A shelf of buckets isn't an answer. Days of Supply counts what you actually have — food, water, fuel, medication — against what your household actually uses, and tells you which one runs out first.
7 days free. Cancel any time. Your list stays yours — export it whenever you like.
Most preparedness advice counts calories and stops. But a year of wheat is worth very little if you run out of the fuel to cook it in a fortnight. This works out every resource separately, then reports the one that fails first.
This household would last about 1 day — not 249. Fuel is the weak link, and a pantry photo would never have shown it.
Stored fuel goes off, and not at the same rate. Treated gasoline is good for about a year, mixed two-cycle for a couple of months, kerosene for years. Propane cylinders need requalifying twelve years from the stamp on the collar, after which a filling station can legally turn you away.
Food and water get the attention. Medication is what actually runs out first in a long disruption, and it's the one thing you can't improvise. Enter what's on hand and how many doses a day, and you get days per person — with critical prescriptions warned earlier, because a 90-day fill needs planning and a prescriber's approval.
A rusted can you can see. An expired passport you can't. Licences, permits, insurance policies and identity documents each carry their own renewal lead time, because a hunting licence takes a week and a passport can take two months.
Everything else in storage is a finite pile that only goes down. Game is the exception. Ammunition and tackle are counted alongside the part people forget — a way to keep the meat, which decides whether a deer is five days of food or fifty pounds of waste.
So point your phone at the label. It reads the product, the date, the calories and the category, and files it — including the pack dates and "best if used within three years" wording on a case of storage food.
Set the goal and the app works backwards to what's missing, in the units you'd buy it in.
The long-term staples counted the way they're normally taught — grains, legumes, milk, fat, sugar and salt, per person, with what's still short expressed in buckets and cases rather than pounds.
The FEMA baseline: a gallon of water per person per day and food that needs no cooking, checked against what a shelter-in-place order would actually demand of your house.
Typing items in by hand is unlimited on every plan, including the free one. Nobody gets locked out of their own inventory.
Count what you have and see where you stand.
The whole picture, shared with your family.
For a cabin, a second home, or parents you keep stocked.
No. Start with one room. The number updates as you go, and a partial count still tells you which resource is weakest — which is usually the useful part.
Because days of supply is arithmetic about one building. A week of food at home tells you nothing about the cabin, so each property keeps its own inventory and its own number.
Nothing is deleted. You keep your inventory and you can export the whole thing to a spreadsheet at any time. You lose the paid features, not your data.
Your account is yours alone, and the only people who can see it are the ones you invite into your household. Sign-in is a link sent to your email — there's no password for anyone to steal.
It's built for one. Add it to your home screen and it runs like an app, including offline in the storage room where the signal drops.
Most households are surprised — usually not by the food, but by the thing sitting next to it that runs out in a day.
