Calorie Camera
Accompany users to build good habits within 21 days

Background & Goal
This app is an AI-driven experimental project that explores new ways of building products using vibe coding, generative AI, and ChatGPT. Our goal was to launch the app on the App Store within four weeks from ideation to release.
Features & User
The app offers simple yet powerful calorie tracking features, including photo-based food logging, editable prompts, AI-generated reports (meal analysis and next-step suggestions), and meal history records. Its primary goal is to help users maintain a calorie deficit, with a particular focus on women. Since eating and recording habits differ between genders, we prioritized women first—especially as women show a stronger preference for app-based weight-loss services.
Impact
Validated a new workflow of building products with vibe coding and AI integration. Collaborated closely with engineers and PMs to ensure timely delivery, enabling the team to ship an AI-powered calorie tracking app in just four weeks with a strong user reception (4.4 stars on the App Store).
