The AI Photo Snap is the fastest way to log food. It uses GPT-4o Vision — the same AI model that powers ChatGPT — to identify every food item in your photo.

How it works:

1. Tap 📸 Snap Food in the Today tab
2. Select a photo or take one with your camera
3. AI analyzes in under 3 seconds
4. Review the detected foods and quantities
5. Edit any item (tap to change portion size)
6. Tap Add All to log everything at once

Accuracy: GPT-4o Vision achieves ~90%+ accuracy on common meals. Always review and adjust portions for packaged foods — use barcode scan instead for packaged items.

Example commands:

The Meal Planner generates a full 7-day × 4-slot grid using the Smart Rotation Algorithm — a 100-point scoring system that ensures variety while matching your health profile.

Smart Rotation scores each recipe on:

• Recency (40 pts) — Avoid repeating meals you had in the past 3 weeks
• Cuisine diversity (25 pts) — No Italian 5 nights in a row
• Protein variety (25 pts) — Alternate chicken, fish, legumes, beef
• Favorites bonus (5 pts) — Slight preference for your rated recipes
• Gene-diet bonus (±15 pts) — Boosts recipes that match your gene/biomarker rules

Sync to Calendar: Tap the → Calendar button to push all meals as hyCalendar events. Each meal appears with its macros in your calendar.

The Gene Diet panel (in the Goals tab) reads your hyHealth profile and GeneOS DNA results to generate personalized dietary rules. It updates automatically as your health data changes.

What it uses:

• Gene variants — MTHFR, APOE4, FTO, VDR, COMT, TCF7L2, BCMO1 and more
• Biomarkers — Vitamin D, ferritin, B12, testosterone, cortisol, cholesterol, glucose, CRP
• Conditions — Hashimoto’s, PCOS, celiac, IBD, hypertension, diabetes
• Medications — 12 drug classes with food interaction rules

Tap Generate Gene-Optimized Week Plan to create a meal plan that prioritizes foods supporting your specific genetic profile.
