Engine RPM

I want my 8€ back

Per quello che costa e' quasi una truffa! Ho provato con la mia harley e ho seguito anche il manuale online. Niente, non riconosce in modo corretto il suono e dà valori sbagliati. Buttate fuori dalla finestra i soldi.

I have a harley very distinct sound but the app just doesn't read right also tried with the manual just wasted 7 €

The Tiny Tach tachometer I’ve been using in my small engine work wasn’t extremely expensive, but it’s finicky and difficult to use when I’m tuning something like a chainsaw. This app, after a couple minutes glossing over the instructions, was almost intuitive to get to function. It will be really nice to be able to set this down and have both hands free to operate the throttle and adjust carburetor settings on equipment now. Large, easy to see display and controls plus other features I haven’t even gotten to will make my work SO much easier! Thanks guys, for all your hard work. I’m totally happy with the price!

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.

This app worked very well to help me set the idle on my Royal Enfield 500cc single cylinder motorcycle. It picked up the “thump” of the engine immediately thus allowing me to fine tune the engine’s RPM to specification. 100% pleased!
