Don't get this app
Doesn't work as advertised. Benchmarked against built in tach. Did not match at idle or under throttle. Always showed weak signal even when held against engine case. Tried on parallel twin 4-stroke and single cylinder 2-stroke
Not worth it if it was free.
App does not work different rpm every time the app is opened under identical conditions and the numbers are not remotely close.
Don’t buy. Does Not Work.
I tried everything to get this app to work, but it kept saying to hold it closer. I couldn’t have held it any closer. Simply doesn’t work. Luckily it’s not very expensive, but I should have thought to check the reviews before wasting a couple bucks 😔
Didn’t work as intended
The app couldn’t pick up the sound of my Yamaha xvs650, despite being repetitive and loud. Put it right up to the exhaust at one point and still no dice.
Complete rubbish
Don’t waste one penny on this, complete waste of time. It’s just a rip off. I got the same RPMs when it was next to the engine, and when the engine was completely turned off, and in a very quiet environment.
App Does Not Work
This gauge does not work. Can’t tell the difference between voices, background sound or motors.
Doesnt work on mr DR650
Maybe it doesnt work because its a single cylinder but I tried putting the phone next to the engine, next to the exhaust, on the seat, and I always get a message telling me phone is not close enough to the source. The concept is great, but the app just didn’t work for me.
Doesn’t Work As advertised
This app simply does not work as advertised. Even though it’s cheap, I wouldn’t recommend it! I tried using this app to measure the idle RPM’s on my single cylinder motorcycle so I can set the air/fuel screw correctly. No matter what settings I change it says that my bike is running around 5000+ RPMs at idle!! That’s simply not possible seeing my bike red lines at 8000 RPM! The developer commented on my last review saying they fixed some few things that should help but it did not!! I still feel like I completely wasted of money on this app because IT DOES NOT WORK CORRECTLY!!!!
PLEASE FIX THIS APP SO IT WIRKS CORRECTLY!!!!!!!!!!!!!

Thanks for your feedback. We updated and improved the algorithm in the new version. Maybe it helps to solve your problems with the app.
No adjustments for cylinders
I was trying to use this for a motorcycle. There is no way to adjust for number of cylinders to get an accurate number. My assumption is it was counting each sound to get the number so I divided by two to get 1200 rpm at idle as it was reading 2400.

Thanks for the feedback. We added a setting for accounting for the harmonic order. I hope that helps with your problem.
Seems to apply a correction factor?
I like the function of this app but it seems to assume I am measuring a 4 cylinder engine and the output is divided by 4. Can you make a setting to adjust this?
Actually I am trying to measure the vibration of some consumer electronics so I want 1:1 output.

Thank you for your feedback. We added a setting for accounting for the harmonic order. That should help for the 4 cylinder problem. For the consumer electronics problem: do you need to have the dominant vibration frequency?
