Your daily signal, in one place.

Recovery, strain and sleep share one clear view with your chosen headline metric. Tap through for the readings and context behind a score. Older readings are marked so they do not pass for today’s data.

Maps

A programme you can put into practice.

Follow the exercises, log your sets, reps and weights, and see what you completed last time. Coach can propose a shorter next session for you to review and accept; your programme never changes silently.

Shop

Terrifuel, straps and the band, in your own currency.

One account, one bag, one checkout. Prices convert to wherever you are rather than showing dollars and surprising you at the end, and anything on its way to you is one tap from every screen.

Fitness age

An estimate you can look inside.

See the inputs and limitations behind your fitness-age estimate. It is a fitness signal, not a clinical assessment. Explore it alongside your trends rather than treating one number as the whole story.

Make it yours

Ten colours. Pick one and watch the phone change.

Every colour here was captured from the real app rather than filtered in a browser, so what you are looking at is the actual build. The recovery, strain and sleep rings keep their own colours on purpose — those carry meaning, and a colour that means something should not follow a preference.

Before you download

A few things worth knowing.

Do I need to buy a V1?

No. Programmes and workout logging work without a new wearable. Apple Health imports are available on iOS, subject to your permissions and available data.

Can I download it now?

The native app is in development. Choose iOS or Android for launch updates. We will link directly to the stores when the app is available.

What is included for free?

Daily scores, programme access and workout logging are included in Free. Pro starts at $7.99 per month. Hardware and supplements are separate.

What happens when I share my week?

You choose when to open the share sheet. The summary contains completed-session and active-day counts, without health readings or profile details.
