VibeSDR: A Mobile-First iOS and Android Receiver App for Remote SDR Servers and RTL-SDRs

Thank you to Stuart Carr (Stuey3D) for submitting news about his new software release, VibeSDR, a free and open-source mobile SDR client he has developed for iOS and Android. VibeSDR is designed to be touch-first rather than a desktop interface shrunk down to phone size. It is a fully native client for UberSDR, OpenWebRX/OpenWebRX+, and KiwiSDR with its own GPU-rendered waterfall and spectrum. It also supports local RTL-SDR dongles via RTL-TCP on both platforms and over USB on Android with no extra driver install required.

VibeSDR comes with a long list of features. The app has on-device decoders for RTTY, WEFAX, NAVTEX, SSTV, Morse, and FT8/FT4, plus access to server-supplied decoders, Leaflet-based HFDL and digital spot maps, FM stereo with RDS, a local bookmarks engine with daily EiBi schedule downloads, and full background audio. It also has band-aware blind tuning, where using lockscreen, headphone, or in-car media controls to tune across a band boundary automatically switches to the correct demodulator and step rate for that band and ITU region. The app also has Android Auto support with browsable bookmark and band plan lists and steering wheel tuning, and on iOS, it offers Siri voice commands to work around the current lack of full CarPlay approval.

Stuart is upfront and mentions that VibeSDR was AI vibecoded with Claude, hence the "vibe" part of the name. He notes that while he did not write code himself, he designed, extensively tested, and reported bugs over weeks of late nights. He notes that the app will always be free and open source, with full source and APKs available on the VibeSDR GitHub. He also plans to eventually list it on the App Store and Play Store for a fee of around £3 to cover store and development costs.
