I like the simplicity without unnecessary bells/whistles, just what i was looking for. Nice to simultaneously show inches and centimeters. However, this app only shows in landscape mode and can't flip to portrait mode. Moreover, it also locks up the phone in landscape mode and I can't get back to portrait mode unless I close this app first, which is a pain. I found a similar simple ruler app that can automatically flip between portrait and landscape, so I'll go with that one instead.

Close, but no cigar. I don't mind its simplicity, but I wanted accuracy. It's OK for crude measurement, but when I tried to calibrate, by aligning the 0 and 4" mark with a ruler, the 1, 2 and 3 inch markings were slightly, but noticeably, misaligned. The "calibrate" function seemed intuitive (finger-drag the ruler), but if my intuition was wrong, I could not find any guidance on the app. My generous 3-stars is only for those who don't care about precision. And, oh, the display is pretty.
