Why N°01

More than any watch can do.

Your watch counts steps. The N°01 does much more. It tracks your heart, breath, and body heat all day and night. Each morning, it tells you: am I rested? Am I ready to work out?

N°01 · Schematic
  1. 01
    Sleep

    Light, deep, dream sleep, and every time you woke up.

    A full hypnogram each morning. Four sleep stages, plus your time-awake count. Compare to last week without thinking about it.

  2. 02
    Heart rate · weekly

    Heart rate tracked weekly. Catch stress or illness early.

    Resting heart rate trends — week over week. When it rises, we tell you, before you feel it.

  3. 03
    Daily score

    One daily score. Should you push hard or rest today?

    Calculated overnight. A single number — 0 to 100 — that tells you what your body can take.

  4. 04
    Heart rate · overnight

    Heart rate tracked all night. Even while you sleep.

    Continuous overnight HR plus HRV. Your nervous-system recovery, drawn for you in the morning.

  5. 05
    Body temperature

    Body temp tracked overnight. Know before you feel sick.

    Your nightly baseline, to 0.1°. A spike often shows up two days before symptoms do.

  6. 06
    No fees

    No monthly fees. Ever. Your data is yours.

    You buy the ring, the app is free for the life of the device. Export your data any time, in plain CSV.
