Candle vs Sonar LiDAR

Discover seamless and barrier-free navigation with our app, specifically designed for blind and visually impaired users. With our innovative solution, you can effortlessly save Points of Interest (POIs) and navigate safely to your desired destinations. Our app is developed with complete Talkback support, ensuring full Voice-Over functionality, making it exceptionally user-friendly for people with visual impairments.

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.
