Ratings and reviews

So my honda generator was being a jerk...I knew it was the automatic idle. Too high and it would surge, too low and it would stall. Had to find that 3500rpm sweet spot, but how? I'm not a mechanic so don't have the tools, maybe I can download something. So I downloaded this app, and no $h¡t my generator is running better than it has been for a year! Great app!!! I can only say sorry you can't figure it out, to the people who can't figure it out

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.

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.
