ChainRanger turns your phone into a disc golf rangefinder. Point your camera at the basket and the on-device AI finds the chains and shows the distance instantly — in meters or feet, plus whether the basket sits uphill or downhill. No laser, no GPS waiting, no pacing it off. HOW IT WORKS • Aim your camera at the disc golf basket. • ChainRanger detects the basket in real time and calculates the distance. • A stabilized reading shows on screen. All image processing happens 100% on your phone. Camera frames are never uploaded anywhere. KNOW YOUR CIRCLES Distance to the basket is not just a number — it decides which rules and stats apply: • Circle 1 (C1) is everything within 10 meters (33 ft) of the basket. Inside Circle 1 the putting stance rule applies: after releasing the putt you may not step past your marker, you must show full balance behind it. ChainRanger tells you instantly whether you are inside the 10 m circle, so a borderline lie never catches you out. • Circle 2 (C2) reaches from 10 to 20 meters (33–66 ft). Putts made from here separate good rounds from great ones. • Parked, C1X and C2 are the stat categories that actually measure putting: Parked is inside 3.3 m (11 ft), C1X counts Circle 1 putts excluding parked tap-ins, and C2 covers the long range. When you know the exact distance, every putt goes into the right category. READ THE ELEVATION — AND WHAT IT PLAYS LIKE Distance alone doesn't tell the whole story: an uphill basket plays longer, a downhill one shorter — and because a disc glides, every meter of height changes the throw far more than in ball golf. ChainRanger reads your phone's tilt to show the up/downhill angle and the height difference, and Full Range adds the plays-like distance from a disc-flight model, so you can pick your disc and power with confidence. LIDAR ASSIST ON IPHONE PRO On LiDAR-equipped iPhones, ChainRanger fuses the scanner with the camera measurement for sharper readings at close range. LiDAR also unlocks tape-free calibration — dial in your camera and basket dimensions without a measuring tape. On other iPhones the app measures with the camera only. PERFECT FOR PUTTING PRACTICE Set up at exact distances for structured putting routines. Train at 5, 7 and 10 meters instead of guessing — and watch your C1X percentage climb. FREE AND FULL RANGE • Free: exact distance everywhere inside Circle 1 (10 m) — a complete putting trainer. Try Full Range with 10 free full-range readings. • Full Range (one-time purchase, no subscription): exact distance at all ranges, including Circle 2 and beyond, plus the plays-like distance on sloped holes. FEATURES • Real-time disc golf rangefinder using your camera • Distance to the basket in meters or feet • LiDAR assist on iPhone Pro models for close-range precision • Uphill/downhill angle and height difference to the basket • Plays-like distance on elevation, from a disc-flight model (Full Range) • Basket presets for PDGA-verified target models, or dial in custom dimensions • Calibrate at any known distance — the hole length from the tee sign will do • Three detection modes: Simple is the lightest, Pro sees the farthest, Balanced fits most iPhones best • Stabilized reading with a soft haptic tick when it settles • Hold button to freeze the reading • Magnifier zoom to reach far-away baskets • Supports multiple rear camera lenses with per-lens calibration • Smart exposure that locks onto the detected basket, tap to adjust • Power-saving mode and automatic heat protection for long sessions • Built-in guide with tips for getting the best readings • 100% on-device AI — works without a network connection GOOD TO KNOW • ChainRanger measures the distance from you to the basket. To measure the length of your throws, use a GPS measuring app or a laser rangefinder. • ChainRanger is a measuring aid for practice, casual rounds and competition. Grow your range. Find the chains.
