Description:Grains: Archery Calculator is a precision archery tool for bowhunters and target archers. Quickly calculate total arrow weight in grains, front of center FOC, kinetic energy and momentum, then generate trajectory and sight marks to speed up tuning and practice. Build and manage multiple bow and arrow profiles, compare setups, and choose units in grains or grams, yards or meters. Designed for fast, accurate decisions at the range or in the field, this archery calculator helps you balance speed, penetration, and accuracy before you cut arrows. Keywords include archery calculator, arrow FOC calculator, bow sight tape calculator, arrow speed, trajectory chart, and bow tuning app.
How to use:1. Download and open the app, choose units, then create a bow profile with basic specs. 2. Enter arrow components and their weights to auto calculate total grains, FOC, energy, and momentum. 3. Add measured or estimated arrow speed and select distance steps to generate trajectory and sight marks. 4. Save the setup, duplicate it to test different point or insert weights, and compare results to find your ideal build. 5. Go to the range to verify impacts, fine tune the input speed until marks align, and record your final sight marks for hunting or competition.
