When did I last?

Use case

When did I last change the smoke alarm battery?

Testing an alarm and changing its battery are two different jobs on two different clocks, and both are the kind of thing you only think about when you hear a chirp. Tracked separately, each one has a date you can actually look up.

What goes on the list

Test the smoke alarm

Every 6 months · Home

Replace the smoke alarm battery

Every year · Home

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

The app records the date you tell it, and works out the next one from the interval on the item. The intervals in the starter pack are starting points and you can change them to whatever your alarms, or the instructions that came with them, call for.

If you have several alarms, add one item per alarm and give each the name of its room. The Ask tab then answers "when did I last test the landing alarm" with that item and its dates.
