ICIDO vs Ear Sonar

ICIDO turns your iPhone's LiDAR scanner into an indoor map you can navigate — no beacons, no Wi-Fi setup, no internet. Scan a room once and ICIDO remembers its exact shape. Walk back in later and it recognizes where you are and guides you to any spot, even where GPS has no signal. HOW IT WORKS • Scan — sweep your iPhone across a room to capture its walls, floor, and furniture in 3D. • Find yourself — tap Find Me and ICIDO works out which place you're in and exactly where you're standing. • Navigate — pick a saved spot or tap the map, and a route is drawn on the real floor, steering around furniture and through doorways. FEATURES • Tag any spot — drop a waypoint ("printer", "exit", "room 204") and route straight to it. • Rooms, detected automatically — larger maps split into named rooms at the doorways. • Grow your maps — add newly scanned areas to a place, or combine two overlapping maps into one. • Buildings — stack scanned floors into a building and ICIDO follows you between them. • History — revisit where you've been with trails and heat maps. • Share — send a place as a .spacemap file; the other person can open and navigate it. PRIVATE BY DESIGN Everything stays on your device. No account, no sign-in, no analytics, no networking. Your scans never leave your iPhone. REQUIRES LiDAR ICIDO needs the LiDAR sensor, available on iPhone 12 Pro and later Pro models (Pro and Pro Max). It will not scan on non-Pro iPhones.

Ear Sonar is an accessibility app that helps people who are blind or have low vision sense nearby space. It uses the iPhone’s rear LiDAR to scan what’s ahead, then turns that depth into spatial audio—or haptics—so you can “hear” the environment. What you can hear • Distance: nearer sounds arrive sooner, denser, or higher in pitch; farther sounds are sparser and lower • Direction: binaural spatial audio places objects to your left or right • Shape cues: flat walls, slopes, and gaps create distinct sonic rhythms Four sensing modes • Echolocation: row-by-row pings outline space like sonar returns • Pitch sonar: a rising scan line encodes distance as pitch in real time • Continuous sonar: a fixed center line for a live depth profile while you walk • Haptic sonar: vibration timing encodes distance—no headphones required Semantic markers Optionally detect people, vehicles, dogs, chairs, tables, doors, and more, then announce them in stereo from their real-world direction. All processing stays on device; nothing is uploaded. Tips • Stereo headphones are recommended (Apple headphones with head tracking and spatial audio work best); haptic mode can be used without headphones • Full VoiceOver support, including gestures and the rotor • Requires an iPhone with LiDAR (iPhone 12 Pro and later Pro models) • This is an assistive tool—not a replacement for a cane, guide dog, or your own judgment when traveling Open the app and start hearing space. Camera preview is on by default so sighted helpers can see what’s being scanned. To keep the experience focused, the app intentionally avoids UI that isn’t essential to core sensing.
