Workout
Saved workout on this device
Pick a template, then start. Your active workout is saved on this device until you finish.
Edit template
Build the reusable template below. Add from your exercise library or create a new one, then drag bubbles to reorder.

Nutrition tracker
Cronometer-style diary
Log foods by meal and keep daily calories and macros visible against your targets.
Food diary
Today’s food
Copy a past day or meal
Reuse a previous day. Copies are added to the target — nothing is overwritten or deleted.
Saved meals
Save a logged meal as a reusable template, then add it to any day. Adding appends the saved items — nothing is overwritten, and editing a diary entry never changes a saved meal.
Recipes
Build a reusable recipe from your foods and set how much it makes, then log any number of portions. Logging saves a scaled snapshot — editing or archiving a recipe never changes entries you already logged.
Add food
Add food manually
Manual day totals fallback
Use yesterday-like totals as a starting point, then adjust before saving.
Body metrics
Log body
History
Recent logs
Quickly review what has already been logged.
Goals
Set the targets the dashboard and Hermes coaching should compare against.
Coaching profile
Tell Health OS what coaching should be based on. Saving this does not change goals or workout templates.
Edit coaching profile
Weekly recommendations
Whether the data you have already recorded would let Health OS propose a weekly change. It does not propose one yet, and nothing here alters your goals, templates, or logs.
Security
Change the temporary password after you have confirmed login works on your phone.
Add Exercise
Add food
Favorites and foods recently used for this meal appear first. Choosing a food always opens amount, unit, meal, and date confirmation.
Review food
Enter nutrients per 100 g.
Repeat food
Logs this exact stored serving again — the amount and nutrients are copied unchanged. Choose where to add it, then Add.
