Engine RPM is a Utilities app by Real-Time Specialties. 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.

APK (Android Package Kit) files are the raw files of an Android app. Learn how to install engine-rpm.apk file on your phone in 4 Simple Steps:
Yes. We provide some of the safest Apk download mirrors for getting the Engine RPM apk.
1. 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.
2. 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.
3. The analysis requires a clear sound from the engine without excessive interference from extraneous sounds.
4. 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.
5. 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.
6. A real-time graph of the autocorrelation graph is displayed to help in troubleshooting and adjusting the expected RPM range.
7. Do not expect to read the RPM of an engine while other things are making too much noise at the same time.
8. To use the app you must set an expected RPM range to guide the analysis algorithms to the correct RPM.
9. Measure the RPM of an engine by analyzing the sound it makes.
10. 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).
11. It cannot read the RPM of an engine that is rapidly accelerating.

I just want my 9 dollars back. Sick of trying to get this to work.
Was able to dial in my snowblower RPMs no problem. I do think the app should have the cycle/number of cylinders option right on the Home Screen, I think that would help out. Also, would be nice if it had good enough response times to react to transient surges, really it’s only useful for steady RPM values. But overall, did what I needed for much cheaper than a small engine tach.
An indispensable shop tool
The documentation explains exactly how this works, and what the limitations are. There are some big advantages too: low cost and no need to touch the engine. I used this to tune my old rototiller engine. It took some experimentation on where to position my phone near the engine, but I was able to get a strong signal and confirm max RPM and idle RPM.
This was a little more expensive that I would have liked but once I used it I would say it’s defiantly useful. Used it to check low and high speed of my lawnmowers and it’s right on. Just slide around the hint rpm as it’s running and it finds the speed right away. It’s also cool that you can also see the audio waveform. The app doesn’t look to fancy but as long as it keeps working with future iOS updates I’ll be happy.
