Frequently asked questions
Which AI nutrition tracker offers the most accurate calorie counts?
MyFitnessPal maintains the largest verified food database with 14+ million entries and community moderation, making it statistically the most accurate for common foods. Cronometer prioritises scientific accuracy for micronutrient data. Both undergo continuous peer verification, though restaurant items and processed foods sometimes vary by 5-10 percent depending on exact product variants.
Can these apps recognise foods from photos using AI?
Yes, MyFitnessPal, YAZIO, Lose It!, FatSecret, and Nutritio all feature AI photo recognition (sometimes called computer vision) to identify meals and automatically populate nutritional data. Recognition accuracy typically exceeds 85 percent for common whole foods and prepared meals, though complex dishes or unclear images may require manual verification.
What is the real cost difference between free and premium versions?
Most apps offer free basic tracking with optional premium subscriptions (£3.99-£9.99 monthly). Premium typically unlocks advanced AI features like personalised meal planning (YAZIO, Lose It!), detailed micronutrient analysis, recipe suggestions, and ad removal. Nutritionix Track and FatSecret remain fully free with no premium tier, making them suitable for budget-conscious users.
