Haeil is a to-do app for calmly organizing and clearing the tasks that keep rolling in. Capture what’s on your mind, place it where it belongs, and move through it one step at a time. Paper helps you group related tasks into focused pages, Schedule gives you a clear view of what’s tied to each day, and Wave helps you choose one Paper and work through it with steady focus. Even when your to-dos come in like waves, Haeil helps you clear them one check, one page at a time.

This app is in Korean only. A to-do app you check off straight from the home screen widget. Write a task, add the widget, and one tap finishes it without opening the app. No sign-up, no login. [Overdue tasks rise on their own] · The list sorts itself by how long each task has been put off · Tasks you wrote today sit quietly at the bottom · You never have to set priorities or pick a sort order [Home screen widget] · Small and Medium sizes · Tap the checkbox in the widget and it is done right there. The app does not open · A finished item disappears from the list after 3 seconds. Tap again within that window to undo [A gauge appears after 3 days] · A vertical gauge grows on any task left undone for more than 3 days · The longer it is overdue, the longer the gauge, reaching its maximum at two weeks · Badges change at 3, 7, 14, 21 and 30 days · Only overdue items stand out, so the list never turns into noise [You set the intensity] · Four levels: light, medium, strong, off · Turned off, gauges and badges disappear and it becomes an ordinary to-do list · Preview each level in Settings before choosing [Pick a gauge color] · 8 skins. Two are free to use from the start · Three unlock permanently with one rewarded ad each, up to one unlock per day · Three open by using the app on several days or by unlocking other skins first · Skins change color and texture only. The gauge length showing how long a task is overdue is the same in every skin [Everything stays on your device] · No sign-up, no login, nothing sent to a server · Tasks and settings are stored on the device and are deleted with the app · Works on iPhone and iPad, in light and dark appearance [About ads] To keep the app free, a full screen ad is shown when you open the app and when you return to it from another app. It is not shown the first time you run it after installing. There is no permanent banner inside the screen. The rewarded ad for unlocking skins plays only when you tap it yourself. The advertising identifier is used for this. This app does not scold you for putting things off. It just leaves the days visible. Contact: gogumaa619@gmail.com

Verdict
The clearest difference is ads: Haeil at none against 밀린 할 일's shown. Haeil also leads on iOS requirement (15.1 vs 17.0). 밀린 할 일's advantage is update cadence (every 3 days vs every 2 months). On price, in-app purchases and device support there is nothing between them.
