For your church

A church home
of your own.

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.

How it works

Up and running in two simple steps

No technical know-how needed. If you can use a phone, you can use TrinityOne.

  1. 1

    A leader sets it up

    One person sets the church up — it's free, takes minutes, and there's nothing to host and nothing to configure.

  2. 2

    Everyone joins by tapping a link

    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.

All in one place

Your church's life, together all week

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.

God's Word, at the centre

A clear, beautiful Bible to read each day, with large, easy-to-read text — the heart everything else is gathered around.

Sermons & teaching

Listen back to this week's sermon whenever it suits, with notes that send you back into the passage.

Reading plans & devotionals

A little to read each day — gentle plans and devotionals to keep you in the Word.

Prayer & group chat

Live it out together through the week — share news, send a prayer, and carry one another.

Serving rotas

See who's serving each Sunday at a glance, so everyone knows when it's their turn.

Caring for one another

When someone is unwell or going through a hard time, it's easy to rally round — like organising meals so no one is forgotten.

Watch over the children

Young people are kept safe, with parents and trusted leaders looking out for them.

Giving Coming later

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.

Made for the Church, everywhere

One app, for the whole family of God

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.

Where it isn't safe

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.

A full week's life

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.

The three pieces

How it all fits together

A church leader sets things up, your messages live in one private home, and members join from their phones.

Church leader sets it up (groups, rotas) Your church's private home this is a relay holds all your messages (host your own, or we host it) Members the app on their phone Church leader sets it up (groups, rotas) Your church's private home this is a relay holds all your messages (host your own, or we host it) Members the app on their phone

Why a relay? →

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.

Why we built this

There are rooms where the Church meets in whispers

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.

Not a platform. A protocol.

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.

Private by design

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.

Not two products. One Church.

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.

What it does

Everything your church does, in one place

Everything below works today. Nothing here is a plan.

The Bible

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.

The conversations that keep a church close

Group rooms for your small groups and teams, announcement channels, and private messages. Prayer requests that people actually answer.

The rota in your pocket

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.

The whole church's week, in one place

Services, socials and meetings on one calendar, with RSVPs — so nobody misses the thing that was only mentioned once from the front.

When someone needs the church to show up

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.

When something happens, know everyone's safe

A steward asks the congregation to mark themselves safe, and sees at a glance who has answered and who has not.

Protection anchored in your leaders

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.

Host it yourself, if you want to

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.

For churches

Free for your church — at any size, for good.

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.

Free — for good

No subscription, no per-member fee, no tier to upgrade to. There's no company in the middle to bill you.

Your own relay — optional

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.

A community you can keep safe

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.

The admin, handled

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.

Get the app

Get TrinityOne

Install it on an Android phone, or just open it in your browser on any device — there's nothing to set up.

TrinityOne

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.

TrinityOne Steward

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.

TrinityOne Suite

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.

Ready when you are

Bring your church home.

Start a church today — it's free, and there are written guides for setting it up.
