Native SDR Client for iPhone

Listen SDR

Listen SDR is a native iPhone app for listening to public SDR receivers, designed from the ground up for blind and low-vision users.

It combines practical VoiceOver support, direct tuning, receiver-specific controls, and local recording in one focused radio client built for real listening sessions.

Built for accessibility

Listen SDR is designed for practical non-visual use: clear focus order, grouped controls, spoken feedback, Magic Tap support, and workflows that do not force the user to hunt through scattered UI elements.

Made for real listening

Tune live receivers, switch modes, work with bookmarks and band plans, reconnect quickly, and keep listening history and recordings on the device.

Native support for major SDR backends

Connect to FM-DX Webserver, KiwiSDR, and OpenWebRX receivers through one native iPhone interface instead of jumping between unrelated tools.

Why Listen SDR stands out

Built for VoiceOver

Listen SDR is intentionally shaped around VoiceOver use, not patched afterwards. Spoken state changes, grouped controls, and customizable feedback are part of the product direction.

Supports the major public SDR backends

The app works with FM-DX Webserver, KiwiSDR, and OpenWebRX, so one client can cover a broad range of public receivers and listening workflows.

Direct tuning and receiver control

Listen live audio, change demodulation modes, adjust squelch and receiver-specific settings, and move through bookmarks, bands, and recent frequencies with less friction.

Keeps listening local and practical

Store favorite receivers, keep recent history, export diagnostics when needed, and save recordings directly on the device for later listening or sharing.

Accessible by design

For blind and low-vision listeners

Core listening features

Why this is different from generic SDR clients

It is not only a network receiver browser

Listen SDR is built around actual listening sessions: tuning, reconnecting, keeping useful history, managing saved radios, and working directly with receiver-specific controls.

It respects backend differences

FM-DX Webserver, KiwiSDR, and OpenWebRX do not behave the same way. Listen SDR exposes the controls and flows that matter for each backend instead of flattening everything into a lowest-common-denominator UI.

Accessibility shapes the product

Accessibility is part of the product architecture. That changes focus order, action grouping, feedback design, and the structure of the receiver workflows themselves.

Built as a native iPhone app

Listen SDR is not a thin wrapper around a web page. It is a native client designed for iPhone workflows, iOS audio routing, VoiceOver, local recordings, and platform-native interaction patterns.
