Built by dad, inspired by daughter!


Leftover Life started the way a lot of good ideas do — with frustration.  


I'm a dad who got tired of throwing money in the trash every week. Wilted vegetables, mold on my berries, forgotten leftovers, expired yogurt that nobody touched. The waste added up fast, and no amount of good intentions seemed to fix it.  

So I built the app I wished existed.  

My daughter is the other half of TwoUnicorns LLC — the creative spark, the one who said just do it, dad, and the reason "less waste, more taste" became our motto. Building something meaningful together, for families like ours, is what Leftover Life is really about.


  We're not a big company. We're a dad-and-daughter team who believe that small habits — knowing what's in your fridge, using what you have, wasting a little less each week — add up to something worth building.  

We hope Leftover Life earns a spot in your kitchen.  — Duan & the TwoUnicorns team


40% of food in the US goes to waste

8% of global greenhouse emissions from food waste

Less waste, more taste—let’s reduce spoilage and save some groceries.

The average family throws away nearly $1,500 of food every year. That's not a grocery budget problem

Leftover Life was built to solve it. Scan a QR code on any container, log what's inside, and the app takes it from there — tracking expiration dates, organizing your fridge into smart zones, and nudging you before something goes bad.  


No more opening the fridge and finding week-old leftovers you forgot about. No more tossing the berries you swore you'd eat. 


No more mystery containers in the back that you're afraid to open.  Just a smarter fridge, a little less waste, and a few extra dollars that stay in your pocket every week.
