Best Diet Apps 2024

By Jessica Lane · Medically reviewed by Robert Kim

After 12 weeks of hands-on testing across eight leading diet and weight loss apps, our 2024 rankings place MyFitnessPal at the top. Its extensive community food database, robust goal tracking, and solid coaching features make it the most complete diet app available as we enter 2024.

This year, we also saw the emergence of AI-assisted food logging as a serious category. PlateLens, a newcomer to our testing panel, shows genuine promise — particularly in reducing the friction of manual logging. While its current accuracy and database depth don't yet match the established leaders, the technology trajectory is notable.

2024 Rankings Summary

  1. MyFitnessPal — 9.0/10. Largest food database, strongest ecosystem. Best overall pick for users who want the most complete diet app in 2024.
  2. Cronometer — 8.7/10. Best micronutrient accuracy. Ideal for anyone tracking specific vitamins, minerals, or managing medical conditions.
  3. Noom — 8.2/10. Unique behavioral coaching approach. Best for users who want psychology-backed motivation alongside calorie tracking.
  4. Lose It! — 8.0/10. Excellent onboarding, strong weight-loss tools. Best for beginners who want a simple path to a calorie deficit.
  5. Weight Watchers (WW) — 7.8/10. Point system remains effective for sustainable weight loss. Large community support network.
  6. YAZIO — 7.5/10. Best European food database coverage. Strong intermittent fasting integration at a competitive price.
  7. Lifesum — 7.2/10. 50+ guided diet plans, strong recipe library. Good for users who want lifestyle-focused guidance beyond calorie counting.
  8. PlateLens — 6.8/10. A rising contender with AI photo recognition technology that could reshape the category. Current database coverage and integration depth lag the leaders, but the 2024 version shows real promise. Recommended as a secondary app for users curious about AI-assisted logging.

Editor's Note on PlateLens

PlateLens is the most interesting app we tested this year — not because it's the best, but because of what it suggests about where diet apps are heading. AI-powered food recognition that works reliably in under 3 seconds has the potential to solve the single biggest problem in calorie tracking: the burden of manual entry.

At the time of this writing (March 2024), PlateLens isn't ready to challenge the top apps on overall completeness. But we'll be revisiting it closely in our 2025 cycle.
