ID vs BLE Sniffer

A secure contact book for the people you already know. The number on your screen can be faked, and an AI voice can sound like someone you know. With ID-Truster, you can check in seconds that a call or message really comes from the person you trust. YOU LOOK OUT FOR EACH OTHER Peace of mind is mutual. We rarely think we will be fooled ourselves, but we often worry about mom, grandpa, or a good friend. The best reassurance is the one you create together. Connect with family and friends so you share a common tool when something feels off. HOW IT WORKS - Connect once. You both choose "Add contact", and an encrypted connection is created between your phones. - A heads-up before the call. When a trusted contact calls you, you get a notification in the app just before your phone rings. So you know the call is genuine, no matter what the screen says. - Trust codes. Create a code in the app and paste it into any text message, email, or social media message. The receiver checks the code in the app and gets an answer in seconds. The code is locked to that receiver and expires by itself after 24 hours. ALONGSIDE, NOT INSTEAD OF ID-Truster does not replace your phone, email, or chat. It is an extra layer of reassurance that runs alongside what you already use. YOUR DATA STAYS WITH YOU The connection is encrypted with a key that only lives on your phones. We cannot see the names or phone numbers in your secure contact book, only the email address the account was created with. Everything is built to comply with GDPR. EASY FOR THE WHOLE FAMILY Most people are up and running in a few minutes. Each of you enters your name, email, and phone number, and you are ready to connect. The more of you who join, the better you look out for each other. ID-Truster is free for personal use and built in Denmark. Need help? Write to support@idtruster.com.

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.
