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.

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!

Update - March 2023: Sharing for anyone else frustrated with their armbands and looking for an almost-free solution. For the last several months, I've been using my TempDrop with a MacGyver'd armband made simply by wrapping 3" wide stretchy self-adhesive bandage around my arm. After turning the TempDrop on, I slide it between my arm and my "armband", and the TempDrop stays perfectly snug without me losing feeling in my fingers in the middle of the night. My makeshift armband is multi-use and way more comfortable than the TempDrop armband was before it broke... Also, I noticed they are now offering different sized armbands. This was not available when I purchased my TempDrop. I hope the new armbands are better than the one that came with mine, but just like the premium features of the app, I refuse to spend more money to use this expensive device. And, why should we when the calendar and graphing features in other 3rd party apps, like PreMom, are free? I still like the functionality of the TempDrop, as I mentioned in my original review. In fact, my temps from yesterday and this morning prompted me to take a pregnancy test -- and it's POSITIVE!!! ................................... I really like the concept of the TempDrop. I tried a digital traditional style BBT thermometer, but after waking me up, my dogs didn't like it when I continued to lay there for 1-2 minutes instead of taking them outside or giving them breakfast. They would get antsy, and then start to wake my husband up. The convenience factor of the TempDrop is worth the cost to me. With TempDrop, my dogs wake me up, and I don't even think about getting my BTT. Most days, they're waking me up between 3:30-4:30AM, and I go back to bed. So, for me, the TempDrop is better than taking my BBT in the normal ways. However, the lacy armband while cute, is TOO SMALL. I'm not that big of a girl, but I had to completely let out the arm band, and sometimes it still feels like a blood pressure cuff squeezing the life out of my arm. I suppose that helps it to not move, but I hate the "ghost feel" that lingers on my arm for hours into the day. The sensor has TWICE not recorded or lost the info. Maybe I did something wrong, but, IDTS... And, my last issue is more with the TempDrop company and their app. For such an expensive little gadget, the "premium" features in the app should be standard and free. I know, I know, subscriptions are a gimmick, I mean method, for continued streams of income... I get it. It's ridiculous and I hate it, but maybe after dropping nearly $200 on their product, they could or should offer at least one year of free Premium. Maybe at the end of that year I would want to subscribe because I really like the extras that aren't provided in the free version. As it is now, I am not a subscriber, and I won't subscribe. In conclusion, I like the TempDrop. I would buy a new one if something tragic happened to it, but I will not subscribe to the app.

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 love my tempdrop!!! With a toddler who wakes up at odd hours, a job that could have me up all night long, and unpredictable sleep, I needed something that could help me with my temps during my cycle. Not only does this help me, but it's also incredibly easy to use. You put it on your arm, turn it on and go to sleep. In the morning you take it off and sync the data to your app. That's all. Seriously. No more setting my alarm for 7 am to make sure I take my temp. No more missing temps because I worked all night or because I didn't get 3 consecutive hours of sleep (tempdrop needs at least 3 hours of sleep, but it doesn't need to be consecutive). My first cycle with tempdrop is really really smooth and easy to read, with a clear shift and a very clear LP drop. I was even able to put in my cup before my period started thanks to a very clear LP dip. I'm impressed! I'm on my second cycle and it's so easy to read! If I could say ONE bad thing, it's that the armband is uncomfortable. I have it working well now, but I'm hoping they can eventually fix this problem. EDIT: I found that if I use the pink ribbon in the Armband vs the lace, it fit better! Going on 6 months and I'll never chart with a regular BBT again!!

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.

Honestly I am really unimpressed with this device. First impression - cheap plastic frame. unappealing, cheap and annoying to use band, and worst of all device never really seems secure in it's frame and often falls out when I'm trying to put the band on and off. I figured, "well if it tracks temp accurately then I can deal with that" - get past all the poor aesthetics and annoyances of constantly putting the device back in its frame. It DID work well for the first week!! Then, for some reason it stopped being able to pick up my data - the majority of the time I try to sync in the morning, I get an error message that there's "not enough data". I've read the manual, the facebook group, watched videos, researched other pages - I'm CERTAIN I'm wearing it in the correct spot in the correct way and I have it tight enough that it leaves a (very light) mark on my arm when I remove it. It doesnt seem to move at all through the night, and I fortunately sleep through the night without an issue so there is no reason I can see of why it cant pick up "enough data". Here's the real kicker. 6 weeks after getting it, the frame broke and pin flew out and I couldn't find it. The company won't replace the pins telling you that you need to go to a watch repair and get your own! Seriously, after spending almost $200 for this low quality product, they dont even offer replacements for their own cheap goods. Any of these things individually I could overlook as maybe a one-off or some kind of bug happening with my device. But taken all together ... I'm super unimpressed. It's 2020, there are no shortage of GOOD band options and materials so it should not be difficult or much more expensive to have a nicer frame that the device actually stays in and a decent band instead of this weird thing that so many people have trouble with. (I've had several smartwatches for $200 and under, and they all were sooo much better than this, I don't understand why tempdrop went with such a low quality band and frame option for what's likely decent technology.(tech- It seems like most people dont have the data retrieval problem I'm having so maybe thats something wrong with mine, so if the tech is good why not put it in more user-friendly frame and band.) For the price point, I'm pretty sure most people buying it would pay another $10-$20 for it to actually be a nice product to use instead of something that falls apart every time you try. I returned it and am going back to manual temp reading because it was way less frustrating than dealing with this thing each night and morning ;) Hoping for future product improvements and I'll be back.
