A calmer start to your run.

Layer helps you decide what to wear for a run. The conditions ahead, the effort you have planned, and the clothing you already own come together in one outfit.

Start with what you have.

Photograph the pieces in your Kit once. Layer uses them in your recommendations, so the outfit on your screen is one you can put on.

Plan for the whole run.

A short, easy run asks something different of your clothing than a long, steady effort. Layer considers your start time, duration, and intensity alongside the forecast.

Let experience shape the next one.

In the iOS app, note how a run felt and keep it with the outfit and weather. It is your own record of what worked. Using that feedback to tune future recommendations comes next.

A familiar voice along the course.

Race Mode plays voice notes from people you invite at points you choose along the course. It is another way to carry something familiar into your run.
