About VibeSDR
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.

| Release info | Update on Oct 31, 2026 |
|---|---|
| Release notes | A smoother, fully buffered waterfall • Zooming keeps the history exactly as it was drawn while new lines fan in or out — no slices, stretching or black. A station moving while you tune draws one smooth trail. • The waterfall runs on a steady clock, and briefly speeds up while you tune or zoom (SPEED UP WHILE TUNING, on by default). • WATERFALL SPEED has six choices: MINIMUM, LOW, ECO, NATIVE, DEFAULT and SMOOTH. The speed only changes how fast it scrolls; frames are combined, so short bursts are not lost. • DATA (LOW, AUTO or FULL) in the SERVER section sets how much the server sends. • Scale stamps: after a tune or zoom, a thin copy of the old frequency scale with its time scrolls away with the history. Tap an old trace to tune to its own frequency. A big jump keeps the history instead of clearing it. • The waterfall waits for the sound, so what you see lines up with what you hear, Bluetooth included. • Tall screens keep more history. Fixes • Signed in as a server's owner, the sound no longer drops for a moment every four minutes. • On a VibeServer, a DAB receiver no longer switches to FM and back when your connection blips. • FM stereo on a VibeServer recovers by itself if it gets stuck as mush after a tune. • Zooming out on an UberSDR no longer smears the history; typing a distant frequency on a VibeServer no longer shows the wrong place for a few seconds. • Radios reached over rtl_tcp get offset tuning, so the DC spike never sits on your station. • The EiBi schedule falls back to last season's until the new one is published. Thanks to Gesiima and Kiko for reports and testing. |
