Cairn (차곡차곡) is a calm, anonymous-first todo app — every core feature works without an account. Like the small stones stacked into a cairn on a quiet trail, line up today's tasks one by one with clarity. ■ Core features - Anonymous by default: no sign-up, no transmission. All data stays on your device. - Inline markers: type @, #, !, * to set date, time, importance, and repeat in one line. e.g. "@tomorrow #3pm meeting", "*every-monday run". - Two-way swipe: left for reschedule / favorite / repeat. Right for duplicate / move group / delete. - Groups and color labels: organize by work, personal, fitness — at a glance. - Notifications with quiet hours: push reminders that auto-defer to the next morning during quiet hours. - Stats dashboard: weekly / monthly / yearly completion, 14-day sparkline, average completion time. - Backup & restore: JSON / CSV / Markdown export and import. Move devices safely. - Dark mode and three themes (Tica, Tally, Nudge). - English / Korean auto-detected. ■ Tracks - Anonymous (default): full core, on-device only. - Pro: ad-free — one-time purchase, yours forever. ■ What we don't collect No location, contacts, photos, microphone, camera, or health data. In anonymous mode, not a single byte leaves your device. ■ About Sobok — building small tools that add quiet order to daily life.
