Ardea for iPhone

Private by nature.

See how it protects you
The Chats screen: a list of conversations, some marked with a green shield to show the person has been checked.
A group chat about a facilities review, with its plan pinned at the top.
The calendar's week view, with the day's plans.

Everything you'd expect from a messenger. Except anyone else reading it.

Chats

Every conversation, sealed.

Words, photos, voice messages and files are sealed before they leave your phone. Groups, favorites and disappearing messages work the way you'd expect.

In a chat, the + sheet for sending photos, files, plans and more.

Calls

Know who's really on the line.

Voice and video, sealed end to end. Each of you reads out two words. If they match, nobody is listening in.

A call in progress: your two words to read aloud, the two words the other person should say, and buttons for Matches and Doesn't match.

Calendar and plans

Plans that live with the conversation.

Pin the camping checklist or the agenda to a chat. Everyone sees the same list, and your calendar keeps it all together.

A personal plan for a camping trip, with a shared checklist.

Your phone

Locked, even when your phone isn't.

Ardea opens with Face ID or your own PIN. Notifications only wake the app, so your words and names never pass through Apple.

Ardea Lock

Two locks on every seal.

Every message is sealed with long-proven encryption and with new encryption built to resist future quantum computers, together, every time. If one is ever broken, the other still holds.

How Ardea protects you
  • 2kinds of encryption on every message, always both
  • 0messages our servers can open
  • 12plain words to check you're talking to the right person

The small things add up.

  • Checked, not trusted.

    Scan someone's code in person, or compare twelve safety words, and Ardea marks them as checked with a green shield.

    A contact page showing the person was verified from their scanned card, with a safety phrase marked as checked.

  • Disappearing messages.

    Set a chat to clear itself after a while.

  • No ads. No tracking.

    Nothing about you is sold or followed across other apps.

  • Home and work, apart.

    A Personal and a Work account side by side, never mixed.

  • Quiet notifications.

    They wake the app and carry nothing else.

Ardea for teams

Work together, in rooms.

A room keeps a piece of work together: its chat, files, plans and people. Before a report goes to another team, Ardea shows exactly who will be able to open it.

How teams work together
The Rooms tab, listing pieces of work with their open items.
Before sending a report: a list of the five people at the other team who will be able to open it, and whether each is verified.
The Ardea emblem: a heron rising inside a flame, above a glowing ember.

The name

Why a heron.

Ardea is Latin for heron. In Ovid's telling, when the old city of Ardea burned, a heron rose out of its ashes and flew up over the ruins. Something steady and alive, coming out of the fire. It's what we want for your conversations, whatever is going on around them.
