Read the full description
BandSight is an Android app for receive-only spectrum viewing, supported radio listening, scans, and local radio records. It works with compatible RTL-SDR USB receiver hardware. Live reception requires a supported receiver, an antenna, and Android USB Host or OTG support. The phone alone is not the receiver. The app is free, with optional support; hardware compatibility and reception conditions determine available results.

Partial The Android UI for spectrum views, scanning, and recording is buildable with vibe coding. Reliable RTL-SDR support, USB driver integration, and DSP for demodulation require RF and low-level systems expertise and physical hardware for testing.
What it would actually take: Use librtlsdr via a native layer or JNI with Android USB Host APIs, then implement IQ sample streaming, FFT-based spectrum rendering, and demodulators such as FM and AM. The hard parts are real-time DSP performance on phones, tuning and calibration across devices, and driver compatibility, which require RF engineering knowledge and test hardware.
