Gastromancy
An AI kitchen assistant: photograph your fridge and get a real recipe — shaped by your mood, diet and allergies, and read aloud while you cook.
What’s in the fridge becomes what’s for dinner.
Problem
Recipe apps start from recipes. People start from whatever is left in the fridge — and from their diet, allergies and energy level that evening.
Approach
A React Native app built on Gemini 2.5 Flash with structured JSON output. Vision recognises ingredients from a photo of the fridge or counter; mood modes — lazy day, chef, student budget — change the style of the recipe; a saved diet and allergy profile is enforced in every request; and a hands-free voice mode reads each step aloud. Recipe cards can be saved to the photo library.
Result
A complete app with subscriptions and a published privacy policy in three languages, being prepared for the App Store.
