Built around God's Word, with everything else your congregation needs — sermons, devotionals, prayer, serving, and care, in one private app.
Free to start, and always free to use.Always free to use — we're bringing pilot churches on by invitation right now.
No technical know-how needed. If you can use a phone, you can use TrinityOne.
One person sets the church up. Free, takes minutes, nothing to host or configure.
One link or QR code. No forms, no password, no email — just twelve words to keep somewhere safe. Some churches ask a steward to let you in first.
Scripture is the heart of it. Everything else here — the way you gather, pray, serve, and care — simply draws you back to time in God's Word together.
A clear, beautiful Bible to read each day, with large, easy-to-read text — the heart everything else is gathered around.
Listen back to this week's sermon whenever it suits, with notes that send you back into the passage.
A little to read each day — gentle plans and devotionals to keep you in the Word.
Live it out together through the week — share news, send a prayer, and carry one another.
See who's serving each Sunday at a glance, so everyone knows when it's their turn.
When someone is unwell or going through a hard time, it's easy to rally round — like organising meals so no one is forgotten.
Young people are kept safe, with parents and trusted leaders looking out for them.
Giving from your own wallet, landing straight with the church — being built, and not in the app yet. The treasurer's optional ledger for recording giving is here now.
A church leader sets things up, your messages, events and content live in one private home spread securely over a network of relays, and members join from their phones.
The leader sets the church up; members connect to that same home.
In much of the world, gathering as believers is ordinary. For many of our brothers and sisters it is not — every account, every message, every list of who-belongs can be watched, demanded, or used against them.
We could not build for the comfortable Church and quietly leave these believers out. We built for them first.
A tool forged for the persecuted Church turns out to be good for the Church anywhere. The same app serves believers meeting quietly where it isn't safe to be online, and a church with a full Sunday rota and a serving team — kept private to your church either way.
A platform is something you join — a company owns the servers, holds your data, sets the rules, and can lock you out tomorrow. A protocol is something you run, like email. TrinityOne is a protocol: you hold your own keys, you can host it yourself, and there is no "in" for anyone to shut you out of.
No email or phone number to sign up. Direct messages are encrypted, group rooms can be, your members' names are sealed so the relay stores only ciphertext it cannot read, and safeguarding for children is enforced by the server — not just hidden in the app.
A church with steady internet and no fear of the door can run TrinityOne on its own small computer — and from that same box offer a home to churches that could never run one. Bandwidth you already pay for becomes somewhere else's Sunday.
Everything below works today. Nothing here is a plan.
A full Bible the moment you open the app. Hundreds of translations to download and alongside them open study notes, commentaries, Greek and Hebrew lexicons and early Church writings.
Group rooms for your small groups and teams, announcement channels, and private messages. Prayer requests that people actually answer.
Services, socials and meetings on one calendar with RSVPs, so nobody misses the thing mentioned once from the front. See when you're next on, swap with a teammate, and set the days you're away — with reminders that reach you on Android with the app closed.
A new baby, a hard week, someone home from hospital — the church opens a need for meals, rides, errands or visits, and members sign up day by day.
Built to support the safeguarding you already have in place, not to replace it. And if there is an emergency, a steward can ask the congregation to mark themselves safe.
A church can hold its own messages, members and records on hardware in the building. Or use ours, and move later without anyone losing anything.
Rotas, the member list, groups, the calendar and safeguarding — the whole life of your church, with no subscription and no per-member cap. You can move it onto your own hardware at any time, which is why nobody can start charging you for it later.
No subscription, no per-member fee, no tier to upgrade to. There's no company in the middle to bill you.
Your church runs on TrinityOne's shared relays out of the box, with nothing to set up. Want a copy of every event on hardware you control? Run the free Relay app on any Mac, Windows or Linux machine. It falls back to the shared relays unless your church chooses to run only its own.
Mark who is a child and who is cleared for youth work, and the rules apply automatically — enforced by the relay rather than the app. Invite-only groups, and a blocklist only the owner can write.
Joining codes and a printable invite poster, member approval, serving rotas, the calendar, and a treasurer's ledger with quarterly statements that share totals without naming anyone.
Install it on an Android phone, or just open it in your browser on any device — there's nothing to set up.We're not open to the public right now.
We're bringing pilot churches on by hand right now — email us and we'll get you set up.
Already part of a church using TrinityOne? Install from your church's own link — not from a file someone sends you.
Read the Bible, join your groups, pray together, and keep up with your church through the week.
The Bible works straight away. To join your church you'll need their invite link or code.
For pastors and church leaders. The whole church on a computer you own: your records stay on your machine, and the console to run it comes with them — one double-click app, no command line.
The way we'd point you. Any computer you can leave on will do.
Setting up a Linux server with no screen, or stuck on a Linux package? Running your own relay
Open TrinityOne Steward, the console pastors and church leaders run their church from, in your browser instead. Nothing to install, and you can move to the Suite later — but your church's records will live on our relays rather than your own.
Download the app from this page, or from your church's own TrinityOne address.
Caution: if someone sends you the app, even someone you trust, don't install it. A file can be changed on its way to you without you knowing.
TrinityOne is free and open source, always. Some churches are well equipped with technology, some have very little.
Share a computer that stays on. One machine can hold more than one church.
An old computer in a cupboard will do. The Suite is one double-click app, easy.
A friend, your small group, your pastor. Every church that joins makes the network stronger for all of them.
