Lots of adds but still usable. Works pretty good for what I need it for. 1 star off for having to read it sideways and 1 star off for the adds. I don't mind the adds, I mean c'mon, it's free, but there is a LOT of ads. Maybe try having an ad on startup but not every 3 minutes when your using it.

It's a ruler! If you need to measure a large area then wait til you can get your hands on a tape measure. Otherwise if you need to quickly check the size of something when you're out on the go it's a handy tool to have. I have an iPhone SE, iPhone 4 & an iPad & have used it on all of them & have had no problem with inaccuracies. Yes, there are ads but they have not interfered with my use of the app. Good app. Does what it says.

Works well, does exactly what it says it will do. Yes, there is an ad occasionally, but it doesn't interfere with this app's simple function.

Instead of assume normal people know what the diagonal dimension is of their phone and ask them to enter it as the first thing they do, why don’t you detect the phone model and do it automatically?It seems like meeting someone for the first time and you go straight to “how old are you?”
