Why Tersia
Since the revival, faith has spilled out beyond Sunday. Christians are gathering at worship nights, hikes, run clubs and socials, not just their own church's events. Running and funding those gatherings shouldn't take a spreadsheet, a Google Form and a bank transfer. Tersia brings it all into one place.
Fundraising
Ministry costs money: refreshments, a room, a coach for the pilgrimage. Tersia turns your community into a place people can give to, and keeps the admin off your plate.
Every community gets its own giving page. Supporters set up a monthly gift or give a one-off, and it renews without anyone having to chase it.
Share your giving link in a WhatsApp group, from the front of church or on Instagram. People give in a couple of taps, no account needed.
Sell tickets for retreats, socials and pilgrimages, or let people give what they can. Take the money in the app instead of chasing bank transfers.
Connect your account once with Stripe and payouts land directly with your community. Bank details stay with Stripe, never with us.
Every gift and ticket sale shows up in one dashboard, so you can see what's coming in and plan around it.
For group leaders
Most group leaders are volunteers stitching together five apps to run one event. Tersia puts the whole thing in one place.
RSVPs, approvals, tickets, reminders and calendar sync, without the forms and the spreadsheets.
Your community and events show up to Christians searching nearby, not just the people you already have.
Each event gets its own chat, so the main community chat stays clean and no one spins up another group.
Prayer requests, a daily prayer and community made for the church, not bolted on.
Communities come and go, names change, but the people are everything. Sign up and see the faces God is drawing to the same things you are this week, the people stirring something new in your community, so you can say hi before you even get there. We keep the exact event private; you just see the people.
Tag a post as a prayer request and it goes out to Christians across Tersia, not just your circle. People you have never met will tap Praying and lift up your intentions. You are never carrying it alone.
See gatherings near you on a map. People love this one.
See what you're interested in and what you're going to, at a glance.
Some of the best gatherings happen in people's homes. Hosts can keep the address private: you see the area, and the full location is shared only once you're accepted to attend.
Tap Going and it's added straight to your phone's calendar. Changed your mind? Tap Not going and it's removed again for you. No more double-booking, and no more forgetting.
Direct messages, community rooms and event chats, together.
Cleaner, less cluttered, and built to be finished, not doomscrolled. When you are done, you are done. You can also link an event right inside your post.
Set your default filters once and they stick.

Tersia has made it way easier for me to stay connected within catholic communities in london because of how simple the interface is and how it gives all the details i need to know about what's going on!

I moved to London for work and felt completely isolated spiritually. Within a week of downloading Tersia, I joined a boardgames night and a weekly dance class. Made friends that have become family through all these amazing social activities. This app literally changed my life.

Someone at St George's told me about Tersia when I was visiting London for a week. I checked it out and ended up meeting up with new Catholics and making friends I never would have met otherwise.

Tersia is for the whole Church. It is not for people who think it shouldn't be open to those discovering the faith, or who think any denomination shouldn't be welcome, whether that's 'only Catholics' or 'no Catholics'. We are unapologetically ecumenical, and everyone seeking Christ has a place here.
