Self-reliance, measured
Holdout turns what you keep — water, food, fuel, medicine, power, sanitation — into one number: roughly how long you could go without a store run. Not a survival plan. A way to see where you are thin, what will expire before you get to it, and what belongs on the next trip into town.

Who this is for
Any of these sound familiar to you?
Four people, a chest freezer, a well pump and a woodstove. Nobody here is preparing for the end of anything. They would rather not find out on a Sunday afternoon that the propane is low, or read about a recall on the ground beef after it was eaten. Holdout says what belongs in the truck before the next run into town.

Supplies Watch Restock
Long-term food in buckets with dates nobody wants to hold in their head, two chainsaws, a generator that gets run once a quarter, and a second place eighty miles out with its own shelf and its own number. Holdout stops counting a bucket on the date printed on the lid. And when the generator comes due it looks at the week: clear today, but a freeze is coming Thursday — worth doing before then.

Supplies Upkeep The plan on paper
Well water, propane, a solar array and a battery bank, and all the canned goods you put away this year. Holdout says when the battery bank is due for service and when the pantry needs restocking. It counts everything in the units it is actually stored in — gallons, pounds, cords, amp-hours — and names which of the six categories is holding the whole place back.

Supplies Upkeep Restock
An elderly parent in the back bedroom, a prescription list that runs on refills, and an oxygen concentrator that has to stay plugged in. The figure that matters in this house is not the pantry. It is how many days of medicine are in the cabinet, and whether the power holds until the next delivery. Holdout counts the prescriptions against the calendar and puts a refill on the list while there is still a trip that can fill it.

Supplies Restock Watch
Twelve head, a hay supply, a tractor with a service coming due, and a feed store that closes on Sunday. Feed and bedding are tracked on their own rather than folded into the household figure — the people in the house and the animals in the barn do not draw from the same shelf. And the feed run is not the grocery run. Holdout keeps them as separate trips, so diesel never turns up on a list for the supermarket.

What you get
Water, food, fuel, medicine, power and sanitation, kept in whatever unit you actually store them in — gallons, cases, pounds, cords. Add categories of your own for anything else. Expiry dates count, so a case that goes off soon does not pad the number.
Scan supplies in or out in batches with the camera staying open. Six cans of beans is six scans and one row reading six. A recognized barcode brings its package size with it, so a 907 gram bag is recorded as two pounds of food and not as one bag of something.
Generators, pumps, vehicles, filters, chainsaws. What makes a job due is the calendar, so nothing goes quiet because a mileage reading never got written down. And the reminder reads the week before it suggests a day — clear today, but a freeze is coming Thursday.
Warnings checked against where your places actually are, so a county-wide alert that does not reach you stays out of the way. Recalls, quakes and space weather sit alongside them, folded so one event is one entry.
The question is not what is lowest today. It is what will not last until you can next buy it. Holdout works out how much to get and which run to put it on, because the grocery trip and the feed run are not the same list.
One sheet for when there is no phone to look at. Every place you keep things, what is held there, how long each would last on its own, and the bearing and distance between them.
Kept close
What you keep, where you keep it and everything you write down about it are encrypted before they are stored, and every household has its own key. Nothing is sold, nothing goes to advertisers, and nothing about your household is shared to make this app work for anybody else.
The little that has to leave the server goes out to answer a question you asked, and the privacy policy sets out exactly what, and when.
