Cut your food waste in half. Save up to €1000/year per person.

Track your impact with every meal you cook.

OH, a potato! is an app for food waste designed for real households. It helps you cut food waste by adapting to how you actually cook, eat, and plan, not how some ideal version of you might behave.

We believe food waste has become too easy, a silent, habitual act that’s disconnected from the true cost it carries. Our vision is to reframe household food choices as everyday opportunities for climate action, not through guilt or perfectionism, but with a smart, quiet tool that supports real life. Every home is different, and most digital solutions ignore that. That’s why we build an adaptive system that learns from each household’s routines, preferences, and habits, using behavioural design to help millions reduce waste effortlessly, save money, and feel empowered about their impact.

With Potato you can

Cut waste without overthinking it

Scan your fridge or grocery receipt to log what you have. Get alerts before food spoils, plus recipe ideas tailored to what’s about to expire. Missing something? Potato suggests smart swaps. Too tired to cook? Get rescue prompts to freeze, pickle, or stash ingredients for later. Sharing the load? One plan, one grocery list, all recipes, synced across your household. This app for food waste is designed to work with your habits, not against them.

See your impact, every time you cook

Track how much money and CO₂ you’ve saved this month, this year, or all-time. This app for food waste even projects your future savings based on how you currently cook and plan. You’ll see milestones that actually mean something: “€52 and 41 kg CO₂? That’s the chef’s knife you’ve been eyeing.” Real milestones. Real motivation. And you’re not doing it alone. Every cooked meal contributes to a growing, global food-saving mission.

The more you cook, the smarter your Potato gets

If you've ever said these things...

I buy a jar of tahini or a bag of spinach, use a bit, and don't know what to do with the rest.
I want to make a plan. But not feel trapped by it.
I can't commit to what I'll want to eat next Thursday.
I planned it. Bought it. Now I don't want it.
I want variety but not a 50-item grocery list.
Saved 47 TikTok recipes. Cooked none.
I hate waste but also don't want lentil soup 5 days in a row.
I ask my partner what to eat. They say 'pizza' or 'I dunno.'
I want to try new recipes but not on a Tuesday night.

This isn't for everyone. (But it might be for You.)

You want to cook more, waste less, and stop feeling bad about groceries gone rogue. You like a bit of weird with your utility. You want results, not rules. Then yeah. It's for you.
