How to return heartrate? about atheartrate HOT 4 OPEN

The bpm value is way too high. Is that suppose to be my heartrrate? When compared to other apps, it seems wrong.

Heart rate needs to be averaged over a period of time. You are not able to get reliable results until the signal has stabilized. This is common in signal processing. You will want to make sure you take readings until the heart rate stabilizes. In the code, I am taking it for 30 seconds but you could just wait until it stabilizes after 10 seconds or so. Note that this depends on the user keeping their finger directly over the camera, without pressing too hard (as this constricts blood flow and can cause different results) or moving too much (as this introduces additional noise in the signal).

How high is "way too high"? Heart rate comparison is a little tricky because it is so variable. Unless your recordings are happening at the same time, it is not a fair comparison.

so in this line of code: NSLog(@"Value is %i", bpm);

bpm at 10 seconds is 70
bpm at 30 seconds is 100

My resting bpm is 68-70

Am I even using the right variable/function to get the bpm?

@lehn0058 I am taking heartbeat for 30 seconds, I am getting value in following method
- (void)heartRateUpdate:(int)bpm atTime:(int)seconds;
When this 30 seconds is completed - (void)heartRateEnd , how to show the final value ? Is it last value from following method
- (void)heartRateUpdate:(int)bpm atTime:(int)seconds; OR
average of all values returned in following method
- (void)heartRateUpdate:(int)bpm atTime:(int)seconds;
