When did I last?

Use case

When did I last replace my toothbrush head?

A toothbrush head has no wear you notice day to day, so the only way to know its age is to have written the date down. One tap when you change it is the whole job.

What goes on the list

Replace the toothbrush head

Every 3 months · Personal

Book a dentist appointment

Every 6 months · Personal

These come from the app’s starter packs, so the intervals shown are the ones it offers. They are starting points, not advice — change any of them when you add it.

How it works for this

Add one item per person in the house and the answers stay separate — the Ask tab will find "when did I last replace Ada’s toothbrush head" from the item’s own name.

The reminder arrives at the time you pick on the day the interval is up, and opens straight to the item so you can mark it done from the notification.
