Use the rear camera and flashlight to examine smoke detectors, clocks, outlets, televisions, mirrors, and other objects from different angles. LensSentinel gives you a clear camera-first workspace for manual reflection checks.
Darken the room and scan slowly with the rear camera. LensSentinel highlights persistent bright regions that may deserve another look, while reminding you that reflections and ordinary lights can produce similar effects.
Scan the Wi-Fi network for Bonjour services visible to your iPhone. Review service names and types that may help you understand what is present on the network.
Discover Bluetooth Low Energy broadcasts visible to iOS. Compare signal strength, reception count, advertised names, and limited broadcast details, then use signal tracking as a clue while moving around the room.
Use the iPhone magnetometer to compare magnetic-field changes near outlets, fixtures, clocks, and other objects. LensSentinel establishes a local baseline automatically, so you can begin checking without a separate calibration step.
LensSentinel does not force you through a long checklist. Open the app, choose the tool that fits the situation, and inspect in any order.
