## Description

EASY FERTILITY OVULATION TRACKER Tempdrop is a smart wearable sensor and accompanying charting app that helps women effortlessly track key fertility indicators to avoid pregnancy or increase chances to conceive. Thanks to our proprietary patented algorithms, Tempdrop will learn and pinpoint your nightly and monthly sleeping temperature patterns for the highest accuracy, helping you identify your fertility window and ovulation each cycle. Making Fertility Tracking Accessible to All Women Tempdrop makes ovulation tracking accessible to all women and offers accurate and easy digital cycle charting. The Tempdrop sensor continuously monitors sleep and temperature overnight, delivering the results you need no matter your sleep habits. Women can track their cycle confidently, even if they have irregular cycles, wake up throughout the night to breastfeed or work night shifts. It filters out variables such as poor sleep, alcohol, and travel, helping you reliably confirm ovulation and fertility. Tempdrop is HSA and FSA eligible. Tempdrop is a convenient and non-invasive alternative to oral or vaginal basal body thermometers. It is affordable when compared to wearables that measure parameters secondary to temperature. FEATURES ✔️ Easy to Use – Just wear on your arm while you sleep and sync when it’s convenient ✔️ Integrates with Tempdrop charting app and allows the freedom to use any other favorite fertility apps ✔️ Smart Technology: The Tempdrop sensor combines two algorithms, a learning algorithm, and our patented Active Temperature-Noise Cancellation (ATNC) filtering algorithm ✔️ 1-Year Warranty Choose your size: The standard armband is 5.2 to 14 inches and the large armband is 11-19.7 inches. To find out your size requirement, measure around the widest section of your bicep.

Review: I Like It But....App Needs To Be Better - 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.
Review: Love tempdrop - Before i was having trouble to get my temperature on time but with tempdrop, it's easy and very comfortable to use. Finally i can track my cycle properly and accurately.

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?**

### ⭐⭐⭐⭐⭐ Love tempdrop
*by N***K on 17 May 2022*

Before i was having trouble to get my temperature on time but with tempdrop, it's easy and very comfortable to use. Finally i can track my cycle properly and accurately.

### ⭐ Error messages
*by S***H on 30 May 2025*

Was looking forward to this. Worked for only the first 3 days but then started getting error messages. It didn't come with instructions so I had to google how to use it. First error said that data was missing due to power lapse and asked if I had removed the battery before syncing? Which I hadn't so I tried to sync it again and it said I had already tried to sync my Tempdrop today and wouldn't record my temperature. Okay, so the next night I tried again and got the same error message as the day before. I decided to return it because if it only took a week to mess up so there is no telling how many issues I will continue to have and when you are trying to use it for NFP you kinda need it to work.
