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.

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.

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!!
