Know when your arrow is too light for your bow. Speed now shows grains per pound, and warns you when you drop below 5, the minimum most bow makers require to keep your warranty. See your arrow's momentum right next to its kinetic energy, the number many hunters use to judge penetration. Results now follow your region's units, or pick your own in Settings: speed in m/s, energy in joules, momentum in kg·m/s and total weight in grams alongside grains. Inputs stay in grains, inches and pounds, just like your spec sheets. Entering a setup is quicker. Jump between fields with the arrows at the top of the screen, tap any label to edit it, and swipe down to put the keypad away. Plus some smaller fixes and improvements.
