BandSight

Explore radio signals with BandSight, a native Android receiver for compatible USB RTL-SDR hardware. Tune a frequency, scan a band, inspect supported signal bursts and keep your own library—all on your device.

A RECEIVER IN YOUR POCKET
• Connect an RTL2832U + R820T2 USB receiver using a compatible OTG adapter.
• Tune supported frequencies with wideband FM, narrowband FM and AM audio.
• Use band presets, scan for signals and view the spectrum.
• Follow signal strength with the signal finder.
• Record received audio and export the completed WAV file.

BUILD YOUR SIGNAL LIBRARY
• Save and favorite stations.
• Inspect supported OOK/ASK bursts on the 315, 433.92, 868 and 915 MHz ISM presets.
• Organize captured signals into device and button libraries.
• Import and export saved stations and signals as CSV.
• Read searchable help and privacy information offline in English or Spanish.

THE ASL DESIGN
The original rBroker splash artwork, the Auto Secure Login website lock and an animated blue background bring the ASL design to BandSight. Jump directly to the receiver, saved library or help. Animation respects reduced motion and battery saving.

OFFLINE BY DESIGN
BandSight has no internet permission, account sign-in, ads or analytics. Your saved stations, signals and recordings stay on your device unless you choose to export them. The Android file picker handles your chosen export destination. An optional support link opens your browser; tips never unlock features.

HARDWARE REQUIRED
Radio reception needs a compatible USB receiver, antenna and USB OTG connection; these are not included. Some phones require a powered USB hub. An RTL2832U + R820T2 receiver covers roughly 24–1766 MHz with a suitable antenna. BandSight does not turn a phone's built-in Wi-Fi, Bluetooth or cellular radio into a wideband receiver.

RECEIVE ONLY
BandSight has no transmit path. It does not replay remote-control codes, unlock devices or decrypt encrypted communications. Use equipment and signals you are authorized to examine, and follow the rules for reception, recording and sharing in your location.

Android 8.0 or later. USB Host support required.
