Good as far as it goes (no pun intended). Given it's simplicity, it's not clear to me why it costs 99 cents (i'd give it another star if it were freeI have three suggestions for improvement: allow the two columns to give different measurements (I.e. so that one could run metric and the other imperial simultaneously); allow various increments in the imperial measurements (e.g., 1/8s or 1/10s); and allow the two columns to "slide" independent of each other (I.e., one could start at 0" and the other could be set to measure up from, say, 1 3/8")
