Finx is the most advanced device detection app for iPhone. Whether you're checking a hotel room, Airbnb, or office for hidden cameras, scanning your network for unknown devices, or tracking a lost Bluetooth gadget — Finx puts powerful privacy tools in your pocket. HIDDEN CAMERA DETECTOR Analyze your environment for infrared light sources and electromagnetic signals that hidden recording devices emit. Spy cameras and covert recorders are designed to be invisible — Finx is designed to find them. BLUETOOTH SCANNER Discover every Bluetooth Low Energy (BLE) device broadcasting nearby. See device names, signal strength, estimated distance, manufacturer identity, and service UUIDs. Unnamed devices with strong signals are automatically flagged — a hallmark of hidden trackers. WI-FI NETWORK SCANNER Map every device on your local network in seconds. Identify smart TVs, IP cameras, printers, routers, and IoT devices. View hostnames, IP addresses, and device categories at a glance. DEVICE TRACKER Lock onto any Bluetooth device and track its signal strength in real time. Use the live proximity indicator to physically locate lost earbuds, speakers, tags, or any BLE accessory.

Argus checks any room for hidden cameras and trackers with four scanners on your iPhone: Wi-Fi, Bluetooth with a tracker locator, a camera finder with Lens and Infrared modes, and a magnet check. The Lens camera finder is free with no scan limit and no account, and so is finding a tracker. Hotel rooms, Airbnbs and holiday rentals, changing rooms, gym lockers, rental cars. No app finds every camera, and no single method does: one in a smoke detector may sit on the room's Wi-Fi, or record to a memory card and touch no network. That is why Argus checks four ways. WI-FI SCANNER Finds the devices on the network you joined and flags those answering on camera ports: RTSP video streams, ONVIF, Hikvision, Dahua, XMEye, V380, Ezviz, Tapo, Reolink. Printers, routers and TVs that name themselves are set aside. Free: the device count, camera alerts and identified devices by name. Argus Pro shows which device it is: address, open ports and what its service says about itself, often the firmware. Blind spot: hotel guest Wi-Fi often keeps devices apart; Argus says so instead of calling the room clean. BLUETOOTH AND FIND IT Lists nearby Bluetooth devices and recognises item trackers: Tile, Samsung SmartTag, Chipolo, Pebblebee, Google Find My Device tags. Find it walks you to one: a ring fills as you get closer, ticks quicken, an optional beep helps. Free: the count, possible trackers and finding them. Argus Pro: every device by name and signal, and Find it for any of them. Blind spot: a paired, silent device doesn't advertise, and iPhone may hide Apple's Find My tags from apps (iOS warns about those itself). CAMERA FINDER: LENS AND INFRARED Lens mode, free: lights off, torch on, sweep slowly. A lens returns a tight bright glint; a red, green or blue filter makes it stand out. Infrared mode, Argus Pro: night-vision cameras light a room with infrared your eyes can't see, and an iPhone camera often can. Argus looks for that light and beeps when it spots one. Blind spot: both need a dark room, and a shiny point or ordinary light can trigger them. A flag means look closer. MAGNET CHECK, ARGUS PRO Hold the phone close to a smoke detector, clock or charger: the dial jumps at the metal and magnets of hidden electronics, with a buzz and a beep. Screws and pipes move it too, so compare with a similar object you trust. A FIVE-MINUTE SWEEP Scan the Wi-Fi. Run Bluetooth from the bed and follow any tracker with Find it. Lights off: sweep everything facing the bed in Lens, then Infrared. Pass the magnet over whatever stood out. Two checks pointing at one object: inspect it. PRIVACY No account, no ads. What a scan finds stays on your iPhone. Camera frames and sensor readings are never recorded; only Wi-Fi and Bluetooth scans are saved, on your phone. Subscriptions run through Apple and RevenueCat; crash reports and usage analytics are not linked to you. No tracking. In 13 languages: English, Spanish, Portuguese, French, Arabic, Turkish, Korean, Japanese, Traditional Chinese, Indonesian, Vietnamese, Hindi, German. FREE AND ARGUS PRO Free: the Lens camera finder; Wi-Fi and Bluetooth scans with their counts, camera and tracker alerts; identified Wi-Fi devices; finding a tracker. Argus Pro: which Wi-Fi device it is and its details; every Bluetooth device by name; Find it for any device; Infrared mode; the magnet check. Requires iOS 16 or later.
