NutriSwipe: Learn Calories & Macros by Playing

Inspiration

I’ve always been really into nutrition and how food affects performance, energy, and daily habits. But I noticed that most people (myself included) are surprisingly bad at estimating calories and macros in everyday foods. NutriSwipe was inspired by the idea of turning that gap in intuition into a fun, fast-paced learning game instead of something boring like charts or long articles.

What it does

NutriSwipe is a swipe-based educational game that helps users learn nutrition through interaction. Players are shown foods and first guess their calorie content. Then they enter a swipe challenge where they compare foods and decide which has more or less calories. The game repeats the process for macros (protein, fat, and carbs). At the end, users get a score, and if they perform well, they unlock an interesting fact about the original food.

How we built it

NutriSwipe was entirely built using MeDo. The game logic, UI flow, and scoring system were iteratively refined through conversation with the platform. We also structured the experience into distinct stages (calorie guessing → swipe comparisons → macro rounds → results screen) to keep gameplay smooth and engaging.

Challenges we ran into

One of the main challenges was designing a game that is both fun and educational without becoming too complex. Balancing difficulty was important. If it’s too hard, users disengage; if it’s too easy, it loses educational value. Another challenge was structuring the swipe comparison logic in a way that feels intuitive and fast-paced while still reinforcing learning.

Accomplishments that we're proud of

We’re proud that NutriSwipe transforms nutrition learning into something interactive rather than passive. The swipe mechanic makes it feel like a game instead of a quiz, and the multi-layered structure (calories + macros + comparisons) creates depth without overwhelming the user. The fact-based reward system also adds a nice sense of progression and discovery.

What I learned

It was my first time designing an educational app. I learned that small, repeated interactions (like swiping comparisons) are powerful for building intuition over time. I also learned how important pacing and feedback loops are in keeping users engaged.

What's next for NutriSwipe: Learn Calories & Macros by Playing

Next, we plan to expand the food database, add difficulty levels, and introduce streaks and leaderboards to increase replayability. We also want to add personalization features, such as focusing on specific diets (high-protein, vegan, weight loss goals). Eventually, NutriSwipe could evolve into a full nutrition awareness platform that helps users make better food decisions in real life.
