Jeani

The personal health agent built around your marathon PR

Personalizing your preventive health.

Apple Watch

Compatible with your device. Jeani reads the watch you already wear and texts you when it matters.

It starts with your goal

Tell Jeani what you are moving toward. Not a step count, a real goal, in your words.

Your choice shapes everything below. Try another and watch the page rebuild.

One continuous record of you

Sleep, heart, training, movement, labs, and the things only you can say. Every stream your Apple Watch already generates, read as one person rather than a pile of apps, drawn into a single thread that ends in one insight, in service of your goal.

No two dashboards look the same

The thread ends up here, inside your Today feed. Jeani rebuilds it around the goal and the body it belongs to. Six goals, six different mornings, and no two of them ever look the same.

Measured against your normal, not the average person's.

It speaks when it's worth saying

No streaks, no confetti, no noise. Jeani writes to you in the terms of the goal you set, and only when there is something worth acting on. It all arrives as texts, straight to your number, with no new app to open. Pick a moment and watch how the conversation goes.

Texts straight to your number

How did this week land on my knee?

Load rose 12 percent and your left knee stayed inside its normal range the whole way. One more week like this and the long run is safe.
