Very accurate. Helped me conceive on my second month trying. Data is very accurate. Love the digital feature. And battery life is good. First time User friendly

I've purchased the thermometer to start tracking my basil body temperature. It was super easy to connect to my app, and that is the main reason that I picked this thermometer over others. Not having to manually enter the temperature each morning has encouraged me to continue using it for the years.every morning when I wake up first thing I do is take my temperature. I find that it is quite accurate and reliable in temping. The app also puts your temperatures onto a graph that you can look at to see the changes throughout your cycle. The app itself is super easy to use and has other great features even on the free version. 

Although my intention to use this thermometer in the future is to get pregnant right now I’m really loving it for being able to track my cycle. My only issue with this thermometer (I got the new one that just seemed super simple, no frills) is that you still hear beep in the morning and when you’re trying to do it early when your partner is sleeping before you can even get up out of bed it does it get a little annoying. But the fact that it completely syncs with the app is so easy, all you have to do every few days / weeks is open your app and open your thermometer at the same time and it will sync. You do have to pay for additional storage in the app for it to track all your cycles but that’s just a part of it. I’d rather not lose the data.
