What each check needs from your phone, and which phones fit best. Payments are non-refundable, so look here first.
| Check | Needs | Why |
|---|---|---|
| Room map | Rear LiDAR | LiDAR measures distance, which lets the app map the room and show where to look. iPhone Pro and Pro Max (12 Pro and later) and iPad Pro 2020 and later have it. Room mapping needs iOS 16 or later. |
| Lens glint | Flashlight on while the camera runs | A camera lens throws a small, steady reflection back at a light. The phone has to keep its flashlight on while the camera is running to catch it. Phones that cannot do this are not supported. |
| Steady exposure | Manual exposure control | Locking exposure keeps the picture from re-adjusting mid-sweep, so a real reflection stands out from a changing background. |
| Infrared lights | Front camera that is sensitive to infrared | Some hidden cameras use infrared lights your eyes cannot see. Some front cameras can show them. You can test yours with a TV remote on the check page. |
| Wi-Fi networks | Android | Android lets the app list nearby Wi-Fi networks and compare them with known camera signatures. iOS does not allow Wi-Fi scanning. |
| Bluetooth devices | Bluetooth | The app compares nearby Bluetooth devices with known camera and tracker signatures. Android shows more detail than iOS, which limits what apps can read. |
| Ultrasonic beacons | Microphone sampling at 48 kHz or more | Ad-tracking beacons sit around 18 to 22 kHz. A microphone has to sample fast enough to hear that range. |
| USB-C accessories | USB-C accessory support | Accessories plug into the USB-C port. Support depends on the phone and is being confirmed. |
These tiers are being confirmed in our staged-room testing; we’ll publish results per device tier.
iPhone Pro / Pro Max, 12 Pro and later, and iPad Pro 2020 and later (rear LiDAR). Non-Pro iPhones, including 16 and 17, have no LiDAR. Latest iOS recommended (Room mapping needs iOS 16 or later).
A current Android flagship with USB-C accessory support. Android allows Wi-Fi scanning and fuller Bluetooth data; iOS blocks most of that.
Two devices: an iPhone Pro for optics and an Android phone for radio.
iPad Pro works well. Android tablets suit radio checks but have weaker cameras.
Phones that cannot keep the flashlight on while the camera runs.
Honest limits. A phone cannot detect:
That is why every sweep ends with places to check by hand. Our sweep guide shows how.
A red filter and a red LED ring that make lens reflections easier to see.
Adds wider radio checks through the USB-C port.
Lets the app work with a USB-C thermal camera.
A sweep reports only what it found during that sweep, using your device’s sensors. It is not a certification, inspection or guarantee. Nothing from your sweep is saved, shared or sold. No photos, video or results leave your device to be stored — results are shown to you and then discarded.
