About Solin

Solin helps with the operational side of congregation meetings — projecting media to the secondary screen. Songs, videos, images from the meeting, browser content — that kind of thing.

It is a desktop application. You run it on the computer connected to the projector or TV, so whoever is at that seat can feel comfortable handling the media.

A brother, working on his own. There is no organization or official body behind this — and it is not endorsed or affiliated with Watch Tower Bible and Tract Society of Pennsylvania or any related entity.

It is free, and that is not going to change.

The main Solin installers are intended for Windows 10 or later and macOS 13 or later.

Windows or your browser will probably show a warning saying the file comes from an unknown publisher. On macOS, the system may say the app is damaged or cannot be opened. That happens because Solin does not have paid code-signing certificates for Windows and macOS — the kind that tells the operating system who signed the file. Getting and maintaining those certificates for both platforms involves a costly yearly fee that does not make sense for something like this.

The warning is about identity. It just means the operating system does not recognize the name behind the file, not that anything is wrong with it. If you want to verify for yourself, you can scan the file on VirusTotal before running it.
