Designed to provide peace of mind, not false alarms.

Sonar was born from a simple question: how can you help someone inspect a hotel room or an Airbnb without relying on an expensive service or guesswork? The answer was to transform the sensors that already exist in cell phones into an honest scanning tool.

• Let's be clear: Sonar never definitively says "camera found" or "safe environment"—each finding comes with a level of confidence and an explanation.
• We are private by default: no account, no server, no data collection. What happens on your device, stays on your device.
• We're practical: the app was designed to be used in seconds, whether checking into a hotel or before entering a fitting room.
