Each year, approximately1.3 billion tonsof food is wasted globally. This isn’t just a waste of valuable resources like water, energy, and labor—it also means that a significant amount of money is thrown away. You might think that the hospitality industry is the main contributor to this problem, but the reality is different. Around40% of global food wastecomes from households, making them the biggest offenders. The good news? Reducing food waste at home is actually easier than you might think and can have a huge impact on both your wallet and the planet.
This highlights just how important it is to tackle food waste on a personal level, and with simple actions, each of us can make a difference!
A good purchase needs to be well planned, regardless of whether you are a consumer shopper (which is what we are in our household, for example) or a stock shopper. The shopping list is essential. You can write it down on an old-fashioned piece of paper or digitally on your smartphone. There is now an app for almost everything. Before you go shopping, you should think about what your menu might look like for the week (for us, that's every day or every two days). Then you should check what you have left in the house. Incidentally, the shopping list always helps me to only buy what we really need, which in turn has a positive effect on my wallet.
How often has this happened to me? I've gone shopping with a growling stomach and suddenly, for some inexplicable reason, the shopping cart was full to the brim. Since then, I've gotten into the habit of eating at least a snack before I go shopping.
The best-before date simply indicates the date until which the manufacturer guarantees that their product is still edible - provided it is unopened and stored correctly. Once the best-before date has been reached, this does not mean that you have to dispose of the product immediately. Rely on your sense of taste and smell. If the food still tastes good and smells appetizing, then it is very likely that it is still edible. I know people who have even eaten yogurt that had been expired for over a year - and they survived. However, I am careful with meat and fish that is past its best-before date.
Personally, I can't stand it when I have to throw food away. We recently had a case at home with eggs that were a few days past their best-before date. So we spontaneously decided to make spaghetti carbonara. One egg didn't pass the “egg test” and had to be thrown away, but we were able to use the rest without any problems. So if you have food in your fridge/storage cupboard at home that has reached its best-before date, why not see what you can conjure up from it? I find that one-pot dishes are perfect for using up food that is about to expire. If it gets too much, you can simply invite friends over and eat the portions together.
To prevent food from being bought pointlessly and then thrown away, you should plan at least roughly what you are going to eat throughout the week. For example, Monday spaghetti, Tuesday schnitzel with chips and vegetables and so on. Planning your week can help you to go shopping in a targeted way. For example, I'm currently testing out a cooking box, which I'll blog about later. If you have the opportunity, you can also go shopping in an unpackaged store and get the exact amount of food you need. This is also good for the environment as it saves on packaging waste.
Keep track of supplies, groceries and durable products before small price increases turn into unnecessary extra costs.
Or try it right in your browser — no install neededFood can of course also be preserved by freezing, preserving, canning or dehydrating it.
The shelf life of food naturally also depends on how it is stored. What belongs in the fridge should of course be stored in the fridge (logical, right?) and dry food should be stored in such a way that it cannot absorb moisture or is protected from pests.
If you want to fight food waste, our Smantry.app can be a very helpful tool. With the help of our app, you can get a targeted overview of what food you still have at home. After shopping, simply scan the barcode and assign the right storage location to the food in question. As the cherry on the cake, you can also record the best-before date for the respective food in our app. Our Smantry.app also allows you to keep track of what food you still have in the house and how much of each product - so it no longer disappears into the depths of the freezer or store cupboard.
The recent Berlin power outage reminded many people: emergency preparedness isn't prepper folklore but everyday common sense. Germany's civil protection office recommends households keep a ten-day stock. Sounds like a lot – it isn't, if you approach it right.
Important: the numbers are guidance, not dogma. A stock made of things you genuinely like gets maintained – one made of dusty specialty cans gets forgotten.
The smartest emergency stock is a "living stock": buy a little more of what you use anyway, always eat the oldest first, and restock. Nothing expires and nothing costs extra. Our guide which foods to stockpile shows what works best.
A checklist on the fridge is outdated from day one. In Smantry you instead define minimum stock levels for your emergency items: the app shows how many days you are covered, warns about expiring items and automatically puts missing things on the shopping list. The preparation statistics give you the full picture.
You don't have to buy a 10-day stock this weekend. Add three extra items to your next shop, record them in the app, and repeat for a few weeks. Preparedness is a subscription, not a sprint.
The internet is full of before-and-after photos of perfectly sorted pantries. What you don't see: what they look like eight weeks later. Order that lasts isn't created on one big cleaning Saturday but by a system that works with your routine – three building blocks of 5 minutes each.
Not the whole pantry – just one zone. This week the pasta shelf, next week the cans. Expired items out, opened items to the front, quickly update the stock in the app. After a few weeks everything has been covered once, without it ever feeling like a project. The idea behind it is explained in our article on the 5S method.
The use-it-up zone is the game changer: it turns "there's something in the back somewhere" into a visible cooking assignment. Our leftover recipes supply the ideas.
New to the back, old to the front – sounds trivial, but fails without an overview of expiry dates. That's where digital tracking helps: Smantry sorts your items by best-before date and reminds you in time. Our guide shows how to model storage locations, shelves and compartments in the app.
Organizing systems fail at the entry barrier, not at willpower. Three small weekly habits beat any mega cleaning day – because they happen on the side, before chaos even builds up. Start with a single zone. Today.
In August, gardens and markets overflow – and in January a tomato costs three times as much again. Canning closes exactly that gap. You don't need grandma's canning machine or a cellar shelf: a big pot, clean jars and one afternoon are enough to get started.
1. Sterilise jars and lids in boiling water for 10 minutes. 2. Fill hot, prepared food (tomato sauce, chutney, compote) to 1–2 cm below the rim. 3. Wipe the rims clean and close firmly. 4. Place the jars in a water bath and process for 30–90 minutes at 90–100 °C depending on the recipe. 5. Let them cool – the lid must curve inwards. If it doesn't, refrigerate and use up soon.
Pickled and sugar-rich preserves usually keep 6–12 months stored cool and dark. What matters most is checking: inspect the lid, look, smell – and when in doubt, throw it out.
Home-canned jars have no barcode – with Smantry you can print your own barcodes and record every jar with its use-by date. The app reminds you before the winter stew quietly expires on the shelf. Our article on storing autumn treasures shows the best storage spots.
Since version 1.39, two updates have been released, and together they shift the app’s focus. Until now, it was mainly about recording and keeping track of individual items. From now on, it’s about your inventory as a whole: With the new inventory mode, you can update an entire stockroom in just a few minutes, minimum stock levels tell you what’s missing rather than just what’s there, and the interface has been redesigned in the places you tap most often.
The most common reason why inventory in an app eventually becomes inaccurate is simple: over time, a gap develops between what is listed and what is actually on the shelf. Until now, your only option was to correct items one by one. Now there is a dedicated mode for that.
The inventory mode doesn't start with your entire stock, but with the question of where you are right now. You select a storage location—“pantry,” “freezer,” or “cellar”—and Smantry shows you only the items stored there. The on-screen prompt says it plainly: _“Start taking inventory right in front of the storage location.”_ That's exactly how it's meant to work—phone in hand, cupboard door open.
The counting flow itself is deliberately kept simple so that it runs quickly:
Two details that make the difference between a counting aid and an honest supply:
Which unit do you mean? If a product with multiple expiration dates is stored in the storage location, Smantry does not guess. When you remove a unit, it asks: _“Which unit are you removing?”_—and indicates which one you should use first. When you add one, it instead asks for the new unit’s date, which you can either copy from the existing stock or enter manually.
Why is it being removed? When you reduce a quantity, Smantry asks why: _“Did you use it up, or did you have to throw it away?”_ This ensures that anything removed during an inventory count is included in your waste figures—instead of being hidden in a silent adjustment entry.
An inventory count is only worthwhile if it ultimately leads to action. That’s why the process doesn’t end with “saved,” but with a summary: how many items you checked at this storage location, how many stock levels were adjusted, and how many items were removed—broken down into used up and discarded.
And then comes the part that saves you work: Smantry lists everything that has fallen below your minimum stock level during inventory directly underneath—with a button labeled "Add to shopping list". From the shelf to the shopping list, with no extra steps.
For this to work, Smantry needs to know what counts as “enough.” You define that in the minimum stock levels—not laboriously for each individual item, but by category: two kilos of flour, six liters of milk, ten packs of pasta. The screen continuously shows you how many categories are active and what is still needed to reach the minimum levels.
New in the inventory list is the handy filter: “below minimum stock”. With a single tap, it turns the inventory list into a list of missing items—the view you actually want before going shopping. (A frequently requested suggestion from the feedback portal)
And if you're starting from scratch, you don't have to come up with the numbers yourself: Use "Load template" to import a ready-made set of minimum stock levels. The quantities are then scaled to the number of people and the desired period—you say "3 people, 10 days," and Smantry does the math.
The most important of these templates is the emergency supplies table from the German Federal Office of Civil Protection and Disaster Assistance (BBK). It is now available as a template in Smantry, using the published table as its source—so it contains the quantities actually listed there, rather than estimates. The source is identified in the template dialog, and a preview shows you what will be imported before you apply it.
This is accompanied by a small but important correction to the preparedness indicator: An item can now be marked as "Do not count toward emergency supplies"—intended for anything that may be on the shelf but won't keep anyone fed in an emergency. Wine and sweets are listed as examples directly in the setting description. This simply makes the statement "Prepared for 12 days" more accurate.
At the same time, we’ve refined the interface in the areas where most of the action happens. Not as a redesign for redesign’s sake—the list of changes may sound unremarkable, and that’s exactly the point:
The cleanup list introduced in version 1.39 has gained the step it was missing. When you remove an item from it, Smantry no longer asks why in a text dialog, but instead displays two illustrated cards: used up or thrown away. You can grasp the difference in half a second instead of having to read it.
The fact that the loading spinner appears on the card you tapped may sound like a minor detail—but it makes the difference between “I know what’s happening” and “I’ll tap again.”
We’ve made adjustments to the new durability screen introduced in 1.39 based on the feedback we received:
Sign-in now takes place on a dedicated, secure sign-in page (`identity.smantry.com`) – and best of all, it opens with a single tap and already knows whether you wanted to sign in or register. Cases that previously resulted in two accounts being created because an email address was already linked to a different sign-in method now prompt you for confirmation instead of displaying an error.
By the way: New accounts are now set up in your language. Previously, welcome content and emails could appear in English without warning, even though the app was running in German.
A large part of the work in these two versions is invisible in a private household, because it is meant for businesses: households can now belong to a company, with roles, seat-based billing and a log of every stock change. In the app you only see what concerns you — the note “This account is managed by your company”, for instance — and the option to issue material to people and take it back, right on the phone.
If you use Smantry professionally, write to us and we will show you.
Smantry 1.42 is available on the App Store and on Google Play. One tap on “Update” is all it takes — then give the new inventory mode ten minutes. One storage location is enough to see the point.
Do you have feedback on the new features, or an idea for the next version? Tell us directly in the app via the support chat or in the feedback portal. The “below minimum stock” filter, the one-tap calendar and the month-only mode all started there.
