KiwiTuner live spectrum and waterfall tuned to 6.005 MHz AM

Made for signal hunters

Everything between the antenna and your ears.

Fast enough for band scanning, detailed enough for deliberate listening, and built around how radio actually works.

Live spectrum & waterfall

Watch signals emerge in a smooth viridis waterfall. Tap to tune on a 0.5 kHz grid, drag across the band, or pinch all the way down to a 500 Hz-wide view.

Find what is on now

Browse the EiBi shortwave schedule, filter broadcasts by region and type, keep favorites at the top, and tune without leaving the list.

Fresh amateur spots

Follow Spothole spots with instant search and filters for Phone, CW, Data, POTA, SOTA, WWFF, WWBOTA, and more. Tap any spot to tune.

Receivers around the world

Choose from recently verified public receivers or add your own. Server-specific passwords stay protected in the iOS Keychain.

See the path

A monochrome radio map places receivers and transmitting stations in context, with an animated path between them.

Shape the sound

Adjust spectrum smoothing, tame harsh highs with the optional high-cut filter, and move between stations with gentle audio transitions.
