If you have an Android based smartphone, you can download the free "RPM Gauge" application from Google Play...exact same acoustically measured tach as with a the Hobbyco and similar tachometers...

How does that Andoid tach app work? Does it have to be adjusted for 4 stroke, 2 stroke.number of cyls. etc? Will it work on car engines? What part of the phone do you point at what part of the engine? I could use something like that. My problem will be figureing out how to download and use an app. Never done it and I am tech impaired!

It works with microphone of mobil phone. No need to point microphone but need to be close to propeller. It can be adjusted on settings for two stroke. Here is app:

Thanks Levent...got app installed..set parameters. But it flashes numbers on screen with nothing running. Is that normal until engine runs? Or should it all be zeros?
Sorry for the highjack...but this caught my eye as usefull!

Number flashing is normal. Flashing stops while engine rpm reading.

Cool! I'll test it out on my wifes Hemi !. No airplane engine running in basement!

Is it posible to tach the vidéo ??
