4 stars: Worked well on my Motorola and works differently on the iPhone, but can't use it on my new phone ,S10E. The led runs too hot and burns my finger before it can make the reading,needs to be able to dim the flash intensity.
5 stars: Extremely accurate as long as you don't move too much. I compared it with a couple of physical devices and the deviation was at most 1 to 2 heart beats per minute. Great app!
