With HTTP Remote for Wear you can create controls to trigger REST calls for any project you like. Thanks to the wear support you can even trigger these calls from your wrist.

On your handheld you create screens that contain several controls. Each control is linked to a single HTTP call.

This is an open source project. Feel free to contribute at https://bitbucket.org/cappelleh/android-http-remote
