For the people who run the group
You were called to lead, not to chase RSVPs across five apps
Most group leaders are volunteers. Tersia puts your events, sign-ups, payments, prayer and people in one place, so running your community stops feeling like a second job.
A real story, from a parish priest
He runs the young adults group. To put on one event or pilgrimage, here is his actual workflow:
Six or seven tools, stitched together by hand, for every single event. It is stressful and it eats hours he does not have.
“I signed up to be a minister for Christ, but I'm drowning in paperwork.”
That is the problem Tersia exists to solve.
One app instead of seven
Everything that workflow does, in a single place built for it.
Today, juggling
- WhatsApp for chat
- A new group chat for every single event
- A 1024-person cap that splits a growing community across overflow groups
- Copy and pasting every event into group after group to promote it
- The same groups reaching the same people, never anyone new
- Google Forms for sign-ups
- Email for approvals
- A spreadsheet to track who is coming
- Bank transfers chased by hand
- Instagram / TikTok to promote
- Nothing talks to anything else

Built for people who run things
Events that run themselves
RSVPs, approvals, payment, reminders, calendar sync. No forms, no chasing.
People find you
Your community and events show up to the right people nearby.
A chat for every event, automatically
No spinning up a new group chat each time, and no muddying the main community chat. Every event comes with its own dedicated chat, so the right conversation stays in the right place.
Faith at the centre
Prayer and community chat made for the church, not bolted on.
Your group grows while you sleep
A WhatsApp group is a locked box, the only way in is a link you remember to share. On Tersia your community is discoverable: people nearby and people searching for a group like yours find it and join.
WhatsApp: closed
- Invisible, no one can find it
- Grows only when you share a link
- New people need to know it exists first
Tersia: discoverable
- Shows up in discovery and on the map
- People searching for a group find yours
- They request to join your chat in a tap
Every event you post is a front door: someone discovers the event, then discovers the community behind it.
And yes, it replaces these too
The tools you are stitching together, in one comparison.

Run your next event in one place
No forms. No chasing. No lackey work.
Bringing your community across also helps Christians discover yours, and groups like it. Since the revival, people aren't looking to attend just their church's events. They're open to gatherings across different churches and places, as long as they get to meet other Christians. Add your community so the thousands of believers searching can find their way to you.
Common questions
Is this open to Catholics?
Yes. Tersia is built for the entire Christian community, Catholics very much included. Parishes, young adults groups, prayer groups, faith and fitness groups and pilgrimages all run on it.
Is this for all Christians?
Yes. Whatever your tradition, if you gather as Christians, Tersia is for you. We focus on the things every Christian community shares: events, prayer, staying connected and above all Jesus.
