## 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 inal 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: the band is comfortable and works perfectly - I noticed that too many of the reviews are complaining about TempDrop itself, not the actual TD band. the armband works perfectly, and is just as comfortable as the original! TempDrop is also an amazing invention, you just gotta know to download the free app Fertility Friend to input the TD data. the Fertility Friend app will help pinpoint your ovulation date, and then makes educated guesstimates for future cycles also. just throwing this out there for anyone ttc and not sure how to best utilize the TempDrop product. best of luck y’all!

## Questions & Answers

**Q: Does this come with a warranty?**
A: Hello! We will honor a 1-year manufacturer's warranty with all Amazon purchases. If you experience an issue, please contact us at support@temp-drop.com for troubleshooting. If we determine the issue is due to a manufacturing defect, we will exchange it and cover shipping provided it falls inside the warranty window.

**Q: Anyone getting low temp readings? 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.

### ⭐⭐⭐⭐⭐ Buy from original website and get the insurance!
*by M***Y on 30 April 2021*

I love(d) my tempdrop. I tried BBT with just a thermometer for about a month before giving up due to too many inconsistencies that were out of my control: poor sleep & a puppy with a small bladder. A fertility specialist recommended the Tempdrop to me as a way to get consistent results and for TWO months it worked great. Unfortunately previously said puppy likes to chew on hard plastic items. The arm band smells just like me and she pulled it off my nightstand. It was destroyed :( Silly, stupid, sweet puppy cost me $160 for a two month product. If you are having trouble with BBT due to crazy sleep patterns buy this product - through their website. There is a $45 insurance option the covers accidental damage for 1 year. Do it! Now I'm buying this thing all over again. Product is great! Just get the insurance if you have a creature that likes to chew on expensive things.
