Oximeter-H

Had issues so I read reviews to find info others have found helpful. Big downside manual Chinese only. Issue with display, the calender is missing double numbers. The first male is that, second is actually female. You can see this on the user's tab with pink/ blue besides name. Not sure if its only my phone galaxy Fold2 which displays like this. Take it slow, this app doesn't seem to work fast.. especially when saving the data.

Lightweight app, in the good sense. Connects quickly and displays quickly. If you keep it on, it will keep the screen on and keep recording. When you take the oximeter off your finger, the app senses it and will ask to save the data in its calendar for that person. A very useful feature - and a main purpose for having a Bluetooth oximeter - would be to make sure that it can record overnight.

The app connects to the oximeter when it is started. This will cause the minimum values to be zero when the finger isn't in the oximeter. I can have the finger in before starting the app but recording values in the calendar requires to take the finger out. It causes zero values before I can save. The minimum values become zero and the average values become falsified. A programmer could fix this problem quickly. Moreover, I need to wait about a minute for saving.
