LyteFast is a weight tracking app with AI-powered food scanning, weight forecasting with Auto-Zoom charts, carbon footprint tracking, gluten detection, and budget-based calorie management.
How does the weight forecast work?
LyteFast uses your recent weight data, calorie intake, and activity to project your near-term weight trend. The Auto-Zoom chart focuses on the most relevant slice of your journey and shows when you'll reach milestones.
What are the daily usage limits?
To keep LyteFast fast and affordable: AI Food Scanning has a 50 calls/day limit, Barcode Scanning has 100 calls/day, and Text-based Food Analysis has 100 calls/day.
How does carbon footprint tracking work?
Each meal scan includes estimated CO₂e (carbon emissions) so you can see the environmental impact of your food choices over days and weeks.
How does gluten detection work?
LyteFast displays gluten status indicators based on barcode scanning and meal analysis, helping you make informed choices for celiac disease or gluten sensitivity.
What is budget-based calorie tracking?
Instead of just counting calories, LyteFast treats calories like a budget - showing 'spend vs. budget' so you always know if you're on track, near your limit, or over budget.
How accurate is the AI food scanner?
The AI Food Scanner provides calorie estimates based on image recognition. Results are estimates and work best with clear photos. For packaged foods, use the barcode scanner for verified nutrition data.
What languages is LyteFast available in?
LyteFast is available in 40 languages, including English, Spanish, French, German, Japanese, Korean, Arabic, Hebrew, and many more - including Luxembourgish, making it the first fitness mobile app available in that language!
How much does LyteFast cost?
LyteFast offers a 3-day free trial. After that: $0.99/week, $2.99/month, or $23.99/year (best value). Cancel anytime in your device settings.
