Pretty good

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.

Worst app I have ever seen

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!

Cash grab

There is a set amount of SECONDS that you can measure for before the ruler becomes pixelated and you are prompted to upgrade or wait 10 seconds before you can continue measuring. This repeats over and over. 10-15 secs of measuring and 10 secs of a pixelated screen prompting you to upgrade.

This ruler only measures in CM, which is not bad. But for other users in US who don’t actively use CM, this can be highly impractical and you must pay to be able to measure in inches.

To devs: I recommend a better way to implement your “pro” version, one that does not disrupt the entire function of this app. Why even offer a free version?

Very disappointing design. The fact that this app has so many positive reviews, brings it to the top of the search screen in the App Store. This is quite literally the fine line between an “app” and a SCAM.

Apple must remove this app or bump it down on the search results and allow other, more consumer-friendly applications with more functionality, appear closer to the top.

Apple, IOS users often look at the star-rating when searching for an app. It’s one of the top points in deciding to download an app. Allowing this at the top of your search results is very anti-consumer.
