The science.
Every number in MyPotential comes from a fixed formula, run on your own logs. The targets follow public health guidance, from bodies like the World Health Organization. Here is each one, and why.
- No AI makes your score.Fixed formulas, run on your phone.
- You, compared with you.Recovery and patterns read your own history, never other people's.
- Nothing named before day 10.A week of data is mostly noise.
- Not a medical device.It never diagnoses anything.
What it knows, and when
It won't guess before it knows. Each step starts on the day your data can carry it.
Day1
A score for today
Once 2 pillars are logged. While the day is still open the score is capped, so an early number cannot flatter you.
Day2
Potential
From your first finished day. Today is never in it. Marked early until day 7.
Day3
Recovery, measured
With Apple Health, after 3 nights of heart data, compared only with your own nights. WHOOP and Oura send their own from the start.
Day10
The one thing, named
From your own data, across up to 28 days. Before this it only shows today's biggest drag, and says so.
Day12
Your link, tested
Once both pillars have 12 logged days, the Why page says whether your days match.
Day14
Your real burn
Your calorie target starts learning from your food and weigh-ins, at most 150 kcal a week.
Day28
The full window
Potential and the one thing now read 28 days. Older days count less, so a change shows fast.
Your score
Potential starts at 100. Each pillar takes points off for the gap between what you did and your target, weighted for your goal. It averages your last 28 days, and recent days count more.
How we calculate it
- A pillar's cost for a day is 100 × its weight × the credit you missed, divided by the total weight of the pillars you logged.
- Partial progress is squared: half your target earns a quarter of the credit.
- A pillar you did not log is left out, never counted as zero.
- A day 14 days old counts half as much. Today is never in it.
- Your quiz answers pick the weights. Change them any time in Settings, under Scoring, and past days are scored again.
| Pillar | Long game | Body | Feel sharp |

The one thing
For the first 10 days it only shows today's biggest drag, and says that is all it is. From day 10 it names the pillar costing you the most points across your last 28 days.
How we calculate it
- A pillar needs 3 days of its own data before it can be named.
- A new pillar has to cost 3 points more before the name changes, so it does not flicker.
- Watch history from before you installed counts, on days it measured at least 2 pillars.
- Meds is never named.
Why it holds you back
Some pillars reach others. Short sleep, for one, can make training feel harder. The app tests one such link per pillar on your own days, chosen before it looks at your data.
How we calculate it
- Say sleep is your drag. It removes your overall trend and your weekday habits, splits your days into short nights and normal ones, and compares training after each.
- Then it shuffles those labels 2,000 times, within the same week, to see how often chance does as well.
- It says your data agrees only when chance matches it 5% of the time or less. It needs at least 12 logged days of each pillar.
- Why one question and not a search: test enough pairs and something always looks linked by luck. So it commits to its question first.
- It never says one thing caused another.
Recovery and Strain
Recovery says how ready you are. Strain says how hard the day was. Neither one is part of your score.
How we calculate it
- With WHOOP or Oura: their own number, as is.
- With Apple Health: heart rate variability and resting heart rate during sleep, against your own last 60 nights. Never against other people.
- Measured after 3 nights, marked early until 14. Without a watch, an estimate from your sleep and how you feel, labelled as one.
- If your resting heart rate runs well above your normal, the reading is held low. It flags; it never diagnoses.
- Strain is WHOOP's own, or a 0 to 21 load from workout heart rate, sets lifted and everyday movement.
Pillar by pillar
Each target, and the reason for it.
Sleep
8 hplus what you owe
Short nights cost the next day: harder sessions and more food.
Sleep need follows the National Sleep Foundation and the American Academy of Sleep Medicine.
How we calculate it
- Your need is 8 hours, 9 under 18 and 7.5 from 65, plus up to 1.5 hours of debt from your last 3 nights.
- A night scores 50% on hours, 30% on regular timing, 20% on time asleep in bed.
- Short of your need, you lose 30% of the credit per hour.
Cardio
150 mina week, or 7,000 steps a day
The weekly amount the World Health Organization sets for adults.
How we calculate it
- Steady minutes count once and hard minutes count twice, over a rolling 7 days.
- Or your average steps, once there are 3 days of readings.
- You get the better of the two, never both added.
Training
3sessions a week, or your plan
Strength and cardio together do more than either one alone.
How we calculate it
- On a planned day, a logged session is full credit. Rest days never count against you.
- With no plan: 3 sessions a week, paced through the week.
Calories
0.5%of body weight a week, when losing
Slow enough to keep your strength.
Protein follows the International Society of Sports Nutrition.
How we calculate it
- Your burn starts from a standard equation for resting burn and how active you are.
- After 14 logged days it learns your real burn from your food and weigh-ins, moving at most 150 kcal a week.
- Losing aims at 0.5% of body weight a week, from 0.25% to 1% if you choose. Never under 1,200 kcal, and never under your resting burn.
- Protein: 1.6 g per kg, 2.0 when cutting.
- Under 18: no deficit, ever.
Hydration
Yoursfrom your body, not 8 glasses
Weighted low on purpose. It counts, just less than sleep or food.
Water and caffeine limits follow the European Food Safety Authority and the US FDA.
How we calculate it
- Built from body weight, sex, age and activity, then training, heat and caffeine on top. Between 1.5 and 6 litres.
- Alcohol never adds water, and never raises any score.
- Caffeine counts here too, against 400 mg a day, or 3 mg per kg under 18. The app also shows a last-cup time, 8 hours before bed.
Screen time
Your goalsocial and video apps
Late scrolling pushes bedtime back.
How we calculate it
- Social and video apps only. Full credit at or under your goal, nothing at double it.
- No goal set, no score. Screen Time data never goes to AI.
Spending
Your budgetlogging and pace
Measured against the budget you set.
How we calculate it
- Half for logging, half for pace against your budget from the 7th of the month.
- Rent, bills and subscriptions never count.
Goals
Your plandays on pace this week
Measured against the plan you made.
How we calculate it
- Days you hit the plan this week, against the pace it needs.
Meds
As prescribeddoses taken
Supplements are tracked, never scored.
How we calculate it
- Doses taken against doses due.
- Meds is never named as what holds you back.
Mind and Recovery
0weight in your score
How you feel feeds Recovery, not your score. Mind counts once you choose a practice.
What it never does
- Never says one thing caused another. Only whether your days line up.
- Never makes a number up. Luna only states numbers the formulas already made.
- Never under 1,200 kcal. And no calorie deficit under 18.
- Never scores faith. Faith is tracked for you, never judged.
- Alcohol never raises a score. Not water, not anything.
