See Your Nutrition Progress

Tracking without the diary

Manual food logging fails the same way for everyone: search a database, pick from thirty near-identical entries, guess the portion, repeat every meal, quit by Friday.

Tuna's nutrition picture builds itself from what's already happening in the app. Cook a recipe, and its per-serving nutrition (calculated from the actual ingredients you used) lands on your day. Eat something from the pantry, and the label data follows. Eat out, and a one-sentence description gets you an estimate. You live your week; the dashboard keeps the ledger.

The daily picture

Open the dashboard and today is at a glance: calories so far, protein, carbs, and fat, tracked against your targets. Planned meals count as estimates until you confirm them; confirmed meals count as fact. You always know how much room dinner has.

The default view is deliberately simple: calories and the three macros. If you watch specific nutrients, guardrails go deeper.

Goals and guardrails

Everyone in a household gets their own targets:

• Calories: your daily energy target, derived from your own numbers and adjustable anytime
• Macros: protein, carbs, and fat targets, computed from your weight and goal, customizable
• Guardrails: per-nutrient ranges for whatever you personally watch, like sodium, fiber, or saturated fat

Goals are personal even when the kitchen is shared. Your partner's cut and your bulk can coexist over the same pot of chili, because portions land on each person's day against each person's targets.

Trends over days

A single day doesn't tell you much; the pattern does. The dashboard tracks your last seven days against your goals, so you can see the shape of the week:

• Solid weekdays and a 600-calorie weekend drift.
• Protein that consistently sags at lunch.
• The one meal time where a guardrail keeps getting bumped.

The point isn't a verdict, it's information you can actually act on next week.

Honest numbers, labeled honestly

Not all nutrition data is equally solid, and Tuna doesn't pretend otherwise:

• Label data from scanned products is exact
• Recipe data is calculated from the actual ingredients you cooked with, very close to exact
• Estimates for described meals and restaurant nights are approximations, and they stay labeled as estimates everywhere they appear

Most trackers present every number with equal authority. Tuna keeps facts and estimates distinguishable, so when you look at the week you know which parts are measured and which are honest guesses.

No score, no shame

There are no streaks, badges, or perfect-week trophies. Skip a day of logging and nothing breaks; the dashboard just shows what it knows.

The goal is a true picture of how you eat, built with as little typing as possible, so the picture is still being drawn in March when every food diary has long since been abandoned.
