1. 5/5So far I’m Impressed

   It took me a minute to figure out how it all worked. I couldn’t quite get the finger placement on the camera and flash for heart rate right at first and I definitely couldn’t understand how heart rate, the amount of inhales I took, and how holding my i phone 8 with my case on or off could possibly read my temperature. Surprisingly, it was pretty dang accurate compared with my thermometer. My thermometer read 97.5 at one point and the app said 97.4 like very accurate. I was concerned my thermometer wasn’t accurate but it’s been on par with this app so I’m becoming convinced. I am sick, I am afraid it’s going to turn into pneumonia and I keep checking my temp which has been oddly low, like 97.5 that’s nothing I’ve ever experienced so I assumed it was wrong but I kept checking the app and the thermometer and it was consistent. I have a baseline temp of around 99 so I run high normally. My resting heart rate is also high normally due to medications I’m on so I adjusted my normal rates. I’m assuming establishing your baseline info helps as well but I don’t know. I also did it with the case on and off and I kept getting good results. How does this work? I also haven’t been charged and am not in a pending trial just because I downloaded the app according to my account. I checked my subscription status and account details and I see where I downloaded it for 0 dollars and it shows nothing pending so I think some people are definitely doing some things wrong. I will be getting a better thermometer and rechecking this again along with seeing if I’m ever suddenly charged with a fee to my account, but so far so good. If this works, I’m so happy to have this free info to be able to track, that I will eventually upgrade to the oxygen given my health issues. Also I have maybe reviewed 5 things in my life because I hate reviewing things. When it’s potentially a very good thing for me, that I think could be good for others that may be using it wrong, I review. I would want someone to do the same for me. I’m pushing 50 and I don’t always get tech to work for me until I ask my kid what the heck I’m doing wrong. Anyway thank you!

2. 1/5Total scam - updated

   Go ahead on app support to see how much of a scam this app is. It takes you to a screen that talks about how great they are but with zero support. No contact info. No help. They responded to my post to contact them and left no contact info and they have no way to contact them through support. That should tell everyone how much of a scam this app is. I worked in the medical field and you are taught to always be honest with your patient because false information can be very dangerous. Well this is false information. It gives you numbers based on total guesswork. It’s sick and wrong that they take money from people that have health problems. They should shut this app down and refund every person that got scammed. I paid the $5 for a weeks use because I needed to know a temperature. It doesn’t measure your temp in any way. It asks you for your pulse and breaths per minute then takes a calculated guess as to what your temp is. That’s not taking your temperature. That’s guess work and a total scam. Not only did I waste money on something that gave false information on what it does but I wasted time when I could have gone to the store for a thermometer. People like this that make false claims about medical help are some of the lowest on the planet. I don’t know how they can sleep at night knowing they are scamming sick people.

3. 5/5Life saver

   One night I was lying down and was feeling off and had a headache was dizzy and nauseous and unreasonably hot. I had not thermometer in hand because ours broke so I quickly looked up some apps that could possibly track my temp I was skeptical at first wondering how I could trust AI to determine my temp with no proof of actual detected or something that can measure my temperature but as soon as I got into the app it explained how it worked which relived me to an extent knowing there was proof it could possibly work And with all the extra steps it took to ensure the best quality of my experience I was far from skeptical by the end thankfully I took some medicine to calm my mild fever down and was fine. This will now become a part of my daily routine!

4. 1/5SCAM

   this app doesn’t do anything that it implies. First of all, even as scammers they obviously weren’t smart enough to learn how the human body works. They don’t allow you to put your actual heart rate if it’s too high. My heart rate was 123 but every time I tried to enter my heart rate, it kept telling me to enter my correct heart rate. 123 was my correct heart rate. If anything it almost went higher because of how much stress this app causes. If your actually worried about your health, please don’t deal with these scammers. They are just trying to use your disabilities to make themselves money while just making the situation worse. On top of that, it doesn’t actually measure your heart rate using your finger. It just takes a guess which most of the time will be the exact same thing no matter how or when you do it, which is why I tried entering my heart rate manually since I checked it myself, but obviously they don’t allow you to enter your real heart rate because they don’t know how to determine what it means.

5. 5/5Extremely useful!

   This app is extremely helpful for keeping track of most everything that I need to know about what’s happening with my health. It truly helps keep track of my health symptoms throughout the day so I can find patterns and make adjustments to my daily routine in order to better my overall future health. I also love that it communicates with the Apple Health app. It’s very user friendly and easy to use. My only complaint is when I manually enter my body temperature on my Apple Watch, it doesn’t actually record it in the app. Maybe it’s a glitch or something… It DOES, however, keep track of my wrist temperature whenever I’m wearing my watch, so that’s another helpful feature. It also keeps track of my heart rate and blood oxygen levels (newer models of the Apple Watch have this feature) throughout the day and night, which is VERY important for me to keep track of due to my current health status. In summary, it’s an excellent app for tracking symptoms in one place, so you can easily find patterns and share with your doctors and caregivers.
