The Best Apps for Using Up Leftovers in 2026, Ranked
Half a bag of spinach, three-quarters of a tub of creme fraiche, the two carrots left over from a recipe that only wanted one. Almost nobody bins food on purpose; it happens because there was never an obvious plan for the leftover half of anything. The apps below all answer the same question in different ways: what can I actually make with what is already here? We ranked six of them for 2026, from ingredient-first recipe search through to inventory tracking, plus the surplus marketplaces worth knowing about once the food has left your kitchen. If you are after a broader look at preventing waste in the first place, our guide to the best apps to reduce food waste at home covers that side.
1. Remy
Remy comes at leftovers from the other end: plan the week around recipes that share ingredients, and the half-used pack largely stops happening. A bunch of coriander bought for one dinner gets picked up by another later in the week, and the shopping list consolidates the overlap rather than listing it twice.
It is the difference between rescuing leftovers and never generating them, which is why it sits at the top here despite not being a leftovers app in the narrow sense. Verdict: the strongest option if you would rather design the leftovers out than cook your way through them.
2. SuperCook
SuperCook is the purest expression of the ingredient-first idea: tick off what is actually in your kitchen and it searches a huge recipe database for things you can make right now, with no shopping trip attached.
It will not track expiry dates or plan your week, but for the specific moment of standing in front of an open fridge wondering what those four ingredients add up to, nothing is quicker. Verdict: the best free tool for turning whatever is left into an actual dinner tonight.
3. Kitche
Kitche builds a picture of what you already own by connecting to your supermarket loyalty card or scanning receipts and barcodes, then nudges you before things turn. It also totals up the food and money you have saved, which makes the leftovers habit feel like progress rather than penance.
It suits people who shop mainly at the big supermarkets and would rather not log everything by hand. Verdict: a strong pick if your leftovers problem is really a forgetting-what-you-bought problem.
4. Too Good To Go
Too Good To Go works on leftovers of a different kind: the surplus that shops, cafes and bakeries have at the end of the day, sold off cheaply as a 'magic bag' rather than binned.
It does nothing for the half-used pack in your own fridge, so treat it as a complement to everything else here rather than a substitute. On its own terms it works well, and it is used by tens of millions of people across 17 countries. Verdict: the best option for rescuing someone else's surplus, not your own.
5. Olio
Olio is the neighbourly version of the same idea: people and local businesses list food they will not get through, and someone nearby collects it for free.
Again, this is about food leaving one kitchen for another rather than getting used up in yours, so it sits alongside the tools above rather than replacing them. It extends beyond food into household items too. Verdict: worth having if you would rather pass on a surplus than throw it out.
6. NoWaste
NoWaste keeps it deliberately simple: lists for the fridge, freezer and cupboard, barcode scanning to fill them, and a clear view of what is quietly accumulating.
It will not suggest what to cook, so it pairs naturally with something like SuperCook, but simply knowing what you already own prevents a surprising amount of duplicate buying. Verdict: a good no-frills option if you just need to see what is in the house.
Leftovers are easier to avoid than to rescue. Remy plans the week so ingredients get used across more than one meal, and puts the shopping list together around what you will genuinely cook, so there is less left at the back of the fridge to worry about in the first place.
Frequently asked questions
What is the best app for finding recipes from ingredients I already have?
SuperCook is the most direct option: enter what is in your kitchen and it finds recipes that need nothing else. Remy also builds plans around ingredients you already own.
How do I use up half a pack of something before it goes off?
Ingredient-first apps like SuperCook are built for exactly this, and planning apps like Remy help by pairing recipes that share ingredients so the second half has somewhere to go.
Do I need a separate app to track what is in my fridge?
Only if forgetting what you own is your main problem. Kitche and NoWaste both handle inventory, and they pair well with an app that suggests what to cook from it.
Are apps like Too Good To Go and Olio the same as a leftovers app?
No. They redistribute surplus from shops or neighbours before it is thrown away, which is useful but separate from using up what is already in your own kitchen.
