LumenAI
An AI food tracker for iPhone: point your camera at a meal, hit your goals, keep your streak.
Challenge
Most nutrition apps feel like spreadsheets, or like a coach with a guilt trip. We wanted logging a meal to take seconds, not willpower.
Approach
Photograph your plate and Google’s Gemini AI estimates what’s on it. Or scan a barcode against the open Open Food Facts database, or just search. Each meal becomes calories, macros and micronutrients against targets set for you.
Result
LumenAI is in public beta on TestFlight. It keeps a daily logging streak, flags micronutrients you’re trending low on, projects your weight toward a goal you set, and never stores your meal photos.
