The one thing you can't forget right now โ€” keep it on your Lock Screen. Your todos, memos, and schedule stay visible without opening the app. Notifications disappear once they pass, and memo apps only show things when you open them. Cue is different. Pick one thing, put it on your Lock Screen, and it quietly stays there until you're done. [Live] Put a todo or memo on your Lock Screen with a single tap. It's right there every time you wake your screen. It doesn't vanish like a notification. [Calendar] Check today's schedule right on your Lock Screen. The monthly calendar shows your whole month at a glance. [Focus Mode] Pick one thing to focus on and start the timer. While the timer runs, what you need to do stays right in front of you. [Timeline] The Cues you put up today stack up in time order. You can also schedule a Cue to appear again at a specific time. [Sync] Automatic iCloud backup. No sign-up needed. Your data lives only on your device and in iCloud โ€” no external servers. Cue is for you if: You jot things down in a memo app and never open it again, Your to-do list stays just a list, You want to focus on one thing now โ€” not the whole plan. Not an app for managing your day, but an app that keeps showing you the one thing you can't forget right now. Cue your day.
