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 â 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.

Verdict
The clearest difference is in-app purchases: HyperMedicus at none against Cairn's 3. HyperMedicus also leads on ads (none vs shown) and iOS requirement (13.0 vs 15.0). Cairn's advantage is update cadence (every 5 days vs every 2 weeks). On price and device support there is nothing between them.
