Like smaart but easy to use

Inexpensive alternative to smaart. Very accurate and easy to use.
Thank you very much for this peace of software!
One request: the trash bins on the right side are not really reachable with fingers on IPhone and IPad versions. Maybe move them a bit to the left?
And a full screen mode for the graph in IPhone version would be really great.

Nearly Perfect tool for the job

Love the software. Support the dev! Like Smaart lite, but so cheap. I get results w this so quickly and the IR delay finder is eerily accurate
