Sonar LiDAR vs GuideDog Nav

IMPORTANT: This app works EXCLUSIVELY on iPhone Pro (12, 13, 14, 15, 16, 17) with a LiDAR sensor. Standard models without LiDAR are not supported. Sonar Lidar — feel your surroundings. Sonar Lidar turns the LiDAR sensor on your iPhone Pro (or iPad Pro) into a real-time sonar. As you point your phone ahead, it translates distance into sound and vibration, giving you instant feedback about what's around you. What it detects • Walls and obstacles in front of you • Low furniture — sofas, benches, tables • Steps and drop-offs ("cliffs") • Narrow passages and doorways How it works • Audio sonar: beeps get faster as you get closer, panning left/right toward the obstacle • Haptic feedback: feel the proximity through vibration • Posture guide: a gentle tone helps you hold the phone at the right angle • Night vision: an optional on-screen depth view • The screen stays awake while scanning Made to fit you Simple, essential controls up front — distances, sonar spread, low-obstacle and drop sensitivity — with an "Advanced Settings" section for fine-tuning. Full VoiceOver support. Important: Sonar Lidar is an experimental support tool. It does NOT replace the white cane, a guide dog, medical aids, or your own attention. Use it only in known environments and always stay alert. Requires a device with a LiDAR sensor. We strongly recommend testing the app in a safe, known environment to find the best tilt angle and sensitivity setting (adjustable in Settings) for your height and walking style.

GuideDog Vision is a navigation assistant designed for blind and visually impaired individuals. Built as a student project, it uses your iPhone's LiDAR sensor, camera, and AI to detect obstacles, walls, stairs, and hazards in real time. How it works: - Automatic protection: constantly scans and warns about obstacles - LiDAR distance sensing: real-time measurements in feet - AI object detection: identifies people, chairs, vehicles, and more - Cloud AI: detects stairs, wet floors, doors, and hazards on scan - Voice alerts with haptic feedback Controls: - Hold screen: speak a voice command - Double tap: scan surroundings - Swipe left/right: check sides - Voice: "What's around", "Is it safe", "Left", "Right", "Scan", "Help" Privacy: - All detection runs on-device - Cloud AI optional, only on scan - No images stored, no account needed Works best on LiDAR-equipped iPhones (12 Pro and later). Camera and microphone access required. Built as a student project to make navigation safer for the visually impaired community.
