Review: A Night Nurse's Best Friend for fertility tracking! - 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.
Review: The only way to track your BBT without waking up at the same time every day as far as I know... - 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.

## Questions & Answers

**Q: Does this come with a warranty?**
A: Hello! We will honor a 1-year manufacturer's warranty with all Amazon purchases. If you experience an issue, please contact us at support@temp-drop.com for troubleshooting. If we determine the issue is due to a manufacturing defect, we will exchange it and cover shipping provided it falls inside the warranty window.

**Q: Anyone getting low temp readings? I am getting 95/96 whichs below my norm readings of 98+..**
A: Hi there. Tempdrop can read in a different range to traditional thermometers but please email support@temp-drop.com so that we can run a review for you to ensure your sensor is working correctly. Thanks!

**Q: Do you have to sync every day or can you go a few days without?**
A: It holds your sleep data for 3 days I believe but I always sync it the next morning to keep my charts accurate

**Q: Where on your arm do you wear the band? Can you wear it on your wrist like a watch?**
A: No. The band is worn around your upper arm with the monitor on your inner arm, close to your armpit. It will not determine temperatures correctly if worn on your wrist.

### ⭐⭐⭐⭐⭐ I AM FINALLY ACCURATELY TRACKING MY PERIODS!!!
*by L***Y on February 2, 2022*

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!
