Simple, no instructions needed, and it's accurate. It easily displays a "touch trail" of dots showing how often the screen sensor reads finger touches and drags, plus the dots are bigger showing pressing harder on the screen. You can easily see how often the screen registers touch by speed by changing how fast you drag your finger across the screen. It's also good and finding weak or dead spots on your screen, especially where your virtual keyboard is located on your screen if you type a lot (texting, email, filling in web forms, etc.). Note: there's no UI in this app, so I hope this helps others: 1. To exit the app, use the Android "back" icon (the left arrow-like icon). If it doesn't show, drag the bottom edge of your screen upwards to make the system icons appear, including the "back" icon. 2. To clear the screen, touch and hold a single spot on the screen and the currently displayed "dot trails" will gradually disappear. 3. Remember, the harder you press, the bigger the dots appear.

I just wanted a tool to do a thing real quick. And that one did it. Didn't try to rob me, didn't try to sign my soulf to some corporation. Didn't feed me weird advertisement, in fact was not weird at all, just functional. 10 out of 10. I'm gonna look if there is a tips sistem on Google play now, gotta tip for healthy moves like that.

Good test tool but might want to make it so the line color and backround color could be changed, recommendation of the primary colors and B&W. A pixel test screen would be an additional benefit. Did not see a differance between line and dot mode. Did not use zoom. Everything else worked well and as assumed.
