Below you'll find the publisher's own description, a quick spec sheet, and a short buyer-beware checklist so you know exactly what you're installing before tapping download.
Install Checklist
- Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
- File size is a light 3.28 MB, so it installs quickly even on modest connections.
- This build is signed by "Thomas Giudici" — always verify the developer name matches what's listed on the app's official store page before installing an update.
- After install, Android may prompt you to allow "Install from unknown sources" — approve only this one install, then revoke the permission in Settings > Apps > Special access.
- We link directly to the APK file or the publisher's repository; we do not modify the binary. Always run a virus scan after any sideloaded install.
About this app
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.

Frequently Asked Questions
Is Spectre free to download?
Yes. The APK file linked from this page is free. The developer may offer in-app purchases once installed, but obtaining the installer itself costs nothing.
What Android version does Spectre require?
Android 4.1+ or newer. Installing on older devices may cause crashes or refuse to install.
Is Spectre safe to install?
We link to the exact APK published by Thomas Giudici. We do not modify the file. Still, as with any sideloaded app, scan it with a reputable antivirus before opening it, and only grant permissions the app genuinely needs.
How do I update Spectre?
Install the newer version on top of the old one — Android will keep your data. If the signature differs, uninstall first (you may lose local progress).
Why is the app not installing?
Common causes: not enough storage, an older Android version than 4.1+, or a conflicting build already installed. Free up space, check your OS version, and uninstall any previous copy before retrying.
