A macro tracker that turns food logs into useful targets

Macros are protein, carbohydrates, and fat. Each contributes energy, but each also has a different role in your diet. Protein supports muscle retention and growth, carbohydrates are a major training fuel, and dietary fat supports normal body functions.

Calorie intake still matters for weight change, so a useful tracker shows both the macro split and the total energy behind it. Caltra keeps those numbers in the same daily view and includes micronutrient detail when you want to look deeper.

Consistency matters more than using the most elaborate entry method every time. Search works well for staple foods, a barcode scan is fast for packaged products, saved meals handle routines, and custom recipes are useful for food you cook often.

AI photo logging is best used as a fast starting estimate. Check the detected foods and portions before saving when accuracy matters. Caltra gives you several logging routes so one awkward meal does not break the habit.

A static calorie calculator estimates where to start. Your real intake and weight trend show what happens next. Caltra combines those signals to estimate energy expenditure and can update calorie and macro targets each week.

That makes the log useful beyond record keeping. If your trend is moving differently than planned, the next target can respond instead of asking you to guess at a new number.

Choose a cut, maintenance, or gain goal. Log as completely as you reasonably can, record weight under similar conditions, and let the weight trend separate the signal from normal daily noise. Review the weekly recommendation before changing course.

No tracker can correct for meals that were only partly logged. If a day is incomplete, treat its numbers cautiously. A consistent, honest log is more useful than a perfect-looking one.
