BandSight helps radio users and authorized site assessors view signals with a compatible RTL-SDR receiver. The browser app combines live spectrum and waterfall views, supported WFM/NFM/AM listening, named survey sessions, baseline comparison and local report export. The separate Android app adds band scans, saved stations and field tools. A phone alone cannot receive the spectrum: live radio use requires supported receiver hardware, an antenna and a compatible USB connection. The Android app is free on Google Play, with optional support; hardware and separately scoped services are extra. Product details and limitations: https://autosecurelogin.com/products/bandsight.html
