Days of Supply
How long would you really last? Photograph a label and this works out your days of food, water and fuel.
How long would this last?
Worked out from who's in your household and what's actually on the shelf. Water is usually the surprise.
If the power went out
Pick how long and this works out where you'd run short. A ticked box tells you that you own a generator; this tells you whether you can actually run it until the lights come back.
These drive the fuel maths. The generator defaults are typical for a mid-size portable unit — check the plate on yours if you want it exact. The gas questions matter because piped gas usually keeps flowing in a power cut, but most gas appliances still need electricity to run.
Add an item
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.
Send a label photo to Claude in your chat conversation, then paste the code block it gives you back here. Tell Claude how many you have and it'll include a "quantity" in the block.
By category
Storage targets
Household
Who you're packing for. Ages pick the right starting list, and the app flags a kit when someone grows into a different one.
72-Hour Kits
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.
Vehicle Kits
What lives in each vehicle. Different list from a go-bag — this one is about getting the car moving again, or staying warm in it. One kit per vehicle, and the seasonal add-ons swap out twice a year.
Home Readiness
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.
Two things to get right before you need them.
Run a generator outdoors only, at least 20 feet from any door, window or vent, and never in a garage even with the door open — carbon monoxide kills people every winter, and it gives no warning. Keep a working CO detector on each sleeping floor.
For light, use battery or LED lanterns rather than candles; open flame during an outage is a leading cause of house fires. If you do burn candles, use a wide-based holder on a hard surface and never leave one in a room you've left.
Inventory
Good = more than 6 months out · Use soon = within 6 months or no confirmed date margin · Expired = past estimated date · Needs a date = no readable date on the label, so add one and this can track it.
Shopping list
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.
Reminders
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.
Medicine & first aid
Food and water get the attention, but medication is what actually runs out first in a long disruption. Enter what's on hand and how many doses a day, and this works out the days per person.
The way to build a buffer is a longer fill, not smaller doses.
Ask your pharmacy about a 90-day supply or mail order, and ask your prescriber about an emergency supply — many states allow emergency refills during a declared disaster. Never stretch a prescription to make it last; for anything like insulin, heart medication or an anticonvulsant that's more dangerous than the shortage.
This app only counts what you enter. It doesn't advise on doses or on how much to keep — that's between you and your prescriber.
Hunting & fishing
Everything else here is a finite pile that only goes down. This is the one thing that adds days back. Ammunition, tackle and — the part people forget — a way to keep the meat.
Licences & documents
A rusty can you can see. An expired passport you can't. Each document carries its own renewal warning, because a hunting licence takes a week and a passport can take two months.
