Know

Your rings. Right there.

Raise your wrist and the Protocol rings are the first thing you see: your Protocol Score and the signals behind it, in one glance. Swipe up for the breakdown, recovery, sleep and exertion.

Train

Start with one tap.

Quick Start shows the next session in your plan. Press Start, and the Watch times it, with pause and End on the same screen. No menus to dig through while you're getting ready to move.

Finish

Done on your wrist. Saved on your phone.

When you press End, the finished workout is sent to your iPhone, where it joins the rest of your training. Planned sessions can also be sent from the iPhone app to the Workout app on your Apple Watch, with your permission.

Check in

Your morning check-in. A tap away.

The Watch has its own check-in page. Answer on your wrist, feel the haptic tap, and your answer is waiting in the app on your iPhone.

Questions, answered.

Do I need my iPhone?

Yes. The Apple Watch app is a companion to the Unbroken app on your iPhone, and it gets its data from there.

Does the Watch record my heart rate during a session?

Sessions you start from the Unbroken Watch app are timed and sent to your iPhone. If you record with Apple's Workout app or another device, the heart-rate data reaches Unbroken through Apple Health.

Is it free?

The Unbroken app is free to download from the App Store.

What is the Protocol Score?

A decision-support score that places your sleep, HRV, recent training load and a short check-in beside today's plan. It is not medical advice or a diagnosis.
