Nutralyze — AI food swaps that explain why (what to eat instead, instantly)
Hi! I built Nutralyze, a mobile app that suggests healthier or more suitable alternatives the moment you type the food (and amount) you want to skip — e.g., “150g fries” → get swaps with a quick rationale.
How it works
Enter the food + amount you’d like to avoid.
AI returns contextual alternatives (similar taste/texture, better macro balance, cooking method).
A “Why this suggestion?” screen explains the logic (calories/protein, cooking method, diet fit).
Don’t like a result? Block it so it won’t appear again.
Diet filters (beta): vegan, vegetarian, keto, etc., to tailor suggestions.
What I’ve learned so far
Users don’t just want swaps — they want the reasoning behind them.
Adding amounts (g/ml) makes results noticeably more accurate.
A personal block list is key for long-term relevance.
Short demo videos (TikTok/Reels) help people “get it” fast.
Looking for feedback
Is the first-run hint “Type food + amount” clear enough?
On the “Why” screen, which signals help most: macro/kalorie info or taste/texture + cooking?
For diet selection, would you prefer chips or a dropdown?
Managing blocked items: simple list or categories/tags?
Tech: Expo + React Native; multi-step prompting with a structured output format.If you’d like to try it and share thoughts (especially on the “Why” explanations and onboarding), I can DM a App Store link. Honest critiques are super welcome — thanks! 🙏
