sleep, meals, training — one honest number.

manifesto

to track is not to know.

data without meaning is just noise.

clarity is the shortest distance between a body and a decision.

the rest is silence.

the sate score

recovery, nutrition, activity, stress, habits. resolved into one number.

a single instrument for the whole body. separate trackers tell you what happened. sate tells you what to do next.

the number in the middle is these five bars, each multiplied by its share, added up. that is the whole calculation.

try it

move the inputs. watch the number.

the score reacts the way a body does — gently, and all at once. push training on short sleep and watch recovery pay for it.

the method

honestly earned.

five pillars, each fed by signals your iphone and apple watch already collect. weighted with fixed shares, resolved into a single 0–100 — recomputed every morning.

sate informs. it doesn't diagnose.
recoveryhrv, resting heart rate, respiration, and the architecture of last night's sleep.
nutritionmacros, energy, and timing from the meals you log in seconds.
activitytraining load weighted by heart-rate response, not minutes on feet.
stresshow well your autonomic signals settle — read against your own baseline, not a chart.
habitsthe streaks that compound: water, steps, consistency.
nutrition

training load, honest about cost.

every session is weighted by heart-rate response, not just time on feet. rest is scheduled, not skipped.

ai insights

a coach that has actually read the data.

every insight is an honest read of your own trends — never a generic tip.

the sate insights screen — an ai reading of your own trends
example insight · monday
your sleep debt has compounded across three nights. strength on the bar dropped 6%. hold zone 2 for two days — your hrv will catch up.
example insight · thursday
protein at 95% for nine straight days. your recovery has climbed seven points. the cause is not the cardio.
example insight · sunday
resting heart rate is up four bpm since wednesday. you logged a cold coming on. drop friday's session. catch it early.
works with

apple health. apple watch. no extra device.

all the signal you already have, finally read together. nothing to buy, nothing to charge — and if you already own a chest strap or a power meter, sate reads those too.

switching

bring your history with you.

the reason people stay in a tracker they've outgrown is the years of logs inside it. sate imports them — so the cost of trying something better is an afternoon, not your training history.

  • strong
  • hevy
  • csv

apple health comes across on its own: workouts, sleep, weight and dietary entries you've already logged elsewhere are read on first launch.

one app, instead of five.

every secondary thing the other apps make you pay separately for — quietly included.

hydration

vitamins and minerals against rda — with the gaps flagged.

where it stops

it tells you when it doesn't know.

most health apps would rather guess than say nothing. a missing night becomes an average, an unlogged lunch becomes a default, and the number looks just as confident either way. sate doesn't do that.

no data, no number
a pillar with nothing to read shows —, not a plausible-looking score.
recovery waits for a baseline
it needs about two weeks of your own nights before it will judge one. until then it says so.
estimates look like estimates
a calorie target we inferred rather than measured is rendered faintly and labelled as inferred.
yesterday stays yesterday
when the algorithm changes, past days keep the score they were given. history is never quietly rewritten.
and where it's weakest

without an apple watch, recovery and stress have no signal to read, and each contributes a neutral 50 — half the score's weight, uninformed. partial meal logging drags nutrition down, because sate counts what you told it, not what it imagines you ate. and the first week is the worst week: the score is comparing you to a baseline it hasn't finished building.

the first month

it gets sharper as it learns you.

sate scores you against your own recent history, not a population chart. that is what makes it useful — and it is also why it needs a little time.

  1. day 1nutrition, hydration and habits work immediately — they only need what you log. the score appears, marked as still calibrating.
  2. day 7activity and sleep have enough history to mean something. your free week ends here; you decide whether to carry on.
  3. day 14recovery and stress come online. this is the first day the number is measuring you rather than a rough average.
  4. day 30insights start finding patterns across your own weeks — the correlations that need a month of data to be real.

we would rather you knew this before you started than discovered it on day three.
