Inaccurate Heart Rate

[Healthymamabear]

I’ve noticed while working out my heart rate is extremely inaccurate. It’s either really low or really high and the monitor on the treadmill proves that to me! Is this fixable or did i waste my money and should have purchased an Apple Watch?

Yeah, since the last update the heart rate is useless.  I’d say contact support and let them know but they’re just as useless as the heart rate.  Took them three weeks to reply to me, and in the past two weeks I’ve had a reply a week.  This has to be one of the worst companies I’ve ever had to deal with.  I thought once google brought them they would improve,  it it appears they just don’t care about the quality of updates or customer support.

My hear rate is way off with Fitbit at rest and sleep, I have verified with the hospital constantly monitoring. Haven't contacted support yet.
