## What is Cairn Journal?

Your thoughts never touch a server. Voice, mood, and patterns are analyzed entirely on your device with Apple Intelligence — no account, nothing uploaded.

Raise your Apple Watch and say whatever's on your mind. That's a journal entry. Cairn transcribes your voice, senses your mood and energy, and quietly builds a picture of your hidden inner feelings over the weeks and months.

THIRTY SECONDS, NO BLANK PAGE
No typing, no prompts to fill in. Just talk for half a minute and you're done — before the thought slips away.

READS THE MOMENT, NOT JUST THE WORDS
On-device AI listens to what you said and how you said it, estimating mood and energy for every entry automatically. Over time, weekly insights and pattern alerts (with a subscription) reveal what lifts you, what drains you, and how your weeks really feel.

YOUR BODY, IN CONTEXT
With your permission, Cairn pairs each entry with heart rate and heart-rate variability from Apple Health — a quiet layer showing how a moment felt in your body, not just your head.

PRIVATE BY DESIGN
Your thoughts never touch a server. Voice recognition, mood analysis, and pattern detection all run on your device with Apple Intelligence. Nothing is uploaded, sold, or mined — and there's no account to create.

MADE FOR THE WRIST
Built for Apple Watch first, with an iPhone companion for reviewing, searching, and exploring your entries — plus Home Screen and watch complications to start an entry in a single tap.

FREE TO USE
Download and journal for free: up to 3 voice entries a week, with on-device mood and energy analysis included.

CAIRN CORE & PRO (OPTIONAL SUBSCRIPTION)
• Core — unlimited entries, weekly insights, and pattern alerts
• Pro — everything in Core, plus managed cloud AI for languages Apple Intelligence doesn't yet cover

Subscriptions are auto-renewable, offered monthly or annually. Payment is charged to your Apple Account at purchase and renews automatically until cancelled; manage or cancel anytime in Apple Account settings.
