Multipoint test is almost worthless.
It works, but because the developer just uses stupid red circles to show the touches, after a few touches you can not possibly see the new vs. the old circles from each other. They just blend in and overlap and the test itself is utterly useless. I am trying to diagnose a glitchy screen that gives me spurious ghost multi touches. But this app just gives me a bunch of red circles. At a minimum alternate your color each time you see a touch. Make it so they don’t overlap so badly. And let me test the entire area of my screen. Also design it so that it highlights ghost touches and I can see if it’s counting a double touch vs. triple, vs. quadruple touch. Put some actual thought into it. This app looks like it’s version 1.0 and is a long way from being a professional grade tool as far as the touchscreen tests go. I wish I could get my money back.
