Most of what we feel passes without a mark. Cairn supports a quiet practice of noticing. A small contentment. A flash of irritation. A heaviness you can't name. Mark it in a second, from your Apple Watch or your phone. Reflect on it when you're ready. Each stone is a moment you can return to. How it works Notice a feeling. Mark it. One tap on your watch or phone places a stone. No typing needed. Capture takes seconds, without breaking the moment. Return to it. Cairn invites you back to reflect, at your own pace. The six stones No moment is good or bad. It just is. Cairn uses six categories drawn from an old taxonomy, named in plain language. Contentment. A settled, easy presence. Desire. A pull toward something. Aversion. Resistance or irritation. Restlessness. Keyed up and scattered. Heaviness. Dull and weighed down. Doubt. Uncertain and wavering. Over time, patterns surface No scores. No streaks. Cairn does not want your attention. It simply lays out what you noticed. Where contentment gathers. Where friction repeats. Small signals that were always there, now visible. Made for the watch Cairn starts on the watch. A complication puts capture one tap from any watch face. Tap, pick a stone, done. Your phone is where you reflect. Private by design Cairn has no accounts, no servers, no analytics, no ads, no third parties. Your moments live on your device and, if you use iCloud sync, in your own iCloud, never on ours. We cannot read them because we do not have them.
