Make your to-do list impossible to ignore. Persistent home and lock screen widgets keep what matters in sight, with notifications that match your urgency.
Don't ignore your to-do list anymore.
ListBox makes your Apple Reminders list impossible to ignore. A persistent home screen widget keeps your list always visible. Lock screen notifications stay present, keeping your list top of mind. Choose how insistent you want it to be — from a quiet glance to a full nag.
No new account. Apple Reminders stays your source of truth — your lists live in iCloud, where they always have. ListBox only stores what's needed to deliver notifications: your selected list contents and your preferences.
— PERSISTENT VISIBILITY —
The widget on your home screen shows your top items at every glance. The lock screen notification stays in Notification Center even after newer alerts arrive. Your list comes to you, not the other way around.
— FOUR MODES, FOUR LEVELS OF INSISTENCE —
Quiet — Ambient awareness. The widget updates; no notifications.
Nudge — A gentle ping every few hours during your active window.
Persistent — Steady reminders, every hour, keeping your list in front of you.
Nag — Frequent reminders for the things you absolutely cannot let slip.
Switch modes anytime. Set your active window so notifications respect your evenings.
— BUILT ON APPLE REMINDERS —
Pick any list from your Reminders. Add, edit, check off, and delete items in either app — they stay in sync via iCloud. Your data is yours, where it has always been.
— DESIGNED FOR FOCUS —
Adjustable display density (Comfort, Standard, Compact, Dense) lets you decide how much fits on your screen. Adaptive list colors match your selected Reminders list. Quiet, intentional design that disappears into the background until you need it.
— PRIVACY-FIRST —
No tracking, no analytics, no advertising. Ever. See our privacy policy for full details on what we store and why.
— REQUIREMENTS —
- iOS 18 or later
- Apple Reminders permission
- Notifications permission (optional, for non-Quiet modes)
