ILENS helps you check a room for hidden cameras and unexpected devices, using the hardware already in your iPhone. Built for hotel rooms, short-term rentals, changing rooms, and any space you did not set up yourself. ILENS gives you a structured way to look. It cannot promise a room is clean, and it does not decide for you. WHAT ILENS CHECKS Devices on your Wi-Fi network Lists the devices sharing the network you are connected to, and the open services each one answers on, so an unfamiliar camera or recorder stands out from the router and the TV. Bluetooth Finds nearby Bluetooth devices that are broadcasting, including ones with no screen and no obvious owner. Camera lens check Uses your camera to help you spot the reflection a lens gives back. Move slowly across smoke detectors, vents, sockets, mirrors and clocks — the places cameras are usually hidden. ILENS points your eyes at the right places; you make the call. On-device object detection A model running on your iPhone can mark objects in view that look like cameras. It recognises shapes, not hidden cameras, so treat a mark as a place to look more closely. WHAT ILENS CANNOT DO We would rather say this up front than have you find out later. - ILENS cannot find every hidden camera, and no app can. A camera that is switched off, or one that records to a memory card with no wireless connection, leaves nothing for a phone to see. - Network and Bluetooth scanning only shows devices that are broadcasting. A camera on a separate network will not appear in the list. - Lens reflection depends on angle and lighting. It is a way of looking, not a verdict. - ILENS does not use infrared. The camera in your iPhone blocks infrared light, so no app on it can reveal heat or IR emitters. - An empty result means ILENS found nothing by these methods. It does not mean the room is clear. PRIVACY - No account, no sign-up. - Scans run on your device. - ILENS does not store photos, video or audio from your scans. - The free version is supported by ads. GOOD FOR - Travellers and hotel guests - People staying in short-term rentals - Changing rooms and fitting rooms - Anyone who wants a second look at a room they did not set up ILENS PREMIUM Upgrade to remove all ads and scan without limits.

SONAR: HIDDEN CAMERA AND TRACKER DETECTOR Sonar helps you check for hidden cameras, hidden microphones, and Bluetooth/Wi-Fi trackers, a privacy inspection support tool with infrared, Wi-Fi network, and Bluetooth scanning. Whether you're in a motel room, hotel, Airbnb, locker room, public restroom, fitting room, car, or your own luggage, Sonar helps you inspect the space in minutes. IMPORTANT: no phone app can guarantee with certainty that a space is free of hidden cameras. Sonar is a support tool, each finding comes with a confidence level so you can physically check the spot it flags. Always use it alongside a manual inspection. DETECTOR FEATURES Infrared scanner Point your phone's camera and look for the telltale reflection of hidden spy camera lenses, a common sign in cameras disguised as a button camera, pen camera, charger, smoke detector, or clock. Works best in a dark room and doesn't replace a physical check. Wi-Fi network and Bluetooth device detection Sonar scans the local Wi-Fi network and nearby Bluetooth devices to flag devices with characteristics of connected cameras or trackers. Each result shows a confidence level, not a definitive confirmation. Bluetooth tracker detector Flags signals from Bluetooth trackers nearby: in your car, bag, luggage, or personal belongings, as support against unwanted tracking during travel and everyday life. Guided sweep A practical checklist walks you through spots where cameras and microphones are commonly hidden: outlets, smoke detectors, picture frames, mirrors, chargers, clocks, and more, so you can physically inspect each one. Clear, straightforward results See the confidence level of each finding, with real-time visual indication, no technical jargon.

Verdict
The clearest difference is in-app purchases: ILENS at none against Sonar's 3. Sonar's advantage is ads (none vs shown) and update cadence (every 3 weeks vs every 2 months). On price, device support and iOS requirement there is nothing between them.
