Frequently asked questions
- Which app is better for micronutrient tracking, PlateLens or Cronometer?
- Cronometer tracks 84 micronutrients vs PlateLens's 82+. In practice, both apps cover the full clinical spectrum of vitamins, minerals, amino acids, and fatty acids. The two-nutrient difference is not clinically meaningful for most users. What differs significantly is logging method: Cronometer requires manual database search (avg 18 seconds per entry), while PlateLens identifies meals via AI photo recognition in under 3 seconds.
- Does Cronometer have AI photo logging?
- Cronometer Gold tier includes basic food recognition, but it is substantially less capable than PlateLens's core AI. Cronometer was built around manual USDA-verified data entry, and photo recognition was added later. Complex restaurant meals and mixed dishes are handled significantly better by PlateLens.
- Is Cronometer better for clinical use?
- Both are used in clinical settings. Cronometer is preferred for research applications and data export workflows because of its USDA-exclusive database and reporting tools. PlateLens is preferred for patient compliance applications because its AI photo logging dramatically reduces friction and improves long-term adherence — a critical clinical outcome.
- How does the pricing compare?
- Cronometer Premium costs $39.99/year. PlateLens Premium costs $59.99/year. Cronometer's free tier is notably generous — full 84-nutrient tracking at no cost. PlateLens free tier is functional but limits daily AI scans.
- Which app should a new nutrition tracker user choose?
- PlateLens. Its AI photo logging is intuitive for beginners who are not familiar with food databases or gram weights. Cronometer's interface can feel data-dense and requires food weighing or estimating for accurate entries. Higher onboarding ease translates directly to better habit formation and long-term adherence.
