About On The Lock - Lock Screen Memo
On The Lock is a simple memo app that keeps one important thing visible on your Lock Screen.
On The Lock helps you keep quick notes, todos, photos, and today’s context where you actually notice them: the Lock Screen.
Write a memo the moment it comes to mind, turn it into today’s todos, and keep your next step visible with Live Activity. Use Home Screen and Lock Screen widgets for quick capture and check-off. Add photos for visual context, connect Calendar for today’s remaining events, set a target date/D-day, and customize layouts, colors, text size, alignment, and background skins.
Organize with categories, reminders, completed items, archives, iCloud backup, and an option to hide sensitive content while your device is locked.

Latest updates
2.10.4
• Sticky notes on your wallpaper: in the wallpaper maker, stick as many sticky notes as you like and pick a color (yellow, pink, mint, blue) and tape for each.
• A truer sticky-note skin: the Lock Screen "Sticky Note" skin now looks like a sheet of paper held by tape.
• New stickers, Memochi: 8 cute Memochi stickers, free.
• Completed list: checked to-dos leave the list right away, with an instant undo. See them by day in Completed, and bring them back or delete them. Completed to-dos are removed automatically after 30 days.
• Morning nudge: if you like, we'll ask every morning what you must not forget today. It pauses after 7 days without use.
• Show to-dos on the Lock Screen: one button on the to-do page puts your to-dos on the Lock Screen.
• Also: the "about to pause" reminder is gone. Converting a memo you already turned into to-dos now tells you so, and checking a to-do no longer makes the list jump.

2.9.0
• 내 할 일이 그려진 잠금화면 배경: 배경화면 위에 메모·할 일·D-Day·스티커를 원하는 곳에 놓고, 단축어로 잠금화면에 바로 적용해요. 정해진 시각마다 자동으로 새로 그리기는 On the Lock+에서 쓸 수 있어요.
• 할 일 미리 적어 두기: ‘보일 날짜’를 정하면 그날 0시에 오늘 할 일과 잠금화면에 나타나요.
• 할 일도 앱 안 열고 바로 추가: 제어 센터·액션 버튼·Siri로 할 일을 바로 넣어요.
• 더 풍부해진 꾸미기: 카드 배경 진하기, 맑은 유리 카드, 손글씨 글꼴, 귀여운 스티커 24종이 생겼어요.
• 잠금 중 내용은 마스킹테이프로: 꾸민 카드는 그대로 두고 글자만 가려요. 탭하면 20초 동안 보여요.
• iPhone ↔ iPad 옮기기: 다른 기기의 백업을 알려 주고 버튼 하나로 가져와요.
