God's Word at the heart of it all — and around it, everything your church needs to live it out together: sermons, reading plans, devotionals, prayer, serving rotas, and caring for one another, in one app. Private to your church — no account, no password.
Free to start, and always free to use.
Joining a church? Have the invite link or code from your church to hand — that's what connects you to them.
No technical know-how needed. If you can use a phone, you can use TrinityOne.
One person sets the church up — it's free, takes minutes, and there's nothing to host and nothing to configure.
The leader shares one link or QR code. Tap it and you're through — no forms, no password, no email address. Some churches ask a steward to let you in first, and you'll be given twelve words to keep somewhere safe.
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.
From believers gathering quietly where it isn't safe to be online, to a church with a full Sunday rota and a serving team. The same app, kept private to your church.
For the persecuted Church, this is a quiet, private place to gather. Nothing is held by a big company that could be forced to hand it over or switch it off. It works over the thinnest connection, and a church can hold it on its own server if it has to.
For the well-resourced church, it's the whole week in one place: the Bible, groups, prayer, this week's teaching, serving rotas, watching over the children — with member giving on the way.
Keeping things private to your church is how we keep persecuted churches safe — and it protects everyone else along the way.
A church leader sets things up, your messages live in one private home, and members join from their phones.
The leader sets the church up and it flows into your private home. Members connect to that same home to read along and take part.
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.
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, in clean book-quality type, working entirely offline. Highlight like a real marker, and add the Strong's edition if you want original-language roots. Over a thousand translations to download.
Group rooms for your small groups and teams, announcement channels, and private messages. Prayer requests that people actually answer.
See when you're next on, accept or ask a teammate to swap, and set the days you're away. On Android, reminders reach you with the app closed.
Services, socials and meetings on one calendar, with RSVPs — so nobody misses the thing that was only mentioned once from the front.
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.
A steward asks the congregation to mark themselves safe, and sees at a glance who has answered and who has not.
Your church decides who is a child and which adults are cleared for youth work — not a meaningless tick-box. The relay enforces it, so a modified phone can't get around it.
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.
For every member — 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 the invite link or code they shared with you.
The console to set up and run your church — groups, rotas, members and the church's life. You only need it once per church, and it is best on a computer.
Optional, for churches that host their own: your own relay and the Steward console in one double-click app — no command line.
Download the app from this page, or from your church's own TrinityOne address. If someone sends you the app as a file — even someone you trust — don't install it. A file can be changed on its way to you, and your phone can't tell the difference the first time.
Start a church today — it's free, and there are written guides for setting it up.
Free to use, with guides and a help section built into the app.
