Key features • Three spaces: Quick / Work / Home • Today’s progress and completion record • Review unfinished tasks from yesterday • Backup export and import • Korean and English support • Save and share Oneulchi Cards Oneulchi PLUS A one-time purchase for permanent access. • Today’s Routines to save and reuse recurring tasks • Home Screen widgets • Daily and weekly reports • Additional paper themes • List icons and app icons • Additional card styles No login or account is required, and your task data stays on your device.

Verdict
The clearest difference is update cadence: Proof at every 2 days against 오늘치's every 10 days. 오늘치's advantage is iOS requirement (15.1 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.
