Tempdrop Fertility and Ovulation Tracker: Portable Basal Temperature Monitoring Sensor (BBT) and Fertility Graphics (Large - 28-50cm)

Eh not that great. Definitely not worth over $100. You have to sync it every few days which is annoying otherwise the memory fills up. It doesn't automatically sync either - you have to open an app on your phone to do it. It's a bit annoying to put on and remember to turn it on before falling asleep. Honestly it's pretty low tech.

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.

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.

Tempdrop was great for tracking temperature and cycle; however the sensor must be extremely delicate. It only survived about two years and died after a simple careful battery change. I only wear it half the month, so don't expect longevity for this product if you wear it daily. Warranty is just a year but they offer extended warranty for another year if you purchase it. They did offer me discount but I am still disappointed it's not better made.

Life changing for fertility tracking! So much easier than taking temps every morning. I do wish it wasn’t drop shaped, since it kind of stabs into my arm at some angles when I’m wearing it. Took a few weeks to get used to, now I’m not as bothered by it. It’s kind of annoying that it doesn’t sync automatically. I don’t keep my phone in my bedroom, so I have to make sure to remember to sync it every day or two. Overall worth it!
