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. Review: 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. ## Features - All-in-one ovulation tracking: the portable Tempdrop sensor and the accompanying graphic app bring the complete fertility graphics solution to your smartphone.

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. ## Customer Reviews ### ⭐⭐⭐ Review *by S***H on 17 February 2026* Eh not that great. Definitely not worth over $100.

Overall, it’s a great tool for understanding your cycle patterns, but not the best choice if you need real-time ovulation confirmation. ### ⭐⭐⭐⭐⭐ Review *by J***Y on 14 December 2022* 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. ## Frequently Bought Together - Tempdrop Fertility and Ovulation Tracker –Wearable Basal Body Temperature (BBT) Monitoring Sensor and Fertility Charting App Includes Comfortable Armband (L/XL - 12.5-18.5 Inches) - Easy@Home 50 Ovulation Test Strips and 20 Pregnancy Test Strips Combo Kit, (50 LH + 20 HCG)-Package May Vary - Pre-Seed Fertility Lubricant, For Use by Couples Trying to Conceive --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/736030503-fertility-and-ovulation-tracker-portable-basal-temperature-monitoring-sensor-bbt](https://www.desertcart.hr/products/736030503-fertility-and-ovulation-tracker-portable-basal-temperature-monitoring-sensor-bbt) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-05-21*
