RangeZero is a modern firearm zeroing and range log app built to help shooters organize firearm profiles, calculate sight corrections, save range sessions, and keep better records over time. Whether you are confirming a zero, adjusting sights from a measured group, marking impacts on a target photo, or saving session notes for later, RangeZero gives you a cleaner way to track what happened at the range. Key Features: • Firearm Profiles Save rifles, handguns, shotguns, calibers, sight systems, click values, preferred zero distances, ammo notes, and ballistic setup details. • Choose a Zero Method Use Manual Guided Zero, Adjust My Sights, Photo Zero, AR 10-yard target workflow, or USMC 25m / 300m target workflow. • Sight Adjustment Calculator Enter target distance, group offset, and click value to calculate elevation and windage corrections. • Photo Zero Mark scale points, point of aim, and shot impacts on a target photo. RangeZero calculates group size, offset, and suggested sight correction. • Printable Zero Targets Generate printable AR 10-yard and USMC 25m zero targets with clear instructions and scale checks. • Range Sessions Save zero attempts, group size, ammo used, location, notes, target photos, and confirmed zero status. • PDF Reports Export range reports with firearm details, session notes, adjustment data, and attached target photos. • Find Nearby Ranges Search nearby shooting ranges, clubs, training centers, and directions using Apple Maps. • iCloud Backup Back up firearm profiles, sessions, app preferences, and settings to your private iCloud account. RangeZero is designed for lawful range, sporting, and training use. Calculations are estimates and should always be confirmed at the range. Always follow firearm safety rules, local laws, and range procedures.
