VibeSDR

Software Defined Radio

$2.99 · Designed for iPad

VibeSDR brings software-defined radio to iPhone: UberSDR, OpenWebRX & KiwiSDR receivers, a GPU waterfall, background audio, on-device decoders, Siri & CarPlay. VibeSDR is a mobile-first software-defined radio (SDR) receiver — and far more than a single-server client. It speaks multiple SDR server protocols and does its own demodulation of the raw IQ with a clean-room DSP engine. Pair that with a GPU-rendered waterfall, native background audio, on-device decoders and maps, plus voice and in-car control, for a genuinely great SDR experience on any iPhone — whatever receiver is behind it. WHAT YOU CAN CONNECT TO • Remote SDR servers — native support for UberSDR, OpenWebRX / OpenWebRX+, and KiwiSDR, all behind one interface, with a directory chooser in the instance picker. • Networked rtl_tcp — connect to a remote rtl_tcp server and VibeSDR demodulates the raw IQ itself. DISPLAY & WATERFALL • Custom GPU waterfall and spectrum, rendered with a Skia shader for a smooth, high-frame-rate display independent of the server. • Portrait and landscape layouts, ProMotion 120 Hz, haptic tuning feedback. • Classic colour palettes (GQRX, KiwiSDR, CuteSDR, SdrDx, OpenWebRX), VFO glow controls, and a spectrum backdrop image. TUNING & CONTROLS • VFO drum with inertia scrolling and a dual-drum waterfall zoom. • Full mode set — USB, LSB, AM, SAM, FM, NFM, CW — with passband sliders. • Noise reduction, noise blanker, squelch, AGC, volume and mute. AUDIO • Native audio engines running outside any WebView, so playback survives app suspension. • Background audio on both platforms. • Lock-screen, Now Playing, CarPlay and Apple Watch controls with frequency + station metadata and station/bookmark skipping. • AAC recorder with share sheet. VOICE CONTROL • Siri — "Hey Siri, tune VibeSDR" then a frequency, a station name, or a band; it tunes with the right demodulator and step, even in the background over headphones, CarPlay or the lock screen. DECODERS & MAPS • On-device decoders — RTTY, NAVTEX, WEFAX, SSTV, Morse, and speech-to-text. • Server maps — HFDL aircraft, digital and CW activity maps, fully embedded. STATIONS & BOOKMARKS • Instance picker directory across UberSDR, OpenWebRX/OpenWebRX+ and KiwiSDR receivers, with country flags, favourites and an auto-connect default. • Bookmark and band-plan search with live EiBi schedules. • Visual Tuning System (VTS) — nearby-station bar, band-crossing popups and station skipping. • Live chat, and Share a tuned station as a tappable deep link. NEW: DEEP LINKING • Tap a vibesdr:// link to connect straight to a receiver and tune to the shared frequency — no hunting through the picker. VibeSDR is free software under the GNU GPL-3.0, built by Stuart Carr with AI assistance from Claude (Anthropic). VibeSDR is a receiver client and is not affiliated with the SDR servers it connects to.
