## Description

New: sharper basket detection — tilted baskets, baskets in shade, and more basket models. Point your camera at the basket and see the distance instantly, 100% on-device.

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.
• 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
