Health Grade gives you a live letter grade from A+ to F that updates through the day as you log food and move, so you always know where you stand before the day is over.
What Health Grade measures
Health Grade scores your day across five contributor categories. Each contributor reflects a constraint that matters for your goal.
| Contributor | What it reflects |
|---|---|
| Calories pacing | How close intake is to your daily calorie target |
| Macros quality | Protein, carb, and fat adherence to plan targets |
| Micronutrient coverage | Fiber and essential micronutrient intake relative to recommendations |
| Limits | Whether sugar, sodium, caffeine, and saturated fat stay in range |
| Movement | Active energy from Apple Watch relative to your baseline |
Calories pacing and macros quality together carry the most weight because they drive plan outcomes. Movement is the largest single contributor when Apple Watch data is available. Micronutrient coverage and limits act as quality modifiers that reward balanced eating and penalize excess. Each contributor ramps its influence based on how much usable data is available, so the grade stays fair on days when some data is missing.
How the grade updates
Health Grade is not a midnight verdict. It recalculates as new data arrives.
After logging a meal, the grade reflects the new intake. After a workout syncs from Apple Watch, the grade reflects updated energy context. By the end of the day, the grade has settled into a fair summary of what happened.
Coaching notes update alongside the grade. Each note explains why the grade landed where it did and what the most impactful next action would be.
Health Grade in Daily Review
Daily Review now opens with the Health Grade as its hero. The grade anchors the review so you can see the outcome before reading the breakdown.
Lighter-activity days are scored more fairly — a compliant fat-loss day on a rest day is not punished like a failure. The coaching message adapts to your preferred coach style, so the tone matches how you want Fuel to guide you.

Health Grade in Weekly Review
Weekly Review shows the grade with a day-by-day trend line and color shifts that make mixed weeks easier to read. You can see which days pulled the week up and which days dragged it down.

Health Grade widget
The Health Grade widget shows your current grade on your Home Screen so you can check in without opening the app.
See Nutrition Widgets for widget setup and limits.
Improving your grade
The fastest path to a better grade is fixing the contributor that scored lowest. If the grade is low because of calories, the action is portion control or an extra meal. If it is low because of movement, the action is a walk or workout. If limits are dragging the score down, reducing sugar or sodium is the highest-leverage change.
Coaching notes surface the specific contributor, so you do not have to guess.
Plan limits
Health Grade is available on both Fuel Free and Fuel Pro. Coaching notes that accompany the grade may be limited on Free.
