Ok, starting with the fact that this thing is not even that accurate, and even to use it for more than 5 seconds will cost me 5 dollars?!
What the hell? Also, just seeing that this trash “app” actually is only free when you use it for 3 seconds is completely outrageous! It’s not even worth your... Show more time and money, and I have no idea why there are so many good reviews on this thing. I first downloaded it just to use for homework, but after opening it for 2 seconds, a purchase ad came on, and I pressed “cancel”. Then, after 3 seconds of using the so-called “this app”, a message popped up: measure time “exceeded”. Buy the upgrade to cancel this limit or wait 20 seconds. EXCUSE ME? I used it for 3 seconds! How did I exceed any limit? Just thinking about this freaking app makes me want to hurl. How did Ruler even get 2-star ratings? After 30 seconds, I just deleted this stupid waste of my time. And developer, if you are reading this, go stick your head in a trash can, delete Ruler, and never make anything again, because you WILL mess it up... badly!
Ruler IS NOT RECOMMENDED!
