DO NOT WASTE YOUR TIME

This is the worst app Ive ever used. Not only do the ads interrupt your heart rate test but then the 5 mandatory seconds is really 20 seconds, not done yet b/c trying to close it takes at least 30-40 taps! After pissing you off enough to pay to skip ads IT THEN DOUBLE BILLS YOU! ZERO STARS IF I COULD. Will never use these peoples apps EVER again.
