FreeRange Dryfire turns your iPhone into a dry-fire training range. Save money...ammunition is expensive, train at home before you go to the range. Chamber an in-cartridge laser trainer, point your phone's camera at a paper target, and FreeRange DryFire detects every laser pulse, maps it to the exact spot on the target, scores it against the target's zones, and records it as a shot. No live ammunition — just focused, repeatable practice at home...on any target. Train with purpose Go beyond blasting away at paper. Run structured drills built around real skills: • Par-time, draw, and reload drills on a shot timer • Transitions and zone-calling drills that make you read a cue and engage the right target • The USPSA classification ladder — draw, transition, and reload standards that report an honest class • Recall, a memory-ladder game that grows a target sequence every rep Any Target • Train on the same targets you shoot at the range. There's no need for specialized proprietary targets • Built in target creation tool lets you define hit boxes on commercial targets that you already own or purchase at your favorite sporting goods store. • Ships with hit box definitions for several well known target manufacturers to work out of the box. A built-in barcode scanner can also remember and load the settings for targets that have them. • Print reduced-scale USPSA and IPSC silhouettes at home, each with a built-in calibration bar and a setup code you scan to configure your session in one tap. See where every shot went • Live scoring and group analysis, shot by shot • Precision and dispersion stats done right — accuracy and precision reported separately, outliers surfaced instead of hidden • Split times, cadence, transition times, and hit factor • A plain-language takeaway after every session Profiles and Armory • Create multiple profiles to track stats individually • Weapons armory builds detailed information about your firearms to make the app more detailed and accurate Zero your optic A distance-aware zeroing tool captures your laser/bore offset and corrects for sight-height-over-bore, so your scoring stays honest at any training distance. Includes a boresight zeroing aid. Track your progress • Streaks, goals, milestones, personal records, and progression trends that only claim improvement when the data actually supports it. A daily challenge keeps you coming back. • Create shooter profiles and track progress individually across your devices. • Shooter stats and profiles automatically sync across devices (iPad & iPhone) that's logged into the same iTunes account. Private by design Everything runs on your device. No account, no sign-in, no server, no tracking.
