Description
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 is an advanced mobility assistant designed for the blind, visually impaired, or anyone needing to navigate in dark or unfamiliar environments.
Harnessing the power of the LiDAR sensor in your device, the app scans the environment in real-time, translating the distance of obstacles into intuitive haptic (vibration) and audio signals.
KEY FEATURES:
• 3-Zone Navigation: Intuitive "Traffic Light" logic (Green/Free, Yellow/Caution, Red/Stop) for confident movement.
• Haptic & Audio Feedback: Feel the distance through variable vibrations and Geiger-style sounds.
• Smart Detection: Automatically identifies narrow passages (doorways) and low obstacles (tables/chairs), providing specific alerts.
• Nature & Trekking Mode: Optimized algorithm for outdoors with extended range and intermittent "Safety Flash" to stay visible to others.
• Fully Customizable: Adjust sensitivity, safety distances, and viewing angles (vertical/horizontal) to suit your needs.
• Accessibility First: High-contrast interface and full VoiceOver support.
REQUIREMENTS: Requires an iPhone or iPad with a LiDAR sensor (iPhone 12 Pro, 13 Pro, 14 Pro, 15 Pro or later; iPad Pro 2020 or later).
DISCLAIMER: This application is an experimental support tool and DOES NOT replace medical aids, the white cane, guide dogs, or user attention in any way. The developer disclaims all liability for the use of this application.
Sonar LiDAR is free and ad-free. If you find it useful, you can support development via the "Tip Jar" in settings.
IMPORTANT: CALIBRATION AND POSTURE This app is a support tool that requires personal learning and calibration. The accuracy of detection, especially for the "Cliff/Drop Detection" feature, heavily depends on how you hold the device.
Correct Posture: For optimal results, hold your iPhone in a natural position, slightly tilted forward (as if reading a message while walking). This allows the LiDAR sensor to "see" the floor ahead of your feet.
Incorrect Posture: Holding the device perfectly vertical (perpendicular to the ground) may cause the sensor to point too far down, triggering false "Cliff" alarms.
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.
