Ruler® 4+

Well I tried the photo measurements using a quarter it’s rather accurate on a small item. As of measuring a larger object I haven’t tried it but I hope it will work. My old phone doesn’t have AR so the AR ruler will not work but this Seems to be a good app I got the free version but watched like 3 videos to upgrade it to pro. So that’s a nice touch... you can check out other app that they have some are free so go ahead and check them out. I did and I’m happy so far.

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 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 “ruler”, 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 this app 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 this app, and never make anything again, because you WILL mess it up... badly!
THIS APP IS NOT RECOMMENDED!

This was a fairly okay ruler app. The free version used to be usable. However, the developer has recently included a timer that locks the screen and blurs the ruler after about 10 seconds, with a prompt asking you to upgrade.

The prompt can only be dismissed after the 15 second countdown. You are then granted 10 more seconds to use the app, until you are yet again met with the same prompt. This behaviour repeats as long as you use the app.

This is absolutely rubbish. If one was actually trying to sell a product, I think it would be appropriate to allow the user more time to test out the feature set. I can definitively say that this will be removed from my device.
