Spectre is an Android app for observing and interacting with the wireless environment around you.
It monitors signals from Bluetooth devices, Wi-Fi access points, cellular towers, and GNSS satellites.
Spectre also features a growing set of pentesting tools, constrained by Android's security model.

Features:
• RF exposure - total received power from cellular, Wi-Fi, and Bluetooth as one live dBm reading
• Cellular - serving and neighbor cells on 5G, 4G, 3G, and 2G, across both SIMs
• Wi-Fi - 2.4, 5, and 6 GHz access points, with security analysis and 802.11mc FTM ranging
• Bluetooth LE - advertising devices with decoded manufacturer data, including iBeacons
• GNSS - multi-constellation, dual-frequency satellite tracking with live sky geometry
• Local network scan - discover hosts, open ports, and running services on your network
• GATT inspector - connect to a BLE device to read, decode, and write its characteristics
• iBeacon broadcast - advertise your phone as a configurable iBeacon
• Filter and sort - focus the Wi-Fi and Bluetooth lists on specific devices

Spectre requests location and other permissions only because Android gates these signals behind them.
Everything runs on-device, with no ads, trackers, analytics, or Google Play Services.
Network access is used only to probe devices on your own local network.
