Worked out from who's in your household and what's actually on the shelf. Water is usually the surprise.

One photo is usually enough — get the front label with the date stamp in frame if you can. If it can't find a date, just type it in on the next screen. Turn off auto-read when you want to add a second close-up before analyzing.

Who you're packing for. Ages pick the right starting list, and the app flags a kit when someone grows into a different one.

What each person and animal carries out the door. Measured against a target list, so it tells you what's missing as well as what's expiring — and flags a kit when a child grows into a different one.

The shelter-in-place side: generator, fuel, heat, light, sanitation, tools. These don't get outgrown, they get neglected — so gasoline, bleach, batteries and the generator itself carry a service interval rather than a printed date.

Built from what's below its minimum, what's missing from kits, what's due for rotation, and what's about to expire. Tick things off in the store — it works with no signal — then press Add what I bought and the ledger updates itself.

An email digest of what's expiring, what's due for rotation, and what's missing from your kits. This is the part that works while you're not thinking about it.

Paper copies for the closet door, the clipboard, and the glovebox — the app is no help when the power's out.
