This ruler app is so cool for a crafter like myself. I crochet a lot of baby items ,and have to measure the circumference of hats and the length of baby shoes, etc.. It comes in so handy, I don't have to get up and hunt for a ruler in the house somewhere, cause it's right here on my phone!!!Thanks for putting it there!!!😀😀😀

Such a shame, have had this app for ages and suddenly they've mining my information for 100's of unrelated organisations/companies under the guise of legitimate interest. I started to turn them off, then gave up when I scrolled down to see a link to 100's more - each needing to be toggled separately. So I've just taken a screen shot, and uninstalling it!

Effective, no-nonsense app that does what it's supposed to. Has limited ads with short duration. Should have had a feature that restricts screen occupancy without affecting scaling.
