“I decided to test it out and bought a thermometer after I tried the app. The first time around, I thought, ‘Okay, now for the second time.’ I went to CVS, sat in the store, and used the app again. The readings were still around the same, and yes, I had people staring at me like I was crazy.
Then I bought a thermometer, used it, and the readings were similar to the ones the app gave me. I tried the app right after, and when I say it worked, I mean IT WORKED!!”

“This app is amazing! It lets you keep track of your heart rate and your breathing rate. Plus, it shows you if you have a fever or not. Right now, I am sick, and I do not have a thermometer. This app is completely free! You can buy some things in the app, but other than that, it's free! The last temperature I had was 102.2°F, so now I know that I have a bit of a high temperature. So, please, this is an amazing app. If you don't know if you have a fever, download this app. It helps so much.”

“This is a super good app. If you don't have a thermometer, you can literally just use this app. It's so good because you can use it while you're at a store, at school, on the bus—really anywhere you go. If you feel hot and nauseous or have any COVID-19 symptoms, you can easily check your temperature to see if you have a fever or a cold. I totally recommend this app. You should get it! I would love for you to get it. If you love this app as much as I do, please tell me in the comments.”
