Is Free AI Coaching Accurate Enough?
For the core question most people care about — is the calorie and nutrient tracking accurate on the free tier? — the answer for PlateLens is yes. The AI photo recognition technology is the same on free and paid plans. The accuracy difference (±1.2% in both cases) does not change with the subscription tier.
What changes with premium is the depth of the AI coaching layer: free users get basic responses, while premium users get fully adaptive coaching that learns their patterns, accesses their full meal history, and provides the 82+ micronutrient analysis that defines PlateLens's clinical-grade capabilities.
