Echo: Global SDR Receiver

Echo is a fantastic app for anyone interested in SDR, shortwave, ham radio, aviation, and global radio listening. The interface is clean, fast, and very easy to use, with access to thousands of remote SDR receivers around the world. I especially like the interactive map, background audio, scanner mode, and the ability to explore real radio signals directly from my iPhone or iPad. The app feels polished, privacy-friendly, and clearly built with care. A must-have for radio hobbyists and curious listeners alike! 📡🌍🎧

I have been wanting an app just like this for so long, use web SDRs often but this makes it so convenient to listen from the phone/on the go rather than on the computer. Even just for AM/FM listening it’s vastly superior to all the “radio” apps that seem to just use the web streams of stations rather than actual radio. Searched many times for an app like this since it just seemed like something that should exist, thank you for making it real!

This is such a great mobile interface to a world of radio. A lot of hard work was put into this app and it shows.
