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.

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.

Great, but have extra batteries handy
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.
