Scanr - Bluetooth Finder

New v2 engine scans faster and digs deeper. Spot hidden BLE devices, track signal strength live, and follow the proximity radar straight to your lost gear.

Scanr is a fast, focused Bluetooth and BLE scanner for iPhone, iPad, Mac, and Apple Vision. Discover every nearby Bluetooth Low Energy peripheral, watch its signal strength in real time, and follow the proximity radar to whatever you're looking for.

Whether you're a developer debugging firmware, a tinkerer mapping smart-home gadgets, or just trying to find a misplaced pair of earbuds, Scanr gives you a clean, no-nonsense view of the wireless world around you.

WHAT YOU CAN DO

• Scan continuously for BLE peripherals, beacons, and accessories
• See live device names, identifiers, manufacturer data, and RSSI
• Watch signal strength change on a live graph as you move
• Use NearBy mode as a proximity radar to walk straight to a device
• Surface hidden or unnamed BLE broadcasters in your surroundings
• Export full scan sessions as JSON or CSV for later analysis
• Filter and sort the device list to cut through the noise

GREAT FOR FINDING

• AirPods, Beats, Bose, JBL, Sony, and other wireless headphones
• AirTags and other small BLE trackers
• Apple Watch, Fitbit, Garmin, and fitness wearables
• Smart bulbs, plugs, locks, thermostats, and IoT sensors
• Speakers, game controllers, styluses, and BLE keyboards
• Stray dev boards, ESP32s, nRF modules, and prototype hardware

BUILT FOR DEVELOPERS

• Inspect advertising payloads and service UUIDs at a glance
• Track RSSI over time to estimate distance and link quality
• Export structured data to feed your own tooling or notebooks
• Lightweight engine, tiny footprint, instant cold-start scans

NEARBY PROXIMITY MODE

Pick any device from the list and tap into NearBy. Scanr turns into a real-time signal radar, showing how close you are as you move. Walk warmer, walk colder, and zero in on the missing peripheral hiding under a couch cushion or buried in a bag.

PRIVACY FIRST

Scanr runs Bluetooth scans entirely on-device. Nothing leaves your iPhone, iPad, Mac, or Vision Pro. No accounts, no trackers, no analytics. The developer does not collect any data from this app.

UNIVERSAL ACROSS APPLE PLATFORMS

One purchase covers iPhone, iPad, Mac, and Apple Vision. The interface adapts to each device, with full keyboard navigation on Mac, multitasking-friendly layouts on iPad, and a spatial-aware view on Vision Pro.

WHY PEOPLE PICK SCANR

• Honest, ad-free utility built by an indie developer
• Tiny download, fast launch, no bloat
• Clean SwiftUI design that respects your data and your time
• Frequent updates with real changelog notes

Note: Scanr can only detect devices that broadcast standard Bluetooth Low Energy advertisements. It cannot show offline AirTags, audio-only Classic Bluetooth links that are already paired and idle, or devices that have been intentionally silenced. Distance from RSSI is an estimate, not a precise measurement.

Pop Scanr open, hit scan, and see what's whispering on the airwaves around you.
