ready in the morning. I don't use the Tempdrop app, I just copy the reading over to Kindara. I wish it would sync with Kindara automatically, I have years of data there and I'm just not switching charting apps to use the one that comes with a new device. It is slightly overpriced, I don't think the technology (a thermometer and Bluetooth device) is that revolutionary that it should cost nearly $200 (at the time I bought it). I think the price is coming down but that's probably the main thing stopping most people from trying this. A traditional BBT thermometer is a couple of dollars at the drugstore (free with some NFP classes). Even if they lowered the cost to $30-$60 I'd bet many many more people would try it because tracking BBT is truly a pain without it. Finally, the Tempdrop team seems reluctant to advertise that it can also be used to help avoid pregnancy (as well as achieve it). However, I think if they leaned into the TTA market it would be great for the company and consumers. I would love to see this company succeed because I love the product. I love tracking my cycle/charting, it helps me know my body and feel empowered and I would love to see more women get into it. Right now, the price of the Tempdrop is exclusive but it's a great product and I think if they lowered the price and expanded the market it could be even better.

Updated Again to add: after inconsistent use for 3 years (only for a few months when I’m trying ti get pregnant) this tempdrop has been rendered completely useless. I have to open the tempdrop every time I try to use it because it won’t turn on due to the cheap chip they use no longer working when it touches the battery unless I bend the gold parts back to touch it. and then when I try to sync it, I have to do it again which destroys the sync data. Completely worthless and not worth 170 dollars. You can buy a basal thermometer for 35 dollars, and you should at this point because tempdrop now has a subscription service for their product that used to be free other than the sleep data. Really shady and shifty, and sad. Updated to add: I used to be able to see ovulation predictions without paying the premium subscription. I got pregnant and stopped using the tempdrop. Now that I’m not pregnant I am using it again and I’m sad to see you need the premium subscription for any prediction and use other than just logging the temp. I have another fertility tracker I’m interested in that I may replace this with. I had the premium subscription before just so I could use the sleep tracking aspect of the app but now that I need it for every aspect of what this product is supposed to be used for, it seems really cheap of the company to essentially sell a permanent subscription if you want any ease using their $170 product. I use this for tracking my fertility and now I pay for the subscription to track my sleep and I’m really finding a lot of value in that. I’ve used it for a little over a year and just bought the subscription recently and it is really incomplete without it, in my opinion. I find overall value is 4/5 due to high price paired with subscription. The biggest thing that helped me was buying one of those arm bands you put your phone in while you’re running and putting that on my leg at night and slipping the temp drop in there between the fabric and my skin. It has to be tight but not uncomfortable. I store the tempdrop in the pocket when not in use. Keeping the temp drop on my leg (always same leg, same spot) has made this possible for me. Otherwise it fell out every night and I’d lose it. It has been incredibly accurate and on the dot for predicting my cycle. I plan on using it to try to get pregnant soon as well.

I've been using my Tempdrop since May of 2020 and here are my thoughts: Likes: -It's very convenient--it's nice to turn it on during my normal bedtime routine and take it off the next morning as a part of my morning routine so it's easy to use in that sense. -I don't have to worry about getting up every time each morning to temp or worry that the temp may be off if I get up in the middle of the night to use the bathroom. -It's nice that the algorithm automatically adjusts the temps over a few days so you don't have to worry about major outliers for one reason or another. Dislikes: -Syncing is such a huge pain for me. Every morning it takes me multiple tries to sync (even after reading countless tips on how to get it to work well) and I feel like if I just breathe on it wrong it won't work. -I don't love the frame/band--the device constantly pops out of the frame and the band isn't particularly comfortable for me. I don't wear bras to bed so the sports-bra option isn't really good for me. -I wish I could sync it or import the data automatically to my app of choice. I know the Read Your Body app is coming but in the mean time this has been really annoying to have to sync it and then manually enter the data into another app. ********Edit as of May 2021: I'm adding a star to my original review due to the following adjustments that have been made in the last year that have improved my experience with this product: -The Read Your Body app was made available last year which made importing temps directly into a tracking app with a ton of custom options really easy. You do have to pay for a membership for the app (it is not a Tempdrop app), but I believe it's $14.99/year which isn't bad for something that makes tracking very easy. -The Tempdrop app itself has actually been redesigned and has helped a lot with the issues I had syncing my Tempdrop. I do still occasionally have issues with syncing, but it's become much more consistent with the app updates. The app still isn't quite as customizable as Read Your Body, but it does offer some options for other data input points if you don't want to download a second app.

I have been wanting to track my cycles including ovulation and when to expect my period using my basal body temp and charting for YEARS now after reading Taking Charge of Your Fertility but I just could NOT get into the habit of temping because I wake up at all different times during the week, or I’d forget, or the thermometer would be too dark to see and I was too lazy to get out of bed or I’d be in a rush in the morning and skip it. I really wanted to get serious about tracking, though, and I randomly came across the TempDrop on Amazon and omg it has CHANGED MY LIFE. It’s so so so cool to be charting now, and SO EASY. I just slip my temp drop on my arm before bed, and then hit the button in the morning to sync quickly to the app - it’s super quick and easy and I’m actually seeing when I ovulate and I know when my period is going to come - life changing!! Absolutely worth the money in my opinion. I DID have an issue where after just 1 or 1 1/2 months the TempDrop just died on me - just wouldn’t turn on anymore and I was SO upset because I expected it to last way longer than that and because I was so upset to not be able to chart after charting my first full cycle and loving how easy it was. Well I had a GREAT experience with customer service and they had me send a video/photo of me trying to turn on the TempDrop and when I showed it wasn’t working they quickly sent me a new one. I’m so SO grateful and my new one has been working just great. I’m so grateful I came across TempDrop and so grateful for the customer service being willing to help!

I’ve been using Tempdrop for a while now, and there are definitely things I love about it. It does a great job helping me estimate when my ovulation window is approaching and when my period is likely to start. For general cycle awareness, it’s super helpful and convenient. However, there are a couple of downsides worth mentioning. Tempdrop usually doesn’t confirm ovulation until 2–3 days after it actually happens, and my temperature readings aren’t always consistenly the same ovulation temp as the previous month. Because of that delay, I wouldn’t recommend relying on Tempdrop alone if you’re trying to avoid pregnancy. The confirmation comes too late to use it as your only form of fertility awareness birth control. Overall, it’s a great tool for understanding your cycle patterns, but not the best choice if you need real-time ovulation confirmation.

Really like the product, super accurate and so much easier than a thermometer in the morning. You might want to spend the money and get the newer version, the battery on mine died within a month. Luckily, I had other button batteries and it comes with a tool and instructions, super easy fix, but I wasn't expecting to change the battery so quickly.

I purchased this to help find when I am ovulating easier, and make it a lot easier to take my morning temperature on the days I either forget or I move around to much before taking my temperature and then I do not get a true reading. So far it works very well; however, the temperature is always lower than my Smart Basal Thermometer. I am not sure if where it sits on your under arm will always be cooler than under your tongue or if there is something wrong; but it has always been lower than my Smart Basal Thermometer for the past two to three months now. The arm band is comfortable however you do have to get use to it at first. But ones you are use to it then it is comfortable. The syncing is easy and really it does not take that long to sync. The app is easy to use as well; however, I wish there were more things to keep track of in the app. Furthermore, I wish it also synced with Apple Health too, and the graphs it puts out, I wish they were a little better than they are now. But all-and-all; it is still pretty good and I would purchase it again if I did not have one.
