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.

Looks to be a handy sdr phone receiver once I get the hang of it. **Developer response:** Hi thank you for the feedback and I apologise for it freezing that shouldn't be happening, however since your review V10 has now been released and this is a HUGE update which should hopefully solve your issues. If it doesn't then if you could raise an issue on the GitHub page with your iPhone model and version of iOS you are running I will try to get to the bottom of it for you. Glad to know V10 is working for you now, and I've designed the app to be as simple as possible whilst remaining powerful and feature complete as I could without hitting licensing concerns for codecs etc so hopefully you will get the hang of it nice and quick. If you have any questions go to the VibeSDR website and click the Discord link and I will be happy to help. ### 4/5 — Doesn’t open *2026-07-30* Downloaded but app freezes on opening . ## Frequently asked questions about VibeSDR ### What SDR servers does VibeSDR support?

Yes, VibeSDR features native audio engines that run outside of any WebView, allowing playback to continue even when the app is suspended. It also supports background audio on both platforms. ### Does VibeSDR have ads? No, VibeSDR does not contain advertisements. It is a paid application. ### What decoders are included in VibeSDR?

This one-time purchase grants you access to all its features. ### What devices is VibeSDR compatible with? VibeSDR is available for iPhone, iPad, and Apple Watch. It supports ProMotion 120 Hz displays for a smoother visual experience. ### How often is VibeSDR updated? The latest version of VibeSDR is 10.0.1, which was last updated on August 1, 2026. Updates typically include new features and improvements. ### Can I control VibeSDR with my voice? Yes, VibeSDR integrates with Siri. You can use voice commands like 'Hey Siri, tune VibeSDR' followed by a frequency, station name, or band to tune the receiver. ## Version history (last 4 releases) ### 10.3.1 — 2026-08-18 Fixes audio that could fail to start. • On some connections the app could set up audio and immediately tear it down again, leaving a perfect signal and no sound. Often it worked on the next attempt, which made it hard to spot. • Connecting to an UberSDR receiver by its address on your own network could leave the app with no sound at all. The audio connection now falls back to a transport that reaches it, and if audio does stall the app re-introduces itself rather than retrying forever. • The app keeps its own record of what the audio path did, so a Diagnostics report says what actually happened. Nothing else has changed. ### 10.3 — 2026-08-17 Works with the new multi-radio VibeServer. Connect once and choose any receiver on the server. The picker shows which are free and which are in use before you commit to one. • Sign in as the owner to take a receiver back from any device — the most recent login wins, and the other side is told why • Your remembered frequency comes back with you on reconnect • RDS station bookmarks are shared with the server • Alternative frequency lists, IF bandwidth and CEQ are now shown in full • Fixes for tuning, reconnection and audio dropouts ### 10.0.1 — 2026-08-01 A big one — four releases in one. FM-DX tuner support. Connect to FM-DX Webserver receivers worldwide, with full RDS, station identification and a tuning dial. VibeServer. Run your own SDR as a server on a Mac or Raspberry Pi and listen from anywhere — RTL-SDR, SDRplay RSP and Airspy HF+ supported. VibeSDR Buddy for Apple Watch. Control VibeSDR from your wrist with Buddy, the included watch app — the waterfall, DAB and aircraft screens, all on the watch itself. Better RDS. The decoder has been calibrated against a professional reference analyser and now reads far more stations, further out. Also: iCloud sync for your favourites and bookmarks, a recordings browser, DAB and ADS-B, keyboard control, and a great many fixes. This update also fixes the decoder window on smaller iPhones, where its controls could be cut off, adds menus for the spot filters, corrects SSTV image alignment, and makes VibeSDR a better guest on shared receivers — honouring each server's own session limits and warning you before one times out. ### 6.1 — 2026-07-14 No release notes. ## More apps by Stuart Carr - [VibeSDR Jr](https://appshunter.io/ios/app/vibesdr-jr/id6795507029) All apps by Stuart Carr: https://appshunter.io/developer/6786344051 ## Related topics [transistor radio](https://appshunter.io/ios/topics/transistor-radio) · [cv radio](https://appshunter.io/ios/topics/cv-radio) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
