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

You forget things you wrote down because you never open the note again. Peekmo keeps short notes on your Lock Screen and in a Home Screen widget. Recycling day, a family birthday, taking your medication — the things you know but keep missing, back in front of you every time you pick up your phone. Write it, and it is on the widget One input field sits above the list. New notes are pinned by default, and only pinned notes reach the widget. No folders, no tags, no formatting — this app is the few lines you must not forget. Seeing notes on the Lock Screen · Lock Screen widget — press and hold the Lock Screen, tap "Customize" and then "Lock Screen", and add the Peekmo widget under the clock · Home Screen widget — press and hold an empty spot on the Home Screen and add it there · Pinned notes also stay visible in StandBy and on always-on displays Notes stay on the device No account, no server. Notes never leave the device, and deleting the app deletes them with it. Only the minimum is collected automatically: crash diagnostics (Firebase Crashlytics) and banner ad delivery (Google AdMob, non-personalized). No tracking. Free, with a banner ad Every feature is free. One banner ad sits at the bottom of the home screen. Privacy policy: https://cottonray.com/privacy/peekmo Contact: help@cottonray.com
