Your personalized health agent

Tell Jeani the goal you are working toward. It combines all of your health data and turns it into the small things that move you closer, every day.

Compatible with Apple Watch

See injuries before they happen

Every watch on the market counts how much you move. Jeani measures how well, joint by joint, from the sensors already on your wrist. Mobility, balance, load and smoothness, read continuously, at a resolution nothing else on your body comes close to.

That is how a problem shows up here weeks before you would feel it. A hip quietly taking less load. An ankle drifting away from the rest of your chain. You see it while it is still small, and while there is still time to do something about it.

  • Every joint read separately, not one number for your whole body.
  • Continuous, from the watch already on your wrist.
  • A drift shows here weeks before it becomes an injury.

Your right ankle has drifted for three days and sits fourteen points below the rest of your chain. Nothing alarming, which is why it is worth a look now.

Every goal reads differently

You tell Jeani what you are working toward. It combines everything you already track with what it reads from your wrist, and builds around that goal. Two people wearing the same watch open two different screens.

Connect what you already wear

Jeani lives on your Apple Watch and your iPhone, and everything in Apple Health comes across. If you wear something else, connect it straight to Jeani or let it flow through Apple Health first.

Jeani texts you. You decide how often

A reading most mornings, and a couple more through the day if you want them. Turn it down to once a week, or off. Nothing is ever repeated, escalated or turned into a streak.

There is an app, and it holds the whole picture when you want to sit with it. Most days you will not need to open it.

And you can ask it anything

There is no dashboard you have to check. Jeani lives in your messages, and you use it by saying things, in plain words. Here is what to say.

  1. ask the harder questions

    why have i felt so flat the last few weeks

    Three things moved together this month. Your bedtimes drifted about forty minutes later, your tuesday sessions got longer, and you have been sleeping through heat. The heat carries most of it, and it breaks on saturday.

    Some questions need weeks of data and every source at once. Jeani reads them together and comes back with the story rather than the numbers.

  2. see it drawn

    have i actually been getting better this month

    Your hrv has spent the month climbing out of its usual range.

    hrv, last thirty days
    this week your usual range
    thirty days agotoday

    When the shape of a trend carries the answer, Jeani draws it instead of describing it.

  3. give it a mystery

    my sleep has been terrible all week and i cannot work out why

    Your worst four nights all followed days you trained after seven. Nothing else lines up as closely. Move thursday earlier and we will see whether the weekend reads differently.

    When something feels off, Jeani goes looking through sleep, training and the days around them until the story holds up.

  4. go long, by email

    build me a plan for the half in october

    That deserves more room than a text. It will be in your inbox shortly, built around your right ankle and your tuesday club runs.

    Anything long arrives as a proper document in your inbox. A training plan, or a month pulled apart.

  5. get a nudge

    text me thursday at five to stretch before the gym

    Done. Thursday, five o'clock.

    One off reminders at the moment you name. Change your mind and it is cancelled just as easily.

  6. tell it once

    for the record: knee surgery, march last year

    Remembered. That shapes how I read every run from here.

    Injuries, the race on the calendar, what to call you. Said once, carried into every conversation after, long after the thread scrolls away.

  7. send it things

    coach-plan-october.pdf pdf · 6 pages

    Read it. Week three stacks the hard sessions right where your recovery usually dips. I would move the tempo run to wednesday.

    A coach's plan, a screenshot, a lab result. Send it across and Jeani reads it against everything it already knows about you.

We are opening a small group at a time so the first weeks are read properly. Leave your email and we will let you know when it is your turn.

One message when it is your turn, and nothing else.
