How Kim works

Three simple steps. No dashboards to decode.

Kim turns what you track into a calm, ongoing conversation you can actually follow.

1

Connect Apple Health

Kim reads the Apple Health data you choose to share — workouts, sleep, heart rate, and more — so it has real context, not guesses.

2

Track what’s going on

Log how a workout felt, what you ate, or how your energy has been. Quick check-ins, no spreadsheets.

3

Understand the patterns

Kim helps you reflect on patterns across your training, recovery, food, and habits — explained in plain language.

The problem

Your phone tracks everything. You still don’t understand it.

Most tracking apps give you charts, scores, and rings — and still leave you guessing what to actually do tomorrow.

  • Sleep scores that change with no clear reason.
  • Workout stats that don’t connect to how you actually feel.
  • Food and supplement advice that contradicts itself online.
  • Energy dips you can’t link back to anything specific.

Kim’s job is to be the layer that turns your tracking data into a real conversation that makes sense for your body.

Sleep, workouts, food, supplements, energy, recovery, habits — plus the Apple Health data you choose to share. All in one calm place.

Sleep conversations

Talk through how you slept and what might be affecting it — bedtime, screens, stress, training load.
