Calorie Camera App

AI analysis in every shot for smarter eating

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. 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).

Overview

Problem

One of problems we found in the modern calories tracker app is that they normally require users to

  • manually input the names of foods they consume (across multiple categories)

  • rely on calorie data entered by other users which may be inaccurate due to individual differences in portion size

Urban users tend to abandon tracking because logging is slow, repetitive, and cognitively exhausting.

Drop-off caused by effort, not lack of intent

👉 an opportunity for AI intervention

Solution

Target User: Urban female professionals pursuing fat loss via diet control.

Design Process

Design Challenge 1

How can users tell how much they can eat at a glance?

How much you can eat, how much is left, and what counts as “over.”

Proposal A

✅ Clearly shows remaining calories for the day
❌ Does not communicate today’s calorie deficit

Proposal B

✅ Creates a sense of urgency through a declining water-level animation, which feels calming and engaging
❌ Does not clearly communicate today’s calorie deficit

Final Decision: Proposal G

Status Card and Status Bar with emoji

4 eating stages

This solution enables users to take action at a glance while clearly communicating flexibility around eating goals—an advantage not offered by competing products.

Design Challenge 2

How can AI features enhance human control through explanation, transparency, and user-editable interactions? (HCAI)

Design Iteration: editing food items from the meal process

Users can edit contents and know how AI calculate this meal easily.

Conclusion

Effortless calorie tracking, powered by human-centered AI

Calorie Camera demonstrates how thoughtful design and AI integration can transform a traditionally tedious task — calorie tracking — into an effortless, user-centric experience. By identifying core pain points in existing solutions (manual entry, high interaction cost, and inaccurate data), we crafted an MVP that empowers users to log meals with a single photo while maintaining transparency, control, and flexibility in their decision-making. In just four weeks, the project validated a rapid, AI-augmented workflow and shipped an AI-powered product that achieved positive early user reception and supported personalized nutritional insights. This case underscores how combining human-centered design principles with generative AI can significantly reduce friction, meet real user needs, and open new avenues for data-driven personalization in health tech.
