Works well, but I have just used this app to check the calibration of the engine tachometer on a boat. The enging is a 3 cylinder 4 stroke diesel. The "but" is that I had to set the upper and lower rev limit in the app within reasonable limits to stop the app fluctuating wildly between what appeared to be multiples of the actual. For example, setting the limits to 1000 and 2000 helped the app to read a reproducible 1650 rpm. I am satisfied.
Does not work consistantly This app is actually a decibel meter that assigns a numerical value -based on a algorithm- to sounds. Theoretically this should work, not accurately, but should work. Since I cannot get a consistent reading, it may just be a random number generator.
My doubt will be much clear if I will come to know under which option I can monitor 4 stroke motor cycle petrol engine RPM Thanks
Accurate + 4 star only because it doesn't keep data so I can check later on.,:( I hope that can be fixed on an update ! My mobile is an Alps i9300
Tach app - love it The best I've seen so far! This actually matched an electronic tach as well as vehicle gauges. Someone finally nailed it.
Best app and BEST support!!! Developer responded to email in literally three minutes!!! (Google messed up and I was unable to checkout, there is absolutely nothing wrong with the app!) Just Excellent!!!!!!!!!
