GhostFreq

GhostFreq turns Apple Watch into a compact Bluetooth Low Energy field scanner for developers, makers, and hardware testers. Start a scan from your wrist, sort nearby peripherals by signal strength, and connect to devices that expose GATT services. GhostFreq lets you inspect advertised services, UUIDs, service names, characteristics, properties, and live RSSI without reaching for a laptop. Features: - Scan nearby BLE peripherals - View device names, RSSI, signal bars, and connectability - Connect and browse GATT services and characteristics - Read characteristic values as HEX and UTF-8 - Subscribe to notifications and indications - Write UTF-8 text or HEX payloads to writable characteristics - Add complications for discovered device count, connected device status, and signal strength GhostFreq is designed for local Bluetooth diagnostics. It does not require an account, does not use a server, and does not collect personal data. It only uses Bluetooth on your Apple Watch to discover and interact with nearby BLE peripherals you choose to inspect. Note: GhostFreq works with Bluetooth Low Energy peripherals. Classic Bluetooth devices that do not expose GATT services may not be inspectable.
