When Did I…

Gentle reminders for the occasional things that matter.

When did you last change the filter, water the plants, rotate the tires, or test the smoke detectors? When Did I… gives you a calm place to remember—without turning your life into a task list.

Remember with one tap

Record something as done and keep a clear history of every date. Correct a date anytime if you logged it late.

Set your own rhythm

Add an optional day, week, month, or year interval. Gentle reminders bring an item back when the time feels right, and “Not now” lets you defer it without creating a false completion.

Stay in sync

Your items work offline and can stay current across your iPhone and iPad with iCloud. Home Screen widgets keep what matters close at hand.

Simple, private, and portable

No separate account is required. Export all your items and recorded dates to CSV whenever you like.
