Signal

Signal is an open-source communication application for Windows. It uses the Internet to support direct conversations between individuals and conversations involving groups. Its core purpose is to provide encrypted communications for people who need to exchange messages through a computer.

Messages can contain files, voice notes, images, and videos. Signal also supports voice calls between two people. It supports video calls between two people as well, giving users more than one way to communicate within the same application.

The product is listed in the Communication category because its functions center on messaging and calling. Windows users can use it for personal conversations or group discussions, depending on the type of communication they need. The open-source license identifies Signal as software distributed under an open-source licensing model.

MirrorNest distributes the official Windows build directly from its own storage. Before publishing, MirrorNest scans the mirrored build for malware.
