Ratings and reviews

Doesn't work at all. Tested on motorbike, SUV, and car. Changed settings as applicable but gauge was clearly way off. update in response to developer- nope. Reinstalled to try again after they "improved" the app. still doesnt work, at all. totally useless. Also plays offensive ads that you can't close or mute. App itself seems like some kind of scam.

absolutely no idea idea how to use the app. it let's you set the type of motor but then does absolutely nothing- no options controls or anything. there is an rpm meter that moved from 1k to 5k but is not responsive to throttle at all. I was testing with a loud motorcycle and paid for the app. don't waste your time. Yes chaned settings to 1 cyl 4 stroke. RPM went from 1k to 5k.

App doesn't work. No sound rpm shows above 1k and bounces. Testing with my voice and various pitches it does read different rpm though it couldn't be trusted. Tested on my snow blower which I know is running high registered very low 2.5k rpm and sometimes bounced to various rpm. With phone right by muffler, registered nothing. App can't be trusted for anything accurate.
