When did you last do it? When: Then & Next helps you remember the dates that are easy to forget — when you last changed the water filter, when your passport expires, when your next dentist visit is due, or when an important birthday is coming up. Everything is organized around two simple views: TIMELINE See what's coming next. Upcoming tasks, expirations and important occasions appear together in one clear timeline. LAST TIME See how long it's been since you last did something — whether that's getting a haircut, servicing the air conditioner, cleaning your camera sensor or changing a password. TRACK IT YOUR WAY Repeat Track things you do more than once. Simply remember when you last did something, or add a schedule if you want to know when it's due again.
