Last fall I posted about the Android app I developed to measure the RPM of an engine from the sound. Thanks again to those of you who volunteered to test it for me. But now I have incorporated the improvements in the signal processing algorithms that I developed for that app into my existing iPhone app, for those of you who have iPhones. If you would like to help me by testing this acoustic tachometer against your aircraft or lawnmowers or whatever, please message me privately. Unlike the Android app, the testing of pre-released iPhone apps is not done with promo codes but with the free Apple app called "TestFlight". I will supply details to those who contact me. Thanks in advance.

Hi, Robert. How's Hopkins? Lived in Burnsville, 1992/93.
How did that Android app work out? Not that my engine will be back together soon... :)

Hopkins is great, though we went back to snow today. I know Burnsville well, overlooking the beautiful Minnesota River.

The Android version worked well. And now I want to bring the iPhone version up to date with the same improvements I developed for Android. I have not updated the iPhone version in four years, so it is overdue for an update.
