FindMyDevice is a powerful Bluetooth scanner that helps you find and track nearby wireless devices. Whether you lost your AirPods, need to locate a Bluetooth speaker, or want to see what devices are around you — FindMyDevice has you covered. SCAN & DISCOVER Detect all Bluetooth Low Energy devices nearby with one tap. See device names, manufacturers, signal strength, and estimated distance — all in real time. Supports 65+ manufacturers including Apple, Samsung, Sony, Bose, JBL, Beats, and more. SMART DEVICE RECOGNITION Automatically identifies device types — phones, tablets, watches, headphones, speakers, TVs, fitness trackers, smart home devices, and more. Each device gets a recognizable category icon so you know exactly what's around you. PROXIMITY RADAR Visual radar shows how close you are to a device. The closer you get, the stronger the signal. Use the built-in sound beacon that beeps faster as you approach your lost device. SIGNAL STRENGTH GRAPH (PRO) Monitor real-time RSSI signal changes with a live chart. Perfect for pinpointing the exact location of a hidden device by watching the signal get stronger as you move. DEVICE MAP (PRO) See all your discovered devices on a map. Every scanned device is automatically pinned to the location where it was found, helping you remember where you last saw it. SCAN HISTORY (PRO) Keep a complete log of all your scans. Review which devices were found, when, and where — organized by session for easy browsing. BACKGROUND MONITORING (PRO) Get notified instantly when your favorite devices appear or disappear nearby. Never miss when your AirPods come back in range or when a tracked device leaves your area. HOME SCREEN WIDGET See your nearby device count at a glance without opening the app. The widget shows your latest scan results right on your home screen. FAVORITES & CUSTOM NAMES Mark important devices as favorites for quick access. Rename any device with a custom name that persists across all scans. FREE FEATURES - 3 device scans per day - Full device list with categories - Device detail with proximity radar - Signal strength bar - Sound beacon for finding devices - Favorites and device renaming PRO FEATURES - Unlimited daily scans - Real-time RSSI signal graph - Device map with locations - Complete scan history - Background monitoring & notifications - Home screen widget Download FindMyDevice today and never lose a Bluetooth device again.

cool-radar turns the radios already inside your iPhone into a radar for the devices around you — with no extra hardware, and without inventing a single number. WHAT YOU SEE Nearby Bluetooth LE devices appear as contacts with an estimated distance, a bearing once there is enough geometry to support one, and a ranked guess at what each device actually is. The Wi-Fi card shows the link your phone is really on: type, interface, local address and subnet, the default gateway and the gateway's manufacturer. Where both ends have UWB hardware, distance stops being an estimate and becomes a measurement. HONEST BY DESIGN Every value carries a badge. "Measured" is a hardware reading. "Inferred" is a value the math derived. Distances read "≈ 4.5 m" because radio ranging is an estimate, not a ruler. When there is not enough geometry for a direction, the app draws a ring of possible positions and a question mark instead of a convincing-looking arrow. And when iOS simply does not expose something — neighbouring Wi-Fi networks, raw spectrum, Wi-Fi CSI — the app says so instead of filling the gap with fiction. THE MATH INSIDE • Log-distance path-loss inversion, with a per-device exponent that recalibrates itself from the geometry you walk • Kalman filtering with motion-gated noise, so a device that is standing still stops drifting on screen • Robust multilateration with Huber weights, so a single reflection off a wall cannot drag a position across the room • A naive-Bayes hypothesis engine that ranks device types from the broadcast name, company ID, advertised GATT services, transmit power, address policy and advertising cadence — and shows you the evidence behind every guess • Behaviour analytics over the signal time series: advertising interval, jitter, trend and periodicity • Radio tomography that maps excess path loss into an attenuation picture of the space FEATURES • Top-down radar with range rings, pinch to zoom, double tap to reset • Device list with search and type filters • Device card with signal history, ranked hypotheses and the evidence for each • Unwanted-tracker heuristics based on public advertising patterns • CSV export of a session • Full Russian and English, switchable inside the app PRIVACY All sensing and all math run on your iPhone. No account, no analytics, no tracking, no advertising identifier. One optional setting — off until you turn it on — may send a 24-bit manufacturer prefix to a public vendor database to name your router. Nothing else ever leaves the device. Use cool-radar only on networks and devices you are entitled to inspect. It does not decrypt Find My identities, does not enumerate neighbouring Wi-Fi networks, and provides no covert tracking of people. REQUIREMENTS iOS 18 or later. Bluetooth works on every iPhone. UWB distance needs U1/U2 hardware on both devices. Room geometry needs a LiDAR model. Anything unavailable on your hardware is shown as unavailable rather than simulated.

Verdict

The call

The clearest difference is in-app purchases: cool at none against DeviceRadar's 3. DeviceRadar's advantage is iOS requirement (14.0 vs 18.0). On price, ads and device support there is nothing between them.
