Feature-wise, this new hardware is very similar to the Basalt platform with one major difference - a new display with a round shape and increased resolution. Pebble SDK 3.6 is available to help developers write apps that are compatible with all hardware platforms. New graphics APIs and UI component behaviors assist with creating layouts ideally suited for both the rectangular and round display types. ^LC^ [Get the SDK >{center,bg-lightblue,fg-white}](/sdk/download/?sdk={{ site.data.sdk.c.version }}) ^CP^ [Launch CloudPebble >{center,bg-lightblue,fg-white}]({{site.links.cloudpebble}}) ## New Resources To get you started, we have updated the following sections of the Pebble Developer site with new content and information on designing and developing for the new Pebble hardware platform: * An updated [*Hardware Comparison*](/guides/tools-and-resources/hardware-information) chart - See the hardware differences between all Pebble platforms. * [*Design in the Round*](/guides/design-and-interaction/in-the-round/) - A new section of the Design and Interaction guides with design guidance on how to best take advantage of this new display shape. * [*Creating Circular Apps*](/guides/user-interfaces/round-app-ui/) - A new guide describing how to use new graphics APIs and features. * An updated [*Building for Every Pebble*](/guides/best-practices/building-for-every-pebble/) guide - New information added on how to keep apps compatible with all three Pebble hardware platforms. * Revised [*Platform-specific Resources*](/guides/app-resources/platform-specific/) guide - App resources can now be tagged according to intended usage in more ways than before to allow tailored resources for different display shapes. ## New Examples A number of new example apps have been created to help illustrate the round concept. They are listed below. ### Watchfaces **Time Dots** ^LC^ [![time-dots >{pebble-screenshot,pebble-screenshot--time-round-silver-14}](/images/sdk/time-dots.png)]({{site.links.examples_org}}/time-dots/) ^CP^ [![time-dots >{pebble-screenshot,pebble-screenshot--time-round-silver-14}](/images/sdk/time-dots.png)]({{site.links.cloudpebble}}ide/import/github/pebble-examples/time-dots/) **Concentricity** {% screenshot_viewer %} { "image": "/images/sdk/concentricity.png", "platforms": [ {"hw": "aplite", "wrapper": "red"}, {"hw": "basalt", "wrapper": "time-black"}, {"hw": "chalk", "wrapper": "time-round-silver-14"} ] } {% endscreenshot_viewer %} ### Watchapps **ContentIndicator Demo** ^LC^ [![content-indicator-demo >{pebble-screenshot,pebble-screenshot--time-round-silver-14}](/images/sdk/content-indicator-demo.png)]({{site.links.examples_org}}/content-indicator-demo/) ^CP^ [![content-indicator-demo >{pebble-screenshot,pebble-screenshot--time-round-silver-14}](/images/sdk/content-indicator-demo.png)]({{site.links.cloudpebble}}ide/import/github/pebble-examples/content-indicator-demo/)
