Bling makes food tracking more visual by turning a meal photo into an estimated calorie and macronutrient entry, then adding a sticker to a daily scrapbook. Users can review and adjust the suggested food and portion before saving. Goals for calories, water, and macros are set from a short setup and can be edited later. The app also tracks water, weight trends, and nutrition history, with optional Apple Health syncing for height and weight. Streaks, achievement badges, widgets, Live Activities, and Dynamic Island display help keep the diary close at hand. A subscription is required for full access, though the listing does not state prices or billing periods. Photo-based nutrition values are estimates and should be checked against the user's actual meal.
