Echo 1.2 brings complete compatibility for iOS 27 and a massive rebuild of OpenWebRX support. If you use OpenWebRX receivers, you'll notice a much smoother, faster experience.

Receivers now open almost instantly thanks to smarter interface caching. • Fixed an issue preventing receivers from loading correctly on iOS 27. • Map, chat, help, and status links within the receiver interface are now fully functional across all server types. • Added a dedicated back control to easily return to the radio from secondary pages. • Added a new MENU control in the player header to toggle the receiver's native top bar, giving you more screen space when you want it. • Fixed an issue where some servers would incorrectly switch tuning modes during connection. OTHER RECEIVERS • KiwiSDR: Resolved an issue that could cause the receiver to continuously reload. • WebSDR: Fixed precision tuning for fractional kHz frequencies, ensuring SSB and CW signals come in crystal clear. AUDIO • Audio reliably resumes after interruptions like phone calls or Siri. • Updated the core audio engine for full iOS 27 compatibility. EVERYTHING ELSE • Fixed an alert on some stations that could not be dismissed. • Notes on saved servers now reliably persist between app sessions. • Updated the offline shortwave frequency database for the A26 season. • Refreshed the hot list. • Streamlined the interface by removing legacy SNR sorting and badges. • Visual refinements and UI cleanups throughout for iOS 27.

About
Echo is the ultimate, natively-built iOS client for tuning into remote radio servers. Listen to anything, from anywhere. Dive into international shortwave broadcasts from Asia, monitor aviation communications over the Atlantic, discover mysterious numbers stations, or tune into distant FM stations across the globe, all from your iPhone or iPad. Featured in Radio World, on RTL-SDR.com, and in the SWLing Post. Radio World's Nick Langan praised Echo's "thoughtfully designed interface" and called it an app he has "loved using."
