One Last Thing is a tiny nighttime doorway to Apple Reminders. When something is keeping your mind awake, write it or dictate it. Tap “Set it down” and the thought goes directly into the Reminders list you choose. The app keeps no private copy. Use Shortcuts with Wind Down, Bedtime, or Sleep Focus to start a quiet Live Activity on your Lock Screen and Dynamic Island. It stays ready for the stray thought that arrives after the lights go out—without showing the thought itself on your Lock Screen. Features: • Saves directly to an Apple Reminders list you select • Text and voice capture • Automatically follows your iPhone language, with an optional override • Live Activity for Lock Screen and Dynamic Island access • Shortcuts actions to start, end, or add a thought • Undo during the current nighttime session • True-black, low-light interface • No account, analytics, advertising, tracking, or cloud service • Seven-day free trial with no automatic charge • $0.99 one-time lifetime unlock; no subscription One last thing. Then sleep.
