ChainRanger vs ThrowPrint

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.

ThrowPrint is the disc golf stats app that tells you which disc is actually costing you strokes. Most scorecards just track your number. ThrowPrint tracks the why. Tag every throw by the disc you threw and the shot shape - hyzer, flat, or anhyzer - and ThrowPrint turns it into feedback that actually lowers your score. WHAT YOU GET - Per-disc charts - your good vs OB/miss rate for every disc in your bag, and the disc-and-shape combos leaking strokes (like "your driver on anhyzer goes OB most of the time"). - Per-hole heat-maps - a color-coded map of every hole on the courses you play most, so you see exactly where you lose strokes. - Satellite course maps - search 1,800+ courses and see the hole layout, par, distance, and live wind on a real satellite map as you play. - Mark your shots - drop each throw on the map automatically from your location, or tap to place it, and see your whole round replayed shot by shot. - Real distances by disc - ThrowPrint measures how far every disc actually flies for you, average and longest, so you finally know your gaps. No other app ties distance to the exact disc. - One-tap logging - your disc and shot shape stay selected, so most throws are a single tap. Fast enough to keep up with your card. - Smart tee defaults - your driver is pre-selected off the tee, then it follows your last disc on approaches and putts. - Multiple bags - a main bag, a glow bag, a tournament bag. - Live round scoring - your score vs par updates as you play, with a recap at the finish. - Works offline - log a full round, and reload a course map you have already played, with no signal. Your data stays on your phone. - No sensors, no hardware - just your phone and your bag. WHO IT'S FOR Whether you're grinding to break par or just want to know which disc to trust on the dogleg right, ThrowPrint shows you what to throw - and what's holding you back.
