Engine RPM

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!

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.

1- Read all the help pages beforehand; it’ll take you about 5-10 minutes but well worth it. 2- I used to set idle on a 2 stroke fuel injected motorcycle where the idle is critical: too high and the bike runs too lean, too low and it bogs down in low RPM starts. 3- At first I had it set up to sample every 3 seconds. That was too long. So I cut to 3/4 of a second and it was less of a hassle. I was able to guesstimate the current RPM’s at 1500, (actual was closer to 1700), so I set up the software that way, kept making small adjustments on idle screw until I got it just right. 4- Logging the RPMs and times was a nice feature. 5- to get a 5 star price needs to come down materially or ease of use must improve significantly. Overall I’m happy with this given the alternatives.
