BLE Sniffer
This app transforms your iPhone into a passive Bluetooth Low Energy scanner. It reveals nearby BLE devices, logs their advertisements, and offers a proximity radar to estimate distance, all without establishing a connection.
- Live BLE device scanning
- Device categorization with vendor lookup
- Proximity radar and Geiger mode
- Session saving and baseline comparison
- Full CSV export of scan data
- Optional GATT service inspection

BLE Sniffer turns your iPhone into a passive Bluetooth Low Energy scanner. See the BLE devices broadcasting around you, log what they're advertising, and use a proximity radar to gauge how close they are — all without connecting to anything. Think of it as a "sniff raw" mode for the Bluetooth Low Energy spectrum: capture the advertisements in the air, filter nothing, analyze offline. Whether you're mapping the BLE devices in your own home, auditing your gear, or reverse-engineering your own hardware, BLE Sniffer shows you what's broadcasting nearby. WHAT IT DOES Live device scanning See a real-time list of the nearby BLE devices that are advertising — name, identifier, signal strength (RSSI), manufacturer, service UUIDs, advertisement count, and first/last-seen times. Sort by signal, activity, name, or recency. Device categorization (heuristic) A built-in lookup of the complete Bluetooth SIG manufacturer registry — 4,000+ vendor IDs — plus vendor and name heuristics attaches a visual badge to some devices to help you triage a long list — for example dev boards, smart-home gear, and devices whose manufacturer ID or advertised name matches known camera vendors. These are best-effort guesses based on what a device broadcasts, not confirmed identifications. Proximity radar & "Geiger" mode A radar view plots advertising devices on concentric rings by signal strength. Pick one device and switch to single-device mode: a big live RSSI readout with color-coded background plus audio and haptic feedback that speeds up as the signal gets stronger — walk around and home in on it like a metal detector. Sessions & baseline diffing Save a scan as a named session. Capture a baseline in one location, scan another, and diff the two — see which advertising devices appear in the new scan but not the baseline. A quick way to narrow a long list down to what changed. Full CSV export Export any session or live scan as CSV — one row per advertisement, with timestamps, identifiers, RSSI, manufacturer IDs, service UUIDs, TX power, and raw advertisement bytes. Share it anywhere via the system share sheet for offline analysis. Optional device inspection For devices you own, opt in to connect and browse the GATT service tree — read manufacturer, model, and firmware info and explore characteristics. Connections are always explicit and per-device; the app never auto-connects. PRIVACY-FIRST BY DESIGN • Passive by default — it listens, it doesn't transmit or pair • No ads, no in-app purchases, no subscriptions • No telemetry, no accounts, no cloud — your data stays on your device • Everything is logged locally and exported only when you choose GREAT FOR • Mapping and auditing the BLE devices broadcasting in your own home or office • Hardware hackers, makers, and security researchers • Anyone curious about the invisible radio traffic around them PERMISSIONS BLE Sniffer asks only for Bluetooth access, which it uses to listen for nearby device advertisements. It does not pair, transmit, or request your location. Each device appears under an app-scoped identifier assigned by iOS — no hardware addresses are exposed. NOTE BLE Sniffer is a passive observation tool for the Bluetooth Low Energy spectrum. It detects Bluetooth Low Energy advertisements only — it is not a hidden-camera or surveillance detector and cannot find devices that don't broadcast BLE (including many cameras, and anything using Bluetooth Classic, Wi-Fi, or cellular). RSSI indicates rough proximity (distance), not direction, and device categories are heuristic guesses, not guarantees. Please use it responsibly and legally.

Verdict
The clearest difference is rating: BLE Sniffer at 5.0 against BlueNox BLE Scan's 4.6. BLE Sniffer also leads on update cadence (monthly vs every 10 months). BlueNox BLE Scan's advantage is ratings volume (16 vs 2). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
BLE Sniffer holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: BlueNox BLE Scan has 16 ratings behind it against 2, so its average is the more settled of the two.
BlueNox BLE Scan ships an update every 10 months, BLE Sniffer monthly. The most recent releases landed on October 24, 2026 and October 25, 2026 respectively.
