2. Ease of Use: Speed of logging, interface clarity, and learning curve for new users.
3. Feature Depth vs. Simplicity: Breadth of nutrient tracking balanced with usability.
4. Integration Ecosystem: Compatibility with wearables, fitness trackers, and health platforms.

6. Support & Community: Access to education, coaching, and user support.
7. Specialized Diet Compatibility: Inclusion of options for keto, vegan, fasting, or other dietary patterns.

Each app was used for at least two weeks under realistic daily conditions to evaluate long-term consistency and data reliability.
