Who Una is for

Built for the curious

Most watches stop at the features they ship with. The sensors are there, but the software is locked down and you’re limited to whatever the manufacturer decided to build.

We kept hearing from people who wanted to go further. They wanted to use the sensors, write their own apps and make the watch useful in ways we hadn’t considered. That’s why UNA has a public SDK, so devs can build their own ideas on real wearable hardware.

POSSIBILITIES

BUILD MORE THAN JUST ANOTHER WATCH FACE.

A new activity mode. A tool you wish your watch already had. A glance for the information you check every day. With UNA, turn an idea into a native wearable app.

// Build for the way you move

Use GPS, heart rate and motion data to create an experience for a particular sport, training session or idea you want to test.

// Make the shortcut you keep needing.

Build focused tools such as timers, widgets or everyday shortcuts, small apps designed to do a specific job well.

// Keep important data close

Create lightweight views that surface a small piece of information without needing to open a full application.

// Give the watch face a purpose.

Rethink what the watch shows at rest, combining different data sources to show information that matters most.
