A calorie tracker for students has to be free and fast on food that has no barcode: cafeteria trays, shared shawarma, and 11pm delivery. Photograph the tray. Log the drink. Save the two takeout places you actually repeat. A Premium scanner for campus groceries is the wrong product.
Khatwa is free on iOS and Android. Photo logging, a coach that uses leftover calories, and a home program for the weeks the campus gym is a rumor. That is the stack that survives exams.
Free has to mean you can finish the day
Photograph the tray in Khatwa. Ask what is left. No logging cap for "just this week."

Log it like restaurant food. Oil and bread still count. Protein still decides whether you are wrecked at 4pm. For a floor on grams, use protein per day.
