Cairn is a personal project that isn't in active development right now. I still read this inbox, but replies may be slow.
Each morning you set one word for the day. Each evening you can add one sentence reflecting on it. That's the whole ritual — small on purpose.
Yes. Cairn syncs through your own private iCloud account, so your words appear on your iPhone and Apple Watch. Make sure you're signed into iCloud and that iCloud is enabled for Cairn in your device settings.
Sync between devices can take a moment, especially right after installing. Make sure both devices are on the same iCloud account and connected to the internet. Opening the app on each device helps it sync sooner.
Completely. Cairn collects nothing — no analytics, no tracking. Your entries live only on your device and in your private iCloud, which we can't access. See the Privacy Policy.
Long-press your Home Screen or Lock Screen, tap the + (or Customize), search for "Cairn," and add the widget you'd like.
Deleting individual entries is done inside the app. To remove everything, delete the app and remove its data from iCloud in your device's iCloud settings.
