An ok App. Says it'll convert mm/cm/in but there's no function to do so. it doesn't work as a measuring tape. Others are right when they say as long as you know the length of your phone it's about as helpful as that. Ads pop-up 2 often/quickly. I do like the toggle buttons for measuring items small enough to fit on screen. Graphics are nice/simple. Those that claim it works as advertised ought to kindly share how. Overall, it's okay for what it is.

Easy to use on my Samsung; just click the buttons on screen to get what you need. Nothing is labeled except to change to cm from inch and vice versa so the other options take getting used to since they are "pics". Few short ads (15-30 seconds) that allows even more options like edge screen start, dark mode, always on. This is using the free version which is all I need!

I can easily see when something I'm drawing is off. It drives me bonkers! Finding an accurate measuring device while out of the house, is a hassle! This just made that soooo much easier! Hit the circle with the cross in the center or the 3 menu dots to calibrate your ruler! Use a ruler, or what you have to line up where the Mark's should be, then touch your screen and move the end left or right to adjust it! It's as simple as that! Provided you have an accurate graduated scale to use!
