## Why this exists
I'm a student trying to hit 140g protein daily without protein powder and on a budget. I got tired of checking every product at the store, so I built this for myself. Now it's free for everyone.
## Features
- **Smart scoring** — Products ranked by protein-per-price, taste, and calorie efficiency
- **Daily tracker** — Set your protein goal and log what you eat throughout the day
- **Works with any store** — Comes with sample data from Swiss stores, but add products from anywhere
- **Import/Export** — Share your product lists with friends or back them up as JSON
- **Mobile-first** — Designed for checking prices while you're at the store
- **100% local** — No account needed, all data saved in your browser
- **Open source** — MIT licensed, fork it, modify it, make it yours
## Quick start
```bash
git clone https://github.com/peaktwilight/protein.git
cd protein
npm install
npm run dev
```
## How scoring works
Each product gets a score based on:
| Factor | Weight | Why |
|--------|--------|-----|
| Protein per price | High | More protein per dollar = better value |
| Taste rating | Medium | No point eating something you hate |
| Calories per 100g | Negative | Penalizes calorie-dense options |
**Formula:** `(protein/price * 10) + (taste * 3) - (calories_per_100g * 0.1)`
## Sample data
The app comes with 28 pre-loaded products from Swiss supermarkets (Migros, Coop, Lidl, Aldi). You can start with this data or begin fresh with your own products.
