A journey. A rock.
A cairn that grows.

Cairn Memories is built around a simple three-part metaphor. Each part maps to a real experience — from the moment you leave home to the memory that a grandchild discovers fifty years from now.

Three words. One platform.

Moment

A single capture during a journey — a photo, voice note, text entry, video clip, ambient audio, or GPS track. The building block of everything.

Rock

Your complete journey — the full arc from departure through arrival through experience, composed of the moments you captured along the way. Your contribution to any cairn.

Cairn

A collection of rocks, built by many hands over time. The organizing structure that gives individual journeys their collective meaning. Private, event, or shared.

From doorstep
to cairn in five steps

1

Set up your journey

Before you leave — or right when you step out the door — open Cairn Memories and start a journey. Tell us where you're headed (optional), who you're capturing for, and how actively you want Rocky to check in. The whole setup takes under a minute.

You can plan ahead and schedule a journey start for a future date. Or tap "Start Now" and be capturing within seconds.

2

Capture as you travel

Rocky, your AI journey companion, wakes up and begins paying attention. He checks in at natural moments — when you arrive somewhere new, when you've been still for a while, when the cairn's history connects to a place you're visiting — but never so often that he becomes the trip.

You can capture through the Dynamic Island without opening the app, through Rocky's chat, through the Share Sheet from any other app, or by asking Siri to "add to my journey." Every capture source feeds the same rock.

3

Review your moments

As your journey unfolds, your moments accumulate in real time. At any point you can open the rock's moment list and review what's been captured. The AI groups related captures — a photo and voice note taken within a few minutes — into coherent moments automatically.

Split moments, merge them, add captions, highlight the ones that matter most. Or leave it alone and let Rocky handle the organization.

4

Finalize your rock

When your journey ends, complete your rock. Rocky prompts a brief reflection — a few words about the trip that will live alongside your moments. Set keys if you want some content to reveal at a specific time or place. Choose privacy settings for each moment.

Your rock is ready. Now decide where it lives.

5

Place your rock on the cairn

A single rock can be placed on multiple cairns simultaneously. Place it on your family's Private Cairn, the wedding Event Cairn, and a shared destination cairn — all at once, with different captions and visibility for each context.

Your rock is yours. The cairn is everyone's. And the story it tells can only be told by everyone together.

Under 60 seconds
to start capturing

Journey setup is lightweight by design. You can start capturing in under a minute with just two taps. Everything else — destination, recipients, cairn placement — can be filled in while you're on the road or after you return.

  • Quick Start: Start now with rock type + capture density
  • Planned Start: Configure in advance, auto-activates when you leave
  • Recipient targeting: Specify who this rock is for so Rocky can prompt accordingly
  • Adjustable at any time: change settings mid-journey without interrupting capture
