What is Engine RPM? Description of Engine RPM 1583 chars
Measure the RPM of an engine by analyzing the sound it makes. Engine RPM listens to the sound of a running engine and uses advanced signal processing algorithms to extract the frequency of that sound and calculate the RPM.
This app is primarily for setup and diagnostics of engines. After setting the the number of cylinders and whether the engine is a 2-stroke or 4-stroke engine, the app can work with any internal combustion engine, from diesel tractors to aircraft engines to motorcycles to chainsaws. To use the app you must set an expected RPM range to guide the analysis algorithms to the correct RPM. A real-time graph of the autocorrelation graph is displayed to help in troubleshooting and adjusting the expected RPM range.
The analysis requires a clear sound from the engine without excessive interference from extraneous sounds. Do not expect to read the RPM of an engine while other things are making too much noise at the same time. The analysis also requires that the RPM be stable. It cannot read the RPM of an engine that is rapidly accelerating. For this reason, and because of the need for adjusting the expected RPM range, this app should not be considered a drop-in replacement for an operational tachometer.
Setup options include update periods from 93 milliseconds to 1.5 seconds, one to 12 cylinders, 2-stroke or 4-stroke, low-pass filtering, and signal clipping. The overall RPM range is 400 to 90,000 RPM (although at any one time, the operational range is typically +/- 30% around a nominal expected RPM). Precision is usually about +/- 10 RPM.

Engine RPM Pros
✓ Great App for any engine tuningI have to admit that this is a great app for the iOS platform. I've used it to track engine rpm from my RC helicopter to RC planes to RC nitro and gas cars. It's a great app to use for so many other applications. I highly recommend this app. Works perfectly with iOS 7..Version: 2.1
✓ It does work and does provide RPMOnce you figure out how to configure the app for your engine it works. It's not perfect tends to bounce around could use an output filter. You have to play around with this app to get it working right. It's not perfect but I was able adjust my carb to 3600 rpm ie snow blower..Version: 2.1
✓ Engine RPM Positive ReviewsEngine RPM Cons
✗ Expensive app that doesn't workVERY disappointed in this expensive app. I have previously used an RPM from sound app on a PC and it worked quite well. This one didn't have a clue. Used it in a single engine airplane (recommended use in the app description) and it didn't have a clue. Giving it a hint didn't help at all. Actual RPM was about 2,500 and it would jump from many thousands to a few hundred. And back again. Best use would be as a random number generator. Save your money. Guess that's what I get for being an early adopter..Version: 0
✗ Waste of moneyEven cars on street interferes with readings - completely useless and overpriced.Version: 2.0
