How it works
Apple Health in. One plan out.
Cadence reads what your Apple Watch writes to Apple Health, compares it with your own last 90 days, and shapes your training, your food and today’s focus from it. One plan, on the web, your iPhone and your wrist.
The loop
Each step reads the one before it.
Most people run sleep, training and food in three apps that never talk. Here your wrist feeds Apple Health, Apple Health feeds one plan, and what you log or say steers the next turn.

What goes in
Exactly what it reads from Apple Health.
Seventeen readings, read-only, on your iPhone. Nothing is read until you allow it in Apple’s own permission sheet, and an Oura ring or Whoop band that writes to Apple Health counts the same as a watch.

What it does with it
Read against your last 90 days, not anyone else’s.
Five markers, each compared with its own 90-day range and never with a population chart. One night is never read as a trend; a run of days is.

Questions
The details.
Does Cadence work with Oura or Whoop?
Yes, through Apple Health. If your ring or band writes its readings to Apple Health, Cadence reads them the same way it reads an Apple Watch. There is no direct connection to Oura, Whoop, Garmin or Strava.
Do I need an Apple Watch?
No. Training, food and the coach work without one. The watch adds logging from your wrist, and its readings feed the baseline. Sleeping wrist temperature is the one input only an Apple Watch provides, and Cadence works without it.
What does Cadence write to Apple Health?
The iPhone app only reads. The Apple Watch app saves the workouts you record in Cadence to Apple Health, with their active energy and distance, so they count toward your Activity rings, and how hard a workout felt when you rate it.
What happens after one bad night?
One night is never read as a trend. Each marker is read against your own last 90 days, and only a run of days is read as a change.
What else does it look for in my data?
How steady your wake time is, and how far it drifts between work days and free days. And up to three patterns at a time, each with a confidence level and the window it came from. None of them claims a cause.
Where does my health data go?
It is stored in your Cadence account, in a database in the United States. AI features, including a daily insight you can turn off, send what they need to Anthropic, the company behind Claude, which does not train its models on it by default. It is never sold or used for advertising.
Can it count workouts I record in other apps?
Yes, if you turn on workout import. It reads the workouts in Apple Health from the last 90 days on, so training recorded elsewhere counts in your history. It is off by default and asks for its own permission.
Early access
Cadence is invite-only for now.
