RangeZero vs Zero Considerations

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.

A ballistics calculator that reads the paper. Photograph your shot group and Zero Considerations gives you the exact clicks your turret takes to move point of impact onto point of aim. Everything that measures and calculates runs on your phone, with no signal. Your firearms, loads, photos and results never leave your device. The one part that uses the internet is the optional weather fill, which sends an approximate location to a weather service and stores nothing. Leave it off and the app never touches the network. SIGHT IN FROM A PHOTO • Shoot your group, photograph the target, and the app finds the target and the holes, measures the group against your point of aim, and gives the exact click adjustments for your turret. • 1,043 optic entries carry the makers' own click values, so the same scope in MOA and in MIL gets the right answer. • Scale comes from a printed target with coded corners that also squares up camera tilt, or from a store-bought target the app recognizes. Type a known span for anything else. A manual fallback always works. • Sighting in indoors? Proxy zero works out where to print at 25 yards so you should be on paper at 100. The app calls a proxy zero a prediction, because that is what it is. • If it is not sure it has your target, it shows you the photo and asks. It will not print a confident call it cannot stand behind. BALLISTICS THAT MATCH YOUR RIFLE • Drop, wind and energy in MOA, MIL or clicks. • Temperature, pressure, humidity and wind fill in from your phone, or type them yourself. • A wind dial you drag to your call, with optional compass capture. • Point-blank range and maximum ordinate. • Zero and true: from a photographed group at a known distance, back out your true muzzle velocity so your dope matches what the rifle actually does. KNOW YOUR OPTIC BEFORE YOU SHOOT • 345 reticle patterns drawn to the makers' published subtension sheets wherever the maker publishes the numbers, to scale, so you can see your real holdovers — and where one never did, the app says so on the reticle. • A suggested zero distance for each reticle, based on your load. • A mount and riser calculator that works out true height over bore from your rail and mount, offset optics included. Bore sight it, then confirm the zero on paper. SET UP YOUR RIGS ONCE • Save firearms, optics, mounts, loads and lasers as setups you reuse. • 852 firearms and 512 factory loads built in, or add your own. • Device loadouts: primary optic, offset, laser and irons on one rifle, each with its own zero. WHAT IT COSTS • One purchase. No subscription, no ads, no analytics, no account. For education and lawful sporting use. Always verify your zero and dope on paper before relying on them.
