Ratings and reviews

Very easy app for small measurements. I like it! When it opens, you can see the size of your phone screen, if that interests anyone. You should try it!

It's always out a little. They should really have you calibrate it with a larger increment so the accuracy is better. The larger the increment the less significant things like small perspective errors and rule widths are. That said, it can be useful if you don't need it to be perfect and just need a rough estimate.

Simple, easy app to measure something small when you don't feel like taking your ruler/measuring tape out.
