Nutrition tracking
Search a big food database or snap a photo. Sixteen tracks calories and macros against a goal you set, then shows what a late dinner did to your sleep stress the same night.

Your nutrition score is calories and protein against your goal, with the timing that your sleep can feel.

Set a weight goal and Sixteen suggests a calorie and protein target. Change it any time.
Meals are logged with time, so a heavy meal at 11pm sits next to the sleep stress it caused.
Calories, protein, carbs and fat as simple bars. A daily score so you know whether the day landed.
Then it changes the day
