Hidden Device Radar
Utilities
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Scans that turn up hundreds of devices are now much faster and easier on your battery — and every scan still ends with a plain answer about what it means.
Worried someone is watching or following you? Hidden Device Radar helps you find hidden cameras, trackers, and unknown smart devices — right from your iPhone.
Whether you're checking a hotel room, a short-term rental, an office, a car, or your own home, Hidden Device Radar gives you a fast, private way to spot devices that may be recording or tracking you.
WHAT IT DETECTS
• Bluetooth devices — trackers (AirTag, Tile, SmartTag, Chipolo), cameras, speakers, wearables, and other IoT gadgets
• Wi-Fi / local network devices — IP cameras, baby monitors, NVRs, doorbells, and smart-home hardware
• Unknown trackers that may be traveling with you
• NFC tags — tap to identify a chip hidden in an object (on supported iPhones)
KEY FEATURES
• Real-time threat scoring — every device is flagged as Info, Suspicious, Elevated, or Critical
• Signal Strength Finder — a "warmer / colder" proximity graph that helps you physically locate a device (Pro)
• Scan modes for a quick sweep, a single room, or a whole floor
• Detailed device fingerprints and manufacturer identification
• Detection history so you can tell what's new versus what's always there
• 100% on-device — your scans never leave your iPhone. No account, no tracking, no ads.

HONEST ABOUT LIMITATIONS
Hidden Device Radar detects devices that broadcast Bluetooth, Wi-Fi, or NFC signals. Bluetooth, Wi-Fi, and NFC advertisements are unauthenticated, so results are strong investigative leads — not legal proof of a device's identity or intent. The app cannot detect devices that are powered off, purely analog/wired, or that broadcast no signal.
PRIVACY FIRST
Everything runs locally on your device. We don't collect, upload, or sell your data. There are no accounts and no ads.
Use Hidden Device Radar to check your own spaces and protect your own privacy. Always follow the laws in your area.
more Much faster in busy places
A scan in a hotel, an airport or an apartment block can turn up hundreds of devices, and the app slowed to a crawl and drained the battery when it did. That is fixed: results stay smooth however many devices are found, and a long scan costs far less power.
A more honest verdict
The verdict at the end of a scan sometimes warned that local-network scanning had not run when it had, which made a real warning easy to ignore. It now reports only what actually happened during that scan.
Display fixes
Threat levels no longer wrap awkwardly next to long device names, and the app keeps its dark appearance instead of washing out on devices set to Light Mode.

Every scan now ends with an answer
A list of devices is not an answer. Scans now finish with a plain-language verdict: what was found, what it means, and the one thing worth doing next. If something deserves attention it says so and takes you to it. If the scan could not cover everything — Bluetooth ran but the network was not checked — it tells you that too, rather than showing an empty list that looks like good news. Tap "Why this verdict?" to see exactly what it was based on.
Name the things we cannot identify
Some devices broadcast nothing an app can read. Your own hardware is often among them. Now you can name anything yourself — "Apple TV Remote" — and that name sticks, replacing whatever we guessed. Name it, mark it as known, and it stops crowding your results for good. Names you add are marked as yours, so they are never confused with something the app identified.
Find cameras that broadcast nothing at all
A camera with no radio cannot be scanned for. Lens Glint Finder turns your torch into a guided visual sweep, walking you through the places cameras actually get hidden and using the reflection off the lens to give them away. A manual aid, deliberately — it does not claim to detect anything by itself.
Deep scan for cameras hiding on your network
Some cameras sit on the Wi-Fi and never announce themselves. Deep scan checks each address on your own network for the ports cameras and recorders listen on. It is off until you turn it on, only ever looks at the network you are already connected to, and sends nothing to the devices it finds.
More devices recognized by name
Cheap unbranded keyfinders are now identified as trackers rather than unknown oddities, which means they can raise follow-me alerts like any other tag. Tags that name themselves as Find My devices are caught even when they advertise nothing else. Trackers on Google's Find My Device network are recognized alongside Apple Find My, and Windows computers are identified as what they are instead of an unexplained signal.
Evidence you can hand to someone
Attach up to five photos to any finding. Exports carry a SHA-256 integrity digest so a recipient can verify the file has not been altered, alongside a For Law Enforcement section covering where the data came from and — just as importantly — what it cannot prove on its own.
Ratings you can read at a glance
Threat level and identification confidence were easy to confuse: a device the app was only fairly sure it had identified could look like a warning. They are now clearly separate, colour marks risk and nothing else, and a legend explains both.
Your data, your switches
Location tagging and follow-me notifications can be turned off, and back on, whenever you like — right in the app, without digging through Settings. They now work on Mac as well as iPhone.
A fresh look
New backgrounds and materials throughout, so the app reads more clearly in a dark room — which is usually where you are using it.
Also in this release
NFC Tap-to-Identify enhancements
Sort what you find by signal strength, so the nearest device is first when you are sweeping a room.
Not finding something? The app explains what each of your devices can see, and points out that a Bluetooth scan alone will never find a Wi-Fi camera.
Reporting a wrong result asks what was actually wrong, so corrections reach us in a form we can act on.

Find cameras that broadcast nothing at all

A manual aid, deliberately — it does not claim to detect anything by itself.
Deep scan for cameras hiding on your network
Some cameras sit on the Wi-Fi and simply never announce themselves, so nothing turns up in an ordinary scan. Deep scan checks each address on your own network for the ports cameras and recorders listen on. It is off until you turn it on, only ever looks at the network you are already connected to, and sends nothing to the devices it finds — it opens a connection and closes it again.
Unbranded IP cameras
Cheap cameras and recorders often advertise no recognizable vendor name. They are now identified by the services and ports they expose, so a no-name camera is no longer invisible.
More devices recognized by name
Cheap unbranded keyfinders — the kind sold everywhere for a few dollars — are now identified as trackers rather than unknown oddities, which means they can trigger follow-me alerts like any other tag.

Trackers on Google's Find My Device network are recognized alongside Apple Find My, and Windows computers are identified as what they are instead of appearing as an unexplained signal.

This update makes Hidden Device Radar smarter at spotting what actually matters.
SMART GLASSES & WEARABLE CAMERA DETECTION
• Detects nearby camera-equipped smart glasses, including Meta Ray-Ban, Snap Spectacles, Echo Frames, Xreal, Rokid, and Vuzix
• Flagged as wearable surveillance so you know a camera may be in the room
FOLLOW-ME TRACKER ALERTS
• Get notified when the same tracker is detected following you across multiple locations — the real sign of unwanted tracking
SIGHTINGS MAP
• See where a device has been detected on a private map
• Location tagging is optional and stays entirely on your device
WALLET & CARD TRACKER DETECTION
• Recognizes credit-card-shaped trackers including Tile Slim, Pebblebee Card, UGREEN FineTrack, KeySmart SmartCard, and Nomad Tracking Card
• Tells you exactly where to look — card slots, bag linings, and zip pockets
SMARTER, MORE ACCURATE DETECTION
• Cameras and recorders are now ranked by real-world risk instead of signal certainty
• New per-device timeline showing how long and how often a device has been around
FEWER FALSE ALARMS (thanks to your reports!)
• Health wearables like the Oura Ring are no longer mistaken for cameras
• Streaming devices such as Roku now show the correct manufacturer
• Theme-park and cruise wristbands and fitness bands are recognized as harmless
• Fixed devices incorrectly merging across Bluetooth and Wi-Fi
PRIVACY FIRST, ALWAYS
• Everything runs on your device — no account, no tracking, no ads
This build fixes issues found in review and reported by users:
• Smart glasses detection (Meta Ray-Ban, Spectacles, Echo Frames and similar)
• Wallet/card tracker detection (Tile Slim, Pebblebee Card, UGREEN FineTrack,
KeySmart SmartCard, Nomad Tracking Card)
• Follow-me alerts when the same tracker appears at multiple locations
• Private on-device map of where a device was detected
Please test: start a scan in a few different places, confirm devices are
ranked most-risky first, and report anything misidentified using the
"Report misidentification" button on a device card.
Note: NFC Tap-to-Identify requires an iPhone (not available on iPad/Mac).
Keep the misidentification reports coming — they directly shaped this release.
1.2 Aug 17
This update sharpens detection accuracy:
• More reliable threat ranking — cameras and recording devices are now rated by real-world risk, not just signal certainty
• Fewer false alarms — theme-park and cruise wristbands (like Disney MagicBand+) and fitness bands are now correctly recognized as harmless
• New per-device persistence timeline showing how long and how often a device has been seen
• Improved tracker confirmation and privacy protections
Thanks for using Hidden Device Radar — keep the feedback coming!
