Pros & cons

Welling pros

  • Best-in-class AI food logging (photo, voice, or text in seconds)
  • Personalized program adapts weekly based on your data
  • Actually addresses the *behavior* behind overeating, not just numbers
  • Works alongside GLP-1s or independently
  • Strong privacy posture; no ad-based data sharing

Welling cons

  • Newer than MyFitnessPal so social/community is smaller
  • Premium needed for full coaching depth

Yazio pros

  • Affordable annual pricing
  • Good fasting timer integration

Yazio cons

  • Database leans European; some US foods missing
  • AI logging is basic

Our verdict

Winner: Welling. Welling is the only calorie tracker we tested that treats logging as a means to an end. The AI logging is the fastest we measured (≈4 seconds per meal), and the coaching layer is what kept testers logging at day 90 – when most apps lose 70%+ of users.
