Pulsity

Your worst calls come on your worst recovery days.

Pulsity learns your own baseline from the watch you already wear, then tells you when today's readings have drifted out of it — before you open the position or sign the thing.

Watch, ring or phone. Whatever already writes to Apple Health or Health Connect.

Recovery is well below your normal range. Push anything irreversible to the afternoon, and sleep before you size up.

It takes two weeks to be useful, and it will tell you that.

Most health apps start shouting on day one against numbers that belong to nobody. This one waits until it knows yours.

  1. Day 1

    Connect your watch

    Pulsity reads from Apple Health or Health Connect, so whatever you already wear works — Apple Watch, Galaxy Watch, Fitbit, Oura. Nothing new to buy.

  2. Days 1–14

    It learns your normal

    Two weeks of your own readings become your baseline: the mean and the spread for every signal. No population averages, no age brackets, no idea of what a 34-year-old should look like.

  3. Every morning

    You get today's read

    One number for readiness, and the vitals behind it. Thirty seconds, before the market opens or the first meeting starts.

  4. When you drift

    It says something

    A reading outside your own range triggers an alert with what changed, by how much, and what to do about it — rest, hydrate, breathe, or wait until tomorrow.

Three screens, and one of them is usually enough.

You open it once in the morning. It takes about as long as reading a message.

Trends — the week against your usual week, so patterns surface on their own.

Six signals, each judged against your own numbers.

A resting heart rate of 62 means nothing on its own. It means something when yours has been 54 for a fortnight.

Heart-rate variability
41 ms
The clearest read on recovery. Falls first when you are underslept, fighting something off, or carrying stress you have not noticed yet.
Resting heart rate
62 bpm
Slow to move, which is exactly what makes a jump worth paying attention to.
Sleep
6h 12m
Measured against the amount you personally need, which is rarely the eight hours everyone quotes.
Stress
34
Built from your own HRV, and held back on days you trained hard so a heavy session does not read as strain.
Steps and calories
8,240
Context for everything above. A hard session explains a bad night, and the app should know the difference.
Readiness
71
The single score on the home screen, with every signal that moved it listed underneath it.

Built for people whose bad day costs money.

Log a trade or a decision and it sits next to the readings you had at the time. After a few weeks you stop guessing which state you were in when you sized up, chased a loss, or held too long.

The pattern most people find first is the one they suspected but never had evidence for.

  • Revenge tradingEntries that follow a loss inside an hour, flagged with your stress reading at the time.
  • OvertradingDays where your volume ran ahead of your readiness score.
  • Size driftPositions that grew on the days your recovery shrank.
One month of trades, placed by the stress reading you had when you entered.

Everything left of the line made money. Almost nothing right of it did.

Your health data stays yours.

What people ask

Do I need a particular watch?
No. Pulsity reads whatever is already in Apple Health or Health Connect, so an Apple Watch, Galaxy Watch, Fitbit, Oura ring or a phone on its own all work. The more signals your device records, the more the baseline has to work with.
Why does it take two weeks before it is useful?
Because your normal is the whole point. Until there are enough nights to work out your mean and your spread, an alert would be guessing against somebody else's numbers. The app shows you the calibration progress per signal so you know where it is.
What counts as an alert?
A reading far enough outside your own range that it is unlikely to be noise. The threshold is in standard deviations from your baseline, not a fixed number of beats or hours, so it means the same thing for a marathon runner and for someone who never trains.
Is this medical?
No. Pulsity is a wellness and decision-support tool. It does not diagnose, treat or monitor any condition, and it is not a substitute for a doctor. If a reading worries you, see one.
Can I get my data out?
Yes, any time, from Profile → Export My Data. You pick the range and it hands you every reading as a file. Deleting your account removes your profile, readings and preferences within 30 days.
What happens when I cancel Pro?
You keep Pro until the period you have already paid for ends, then drop to the free plan. Nothing is deleted — your history is still there if you come back.

Two weeks from now, you will know which days to trust.

Connect the watch you are already wearing and let it start counting.

Not a medical device. It does not diagnose or treat anything.
