Engine RPM for
Android or iPhone
- Engine RPM is an app that listens to the sound
produced by a running engine and calculates the RPM of that engine
from the sound. It is available for on iPhone
and on Android. Engine RPM uses the
same signal processing technology used in our piano and organ tuning
products to extract the pitch of the running engine and then convert
that pitch to an RPM.
