HeartRate.Tech's answer:
Breathing exercises
Very nice, easy to operate. Doesn't let your finger burn from camera flash like other apps. Does quick BP readings when access to appropriate medical equipment is constrained.
Using it on my iPhone (but it has also Android version, I know) for almost 1 year. In my experience, this app is quite accurate. I tested it with my beurer pulseoximeter while struggling with covid and measurements were just like the same, so I was impressed.
