Precision Rifle HUD is first a Timer to help you keep track of the time left on the clock, but is also so much more. HUD takes the timer idea to the next level through its use of audio cues, allowing you to track time remaining without having to look at the watch. What sets this apart from other timers is the additional feature that are packed into the app. Use the built in bubble level to make sure you don't introduce any cant into your shot. Or use the inclinometer to get accurate dope for your next shot. Don't forget about the compass that can be used in conjunction with the DataCards to build custom profiles and PointsOfInterest for each stage with a VidoeGame like "WayPoint" so you don't have to hunt for targets ever again!
