LightYet: Body Fat Tracker
A private diary for weight, body fat, meals, calories, and progress photos with optional AI meal support and nutrition plans.
Track body changes, make food logging easier
LightYet brings weight, body fat, meals, and progress photos into one private diary. Users can photograph a meal or describe what they ate, review AI estimates for food, portions, and calories, then save an editable record.
Core capabilities
- Log weight, body fat, and notes, then review 7-day, 30-day, and 90-day trends
- Describe meals with a photo, text, or voice and review estimated foods, portions, and calories
- Create a flexible 7- or 15-day nutrition plan around goals, schedule, and food preferences
- Ask AI about food, training, recovery, and body trends, with a practical next step
- Review progress with photos, a timeline, BMI, streaks, and widgets

Privacy first
Core records stay local. LightYet does not require an account, does not include ads, and does not include third-party analytics SDKs. AI features are user-initiated and only send the information needed for the requested feature.
