Life saver!

I live this app! As a product designer, I always think of new ideas wherever I might be. However even though I can think of an idea wherever I'm, I don't alway have a ruler. Therefore I use this app a lot.

Keep you finger steady?

You need to make sure you don't move the finger touching the screen to get accurate results. Easier said than done.


I got this because we we've had a ruler around the house to see how tall I was...but this might be a little off cause it's saying I'm 5'8 then 5'9 then a 5'6
And I'm clearly you'll just have to estimate it...but it's alright to get an overall basis I guess....
