Handy little App. Thanks. One suggestion: Put a 10 or 15 second delay from the time the "Start" button is pressed before counting cycles. This will allow the frequency to stabilize before starting the count.

Also, a summary page would be cool. Test time, number of beats.

Definitely worth the $0.99.

Thanks for the suggestions; I don't think the delay is necessary since it only averages over the last 20 beats. I am going to change that to a time, rather than a number of beats, since that means a wing at 100 bpm takes twice as long as one at 200 to measure. So I think I'll change it to counting the last 10 seconds or so. It calculates the standard deviation of the beat interval and announces success when that is below .02 for the sample time.

I have some other optimisation ideas to improve the performance on gliders with very flexible wings, which sometimes have a second order vibration going on at the same time.
