Common Questions

Frequently asked questions

How accurate is the AI?
We tested against 3,490 lab-weighed meals from Google Research’s Nutrition5k dataset. Median calorie error: 62 calories per meal. On meals over 200 calories, error drops to 23–34%. These are approximations, not clinical measurements — you can edit any value if the AI estimate doesn’t look right. See the full benchmark results.
Does it work offline?
The USDA food search database (13,000+ foods) is stored locally and works without an internet connection. AI-powered features — photo analysis, voice logging, text analysis, barcode lookup, and the AI Coach — require an internet connection.
What does a subscription include?
A subscription includes AI meal analysis, AI nutrition coaching, progress tracking, and widget support. Plans: $12.99/month or $69.99/year. New annual subscribers can start with a 7-day free trial.
