How do I create a reminder?
Tap the + button at the bottom-right of the home screen, fill in the title, date, time and time zone, then tap ✓ to save.

What's the difference between the due time zone and the display time zone?
The due time zone belongs to the reminder itself (e.g. Washington for a colleague abroad). The display time zone is what you want to compare against in the list (change it in Settings › Display Time Zone, or follow the system). When they differ, the time line on each card rotates automatically to show both.

How do I complete or delete a reminder?
Swipe right on a card to complete it, swipe left to delete. After deleting, an Undo button appears so you can restore it immediately. Swipe right on a completed card to mark it active again.

How do I export all reminders?
Go to Settings › Export Reminders. All active and overdue reminders are compiled into text sorted by due time, ready to share or paste into Notes.

Where is my data stored?
All data is stored locally on your device only and is never uploaded to any server. Deleting the app removes all data — use the export feature to back up.
