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.

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.

Helpful for tracking cycles, but not ideal for avoiding pregnancy
Iโve 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, itโs super helpful and convenient. However, there are a couple of downsides worth mentioning. Tempdrop usually doesnโt confirm ovulation until 2โ3 days after it actually happens, and my temperature readings arenโt always consistenly the same ovulation temp as the previous month. Because of that delay, I wouldnโt recommend relying on Tempdrop alone if youโre trying to avoid pregnancy. The confirmation comes too late to use it as your only form of fertility awareness birth control. Overall, itโs a great tool for understanding your cycle patterns, but not the best choice if you need real-time ovulation confirmation.

Works great, not super comfy
Life changing for fertility tracking! So much easier than taking temps every morning. I do wish it wasnโt drop shaped, since it kind of stabs into my arm at some angles when Iโm wearing it. Took a few weeks to get used to, now Iโm not as bothered by it. Itโs kind of annoying that it doesnโt sync automatically. I donโt keep my phone in my bedroom, so I have to make sure to remember to sync it every day or two. Overall worth it!

Error messages
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.

LOVE
Iโve been using my Tempdrop for a few weeks now and I love it. I have PCOS and an erratic sleep schedule, so trying to temp every morning is impossible. With this Iโm able to put it on every night and chart my temps each day, looking for my temp spike to figure out where I am in my cycle. The Facebook group for this product is also extremely helpful :)

Buy from original website and get the insurance!
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.

Worth it, might be pricy, but good
Totally neat to not have to take a thermometer in the morning for temp and this thing is super comfy and super easy to use. With al electronics there can be a problem, which is why i am not giving it a 5. But it is worth a try for sure
