Cairn: Gratitude Journal

Cairn is a gratitude journal for iPhone built around one small nightly habit: before bed, write down three good things from your day. It deliberately leaves things out: no prompts, no mood scores, no streak counter and no guilt-trip notifications. Miss a night, or a month, and your journal is still there when you come back. Every entry goes into an archive you can browse by month, and each night Cairn shows you what you wrote a year ago tonight. Writing your three things is free. A one-time unlock (no subscription) adds voice entry, full archive search and export, and a home and lock screen widget. Built as a native iPhone app. No account, no ads, and the App Store privacy label is Data Not Collected.
