Overview
The home hero is three equal rings: Calories, Condition, and Mission. They are three different kinds of fact deliberately given the same visual weight: energy recorded, body context observed, and actions completed.
Underneath the calorie ring sit your daily targets: one calorie target and three macronutrient targets. This page covers where those numbers come from and what each ring is actually measuring.
How it’s calculated
The Calories ring
The calorie ring fills with the energy from your recorded meals against your calorie target for that date. Macronutrient progress (protein, carbohydrate, and fat) is shown alongside it.
Your targets come from date-effective revisions, not from one mutable current value. Every confirmed change commits a revision that becomes effective on the local date you approved or saved it. Reading any past date resolves the latest revision effective on or before that date, so today’s change never rewrites what yesterday was measured against.
When Grio derives macro targets from a calorie target, it uses published anchors:
| Macro | Rule |
|---|---|
| Protein | 1.8 g per kg of body weight, for every goal |
| Fat | 30% of calories, dropping to 25% when the goal is weight gain |
| Carbohydrate | The remaining energy after protein and fat |
The protein anchor sits inside the range recommended for exercising adults, and the fat share sits inside the adult acceptable macronutrient distribution range. The gain case shifts the surplus toward carbohydrate rather than fat, so extra energy arrives as training fuel. All three are yours to override.
The Condition ring
The Condition ring shows the day’s Condition Score. It is body context, not an achievement; you do not “complete” it. See how the Condition Score is calculated.
The Mission ring
The Mission ring is the mean completion ratio of the day’s countable
occurrences. Its centre shows the completed count over the countable total
(1/3), or a dash when the day has nothing countable.
Two rules govern it:
- A completed occurrence always fills its whole slice, including a numeric mission finished by a single tap. Partial numeric progress moves the arc alone and never inflates the completed count.
- Allowances are excluded: an
at_mostmission, such as “coffee at most two”, measures how much of a limit the day used, and it settles only when the local date closes. Including an open limit would either hold the ring down all day or make a completion count shrink in the evening.
Edge cases and fallbacks
- A same-day target change re-evaluates the current occurrence. Day close freezes the resolved target.
- Nothing recorded yet: an empty ring, not a zero score.
- Pre-rollout target history is not inferred or backfilled, so Grio makes no claim about revisions from before its first canonical one.
How to read your score
- A full calorie ring is not the goal on its own: Read it next to Food Quality, which measures what those calories were made of.
- A partial Mission ring at 4pm is normal: the day is not over.
- A dash is not a zero: it means there was nothing countable to measure, or nothing observed yet.
The frequent misreading is treating three full rings as a perfect day. They measure energy, observed body context, and completed actions: three useful facts, none of which is a verdict on the day.
What to do with it
- Set the calorie target once and change it deliberately: every change writes a dated revision, which is what keeps your history readable.
- Adjust protein first if you are editing macros: it is the anchor the other two are derived around.
- Keep the countable mission list short: Three occurrences means each is worth a third of the ring; twelve means each is worth almost nothing, and the ring stops telling you anything.
Troubleshooting & FAQs
- I completed a mission with one tap. Why did the ring not fill fully?
- It fills its whole slice of the arc. The ring is full when, and only when, every countable occurrence of the day is done, so one completed mission out of three fills one third. The centre shows the same thing as a count, such as 1/3.
- My "at most two coffees" mission is not moving the ring. Is it broken?
- No, allowances are excluded from the completion ring by design. That ring counts actions accomplished, and including an open limit would either hold the ring down all day or make it shrink later in the evening. An allowance settles only when the local date closes.
- I changed my calorie target today. Did yesterday change too?
- No. A target revision becomes effective on the local date you saved it, and earlier dates keep the target that was in force when you lived them. That is what stops a change today from rewriting what yesterday was measured against.
