Android Wear developers will soon be able to create customized designs for their smartwatch faces.

Google will soon be releasing an official API that will enable developers to create third-party watch face designs for Android Wear devices.

Custom watch faces is one of the most requested Android Wear features developers ask for, said Wayne Piekarski, a senior developer advocate for Google, in a post on Google+.

"Customization has helped Android thrive, and the same will be true for Android Wear," Piekarski said. "We are working to make this as simple as possible for you so that it’s easy to make good-looking faces that work well across multiple form factors, conserve battery, and display the user’s card stream nicely."

Developers can already create their own watch face designs with "a fair bit of tweakin,g" but Piekarski suggested developers don't post their own designs until the official API is released in order to ensure stability and compatibility with future versions of Android Wear.

Piekarski did not reveal exact timing for when the official API would be available but said some of the features likely wouldn't be ready until Android Wear is migrated to Android L, the newest version of Android, which would be "later this year."
