People at the supermarket. Woman checking her cell phone. The app tells her what food she has left at home.

What's Left: the app that scans your supermarket receipts to calculate what's left in your kitchen.

It's saturday morning. it's obvious: the fridge is empty. Your kids are asking you if there's any peanut butter left. Your partner is looking for marmelade and you don't have any coffee left. The good thing is that you have noticed that some stuff is missing. Do you know what you should put on your shopping list? Are you so organized that you have an inventory of your available food? Are you tracking your kitchen ingredients? Most likely not. Do you go through all your closets and your fridge before going shopping? Or do you rather follow your intuition? What if someone could tell you in a few seconds what's left and in which quantity? What's Left does exactly that! The app gives you a prognosis of all the food left in your house, based on your supermarlet receipts. The more receipts you scan in the app, the more precise What's Left will be.

Food inventory prognosis

What's Left - prognosis of what food is left at home.

What makes What's Left so unique is its prognosis feature. It tells you what food you have left at home. What's Left bases its prognosis on all the receipts you have scanned in the app. As soon as you have enough scanned receipts (2 to 3), a pourcentage bar will show in your What's Left items. Moreover, an estimation of the quantity left will be calculated and shown.

What's Left is born

What's Left was born in the swabian Jura in Germany during the first Corona weeks in spring 2020. What's Left's creator took up the challenge to digitalize his kitchen and to update it autmatically. One summer without a pool nor vacation in southern France and hundreds of hours of work later, the challenge is mastered. Or at least the basic idea!

What's Left's Mission

Let's face it: grocery shopping is rather a chore than anything pleasant. Hence, we want to help you shop in a more comfortable and efficient way so you can save time for things that matter to you. What's Left enables you to digitalize, to control and to evaluate all your supermarket purchases. Even better: What's Left gives you a prognosis of what's left at home. Then, you always have an overview of what you may need anytime anywhere.
