How to keep a pantry inventory (without it becoming a chore)

Most kitchen inventories die in the second week. It isn’t the setup that kills them: an evening with a notebook is enough for that. It’s the upkeep. Every shop, every meal and every half-used jar is something to update, and the day you skip it, the list stops being true. A list you can’t trust is a list you stop opening.

So this guide is less about making an inventory and more about keeping one alive. The trick is to track less, and to update at the moments you’re already handling food anyway.

1. Decide what question it should answer

An inventory is only useful if it answers something you actually ask. For most kitchens, that’s one of two things:

• “What needs using first?” Getting to food before it goes off.
• “Do I already have this?” Not buying a third jar of cumin.

Pick the one that matters more to you. It decides what goes on the list.

2. Don’t track everything

This is the rule that makes the rest possible. Salt, spices, oil and baking soda last for months and are easy to see. Tracking them adds work and tells you nothing.

Track the things that are perishable, easy to lose, or easy to double-buy:

• Fridge: meat, fish, dairy, open jars and sauces, leftovers, soft fruit and veg.
• Freezer: everything. The freezer is where food is best at hiding.
• Pantry: the things you buy on autopilot (tins, pasta, rice, cereal) and anything opened.

If a pack is sealed and lasts a year, it can wait.

3. One list per place

Sort by where things live, because that’s where you’ll look: fridge, freezer, pantry. For each item, write down four things:

Item	Amount	Date	Date type
Chicken breast	400 g	14 Oct	Use by
Spinach	1 bag	15 Oct	Use by
Chopped tomatoes	2 tins	Mar 2027	Best before
Frozen peas	¾ bag	Frozen 2 Sep	—

The last column is worth the extra second. A use-by date is a safety line, and best before is about quality. They call for different decisions (see use by vs best before). For frozen food, write the date you froze it.

4. Sort by date, not by when you bought it

A list in shopping order hides the one thing you need to see. Sort each place soonest first, so the top of the list is always “what needs me”.

Do the same on the shelf: new things go to the back, older things come forward. It’s called first in, first out, and it’s how every restaurant kitchen works. It turns the inventory and the fridge into the same picture.

5. Update when food changes hands, not on Sundays

A weekly “stock-take” is exactly the kind of admin that gets skipped. Update at the two moments you’re already dealing with food:

• When shopping comes in. Your receipt is already a list of what you bought, so add the perishables straight from it while the bags are still on the counter.
• When something runs out. Cross it off. If it’s something you always buy, it goes straight onto the shopping list.

That’s it. Cooking a meal doesn’t need an update unless it finishes something.

6. The five-minute weekly look

Once a week, read the top of each list, the soonest dates, and ask one question: what am I cooking with these? Two or three items that need using usually make one dinner on their own. Plan that meal first, then shop for the gaps.

This is the step that actually saves food, and it only works because steps 2–5 kept the list short and true.

7. Pick a tool you’ll still use in a month

Any format works if you keep it up. Honestly:

• Paper on the fridge door. Always visible, zero setup. But it doesn’t sort itself, and it doesn’t come shopping with you.
• A notes app. Always in your pocket. Sorting by date is manual.
• A spreadsheet. Sorts by date, and it’s free. Nobody updates a spreadsheet with wet hands.
• An inventory app. Does the sorting and reminding for you. Only worth it if adding food is faster than writing it down, otherwise you’re back to the week-two problem.

Where Nudgey fits

Nudgey is built around the upkeep problem, because that’s where inventories fail:

• You don’t type your shopping in. Photograph the receipt and Nudgey pulls the items off it for you to check. By default the reading happens on your phone and works offline. On iPhone you can turn on smart scan for sharper reading: the photo is sent to be read and isn’t kept.
• Everything is sorted by what needs you first, across fridge, freezer and pantry.
• You get a nudge before something is due, at most one a day.
• Recipes are ranked against what you actually have, starting with what needs using. That’s step 6, done for you.
• Ticking off your shopping puts it back in the inventory, with places and dates already guessed.

Your inventory stays on your phone: no account, no cloud.

Nudgey is coming soon to iPhone, with Android following. It starts with a 7-day free trial, then it’s a subscription.
