Common questions

Common questions

What is EchoBay?

A shared online island for friends. Talk in voice rooms, watch screen shares in a screening room, and leave voice notes. Island owners and admins can arrange buildings and decorations.

Can I watch a shared screen while talking?

Yes. Join a screening room voice call, then choose to watch. Shared sound and voice have separate controls, and leaving the screen share keeps you in the call.

Can I watch on my phone?

Supported mobile browsers and the Android client can watch. Share from Windows or a desktop browser with screen capture support. Availability depends on your device and network.

How do I install EchoBay on Windows?

Run the versioned Windows installer and choose a location. Existing installations keep their original location; supported versions also offer updates inside the app.

Why might Windows show an unknown publisher warning?

The Closed Beta installer does not yet have a commercial code-signing certificate. Download only from downloads.echobay.club and verify its SHA-256 if needed.

How do I install the Android APK?

After downloading, Android may ask you to allow installs from your browser. EchoBay never asks you to disable device security and is not distributed through third-party download sites.

Can I use EchoBay without installing it?

Yes. Open the web app in a supported desktop or mobile browser. Your browser will request microphone access the first time you join voice.

How do I join a friend's island?

Open their share link or enter the short code, preview the island, and confirm the visit. This does not replace your home island.
