【實用工具app】MeterStick|最夯免費app-gigacircle

Turns your phone into an accurate ruler, with both inches and centimeters! Allows for scrolling down up to the 100 cm mark, making it a "meter stick." Distances calculated accurately in all but emulated (on-computer) environments. Users of custom ROMs and a select few phones may produce erroneous results -- please manually enter your phone's DPI in the "Preferences" menu to fix this issue.
