Pip
A shared cookbook that writes the shopping list.
My partner and I meal prep every weekend, and for a long time the grocery list lived in Apple Notes. Its multiplayer syncing sucked. I got tired of it, so we built Pip — an app for how we actually shop and cook together.
You save recipes to a shared cookbook — paste a URL and it scrapes and parses the recipe for you. Pick what you’re cooking this week and the ingredients land on a shared shopping list, scaled to your servings and grouped by aisle. Both phones stay in sync, so whoever is at the store sees the real list.
Under the hood: React Native with Expo, NativeWind, and Clerk for accounts. An Express backend on Railway does the recipe parsing with OpenAI’s help; the data lives in PostgreSQL through Prisma.
Pip is live and in daily use, and the whole loop holds up — save, plan, shop, cook. If you meal prep with someone, give it a try.
