What it does
Multicultural and African churches in the UK run on WhatsApp. The church-wide community chat, the choir chat, the men's ministry chat, the youth chat and the prayer chain. Half of church life happens there. The problem is that nobody has the link to the one they actually need, and the leader spends every Monday morning resending invites to the new members.
ChurchLinker fixes that without trying to replace WhatsApp. You paste each group's invite link once into its settings. Members then see only the chats they actually belong to, right on their home screen, with one tap to open WhatsApp itself.
No Twilio account. No WhatsApp Business API to set up. Just the standard chat.whatsapp.com invite links your group leaders already have, surfaced where members will actually find them.
