HIKER is the Swiss Army knife of RF scanning. One app covers Bluetooth, Wi-Fi, cellular, GNSS and drone signals, plus a full set of network and terminal tools. It shows you every wireless device around you and tells you which ones shouldn't be there.

SCAN EVERY RADIO
• Bluetooth LE and Classic: names, makers, beacons, signal strength and raw advertising data
• Wi-Fi: every access point with channel, width, standard, security, WPS details and router make and model
• Wi-Fi Direct: printers, TVs, cameras and other peers announcing themselves nearby
• Cellular: serving and neighbor cells with band, frequency, signal quality, timing advance and distance to the tower
• GNSS: every satellite in view across GPS, GLONASS, Galileo, BeiDou and more, with signal strength and your fix in detail
• Drones: Remote ID broadcasts with the drone's flight path and the pilot's location
• Manufacturer lookup from the full IEEE and Bluetooth SIG registries, built into the app

FIND HIDDEN TRACKERS
• Tracker Sweep walks you through checking a room, car or bag one step at a time
• Detects Apple AirTags and Find My tags, Google Find Hub tags, Samsung SmartTags, Tile, Chipolo, Pebblebee and more
• Passive Tracker Alerts warn you when a tracker stays near you for too long
• Follow the signal strength to find a tracker, or make an AirTag play a sound
• Followers: see any device that has turned up at more than one place you've been

WATCH AND ALERT
• Put any device on your watchlist and get a notification when it comes back into range
• Watch by exact address, or by what a device broadcasts so it still matches after its address changes
• Background scanning and Pocket Mode keep HIKER working with the screen off

MAP YOUR SURVEY
• Every outing on the map, showing where you saw each device
• Signal heatmaps, cell tower positions and drone flight tracks
• Surveillance camera and license plate reader overlay from OpenStreetMap
• Mark a spot with Found It and come back to it later
• Export to CSV, KML and NMEA

ANALYZE THE AIRWAVES
• Spectrum, channel waterfall and airtime across 2.4, 5 and 6 GHz
• Airspace breakdown by radio type, distance, security and vendor
• Cell site history, carriers, handovers and signal over time
• Wi-Fi ranging to measure the distance to access points that support 802.11mc
• Connect to a Bluetooth device and read its name, model and services

NETWORK TOOLS
• LAN Scan finds every device on your network and identifies it using mDNS, SSDP, UPnP and NetBIOS
• Ping, traceroute, DNS, port checks, HTTP and Wake-on-LAN
• Speed test and Wi-Fi link details

TERMINAL
• SSH, Telnet and raw TCP sessions
• A local shell on your phone
• USB serial console for routers, radios and dev boards

PRIVATE BY DESIGN
No accounts, no ads, no analytics. Everything HIKER records, including your location, stays on your phone.
