Available for Windows and Android. Guests joining a call need nothing installed — a browser link is enough.
⚠ Windows will show an “unknown publisher” warning
Our Windows installers are signed with our own certificate rather than one bought from a commercial authority, so Windows SmartScreen does not yet recognise us. This is expected.
To continue: click More info, then Run anyway. If you would rather verify first, the signature is issued to RN Technologies and is timestamped by DigiCert — check it under the file’s Properties → Digital Signatures tab before installing.
