I use in competition
Unlike BreakInThings, I use this app in long-range tactical precision shooting competitions out to 1,600 meters. Superb aid although nothing can match my log book reflecting thousands of rounds under varying environmental conditions. But BreakInThings is correct, an elevation offset would be helpful and keep me from manually doing the trig on those across-the-valley shots when the target is at a substantially different elevation.
