The average calorie database contains millions of food entries. Sounds helpful — until you're at a restaurant, hungry, and trying to figure out which of 47 "grilled chicken" entries is closest to what's on your plate.
The Database Problem
Traditional calorie apps are built around search. You type "pasta bolognese," get 300 results, pick one that seems right, estimate a portion in grams (which you can't actually see without a scale), and repeat for every ingredient.
This process takes 5–10 minutes per meal. Research shows that fewer than 20% of people who start using a calorie tracking app are still using it after 3 months. Friction kills habits.

Photo logging with Pacali takes under 10 seconds:
No searching. No scrolling. No weighing.

The Habit That Sticks
The best tracking method is the one you'll actually use consistently. A 90% accurate log you maintain for 3 months beats a 100% accurate log you abandon after 2 weeks.
Photo-first tracking removes the #1 barrier: time. That's why Pacali users log 4x more meals per week than users of traditional calorie apps.
