Sonar LiDAR

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.
