Getting Started
Quick setup with progressive onboarding
- Progressive Onboarding (2-5 minutes)→Scan a few pantry items to start—build momentum without doing everything on day one
- Quick Start Guide→Get started in minutes with basic meal and receipt tracking
- Your First Meal→Calibration workflow: Weigh your first meal type 3 times to learn your portion sizes (~90 seconds total, then single-tap forever)
- Understanding Pricing→£19.99/month base + £9.99/month per additional member—simple per-person pricing
Meal Logging
3 weigh-ins per meal type, then single-tap forever
- Meal Logging Best Practices→How to calibrate your portion sizes in 1-2 weeks, then never weigh that meal again
- Single-Tap Meal Logging→How 90% of meals become 1-second taps from predicted top 5 list
- Gaussian Portion Models→How 3 weigh-ins create statistical models for fast logging + reconciliation corrects to ground truth
Features
Advanced tools for effortless nutrition tracking
- Setup Pantry→One-time pantry scan (20-30 min) that enables physics-based reconciliation for 93% weekly accuracy
- Quick Log→One-tap meal logging with AI predictions—log meals in 1 second after calibration (Week 3+)
- Staples Management→Periodic rescanning of long-lasting items (60 sec/week) to maintain accuracy
- Tracking Dashboard→Monitor daily nutrition, view meal history, track macros and micronutrients, and see trends over time
- Pantry→Track your food inventory across fridge, freezer, and pantry with expiry alerts and waste logging
- Meal Planner→Personalized meal suggestions based on your pantry and preferences
- Household Management→Invite members, merge accounts, split households—manage your family nutrition tracking
Receipt & Barcode Processing
15-second scan with 2M+ barcodes + Mistral AI
- Receipt OCR Technology→Scan receipts—Mistral AI auto-maps items in 15 seconds across 2M+ preloaded barcodes
- Network Effects: Receipt Database→First user maps item → Saved for all users forever → Month 12: 95%+ cache hit rate
- Intelligent Caching (2M+ Barcodes)→2M+ barcodes preloaded + fuzzy trie matching → Week 1: ~100% manual → Week 8: 100% auto-matched
Reconciliation Engine
Mass conservation physics for research-grade accuracy
- Mass Conservation Physics→How physics achieves ~93% accuracy: consumed = purchased - remaining - waste (ground truth)
- Expiry-Based Auto-Reconciliation→3-tier system: Fast-expiring (auto), slow-expiring (conditional), ultra-stable (rare reweigh)
- Recipe Learning via Reconciliation→How mass conservation learns your recipes: grandmother's sambar (8.5g oil/100ml, not generic 3g)

Technical Architecture
Calibration → Single-Tap Logging
- • Week 1-2: Weigh 3 portions per meal type → Gaussian calibration
- • Week 3+: 90% single-tap (1 sec), 9% search (10 sec), 1% weigh (30 sec)
- • Weighted average: 2 seconds per meal
- • Weekly effort: 2 minutes (vs 2+ hours for competitors — Harvey et al. 2019, Obesity)
Data Infrastructure
- • Backend: Java Spring Boot + PostgreSQL
- • Hosting: Railway (EU) for GDPR compliance
- • Storage: AWS S3 (EU) with 30-day retention
Mass Conservation Reconciliation
- • Physics equation: Consumed = Purchased - Remaining - Waste
- • Fast-expiring: Milk expires → Auto-reconcile all meals
- • Slow-expiring: Rice consumed? → Prompt reweigh
- • Result: 93% accuracy ground truth (corrects Gaussian estimates)
Intelligent Caching (2M+ Barcodes)
- • 2M+ barcodes preloaded: Instant nutrition lookup for most products
- • Fuzzy trie: OCR-aware edit distance (handles "Teseo" → "Tesco")
- • Mistral AI: First user scans → Maps for all users forever
- • Network effects: Month 12: 95%+ cache hit → 15 sec receipt scan
