Threw all my historical data away after a crash. Edit: after contacting the developer, he fixed the bug within a week! Thanks dude :) Back to 5 stars.
Way too touchy... Gives different readings that are way off from other apps and devices... Not good.
Good app with lots of potential. The history graphs don't work for me, they are flat and all look the same. The heart rate range from the calculator is not used for anything either.
I have a missed or extra beat and the graph shows it.
Either I have funny fingers or this is a toy monitor; when my heart rate is 100 it reads 40
Yep a defo keep best one yet ! And easy to read ..well done : ) 5 stars from us :))
Added new measurement mode
Most Precise Heart Rate Monitor Ever + Unlimited Measurements and Records.
