Pebble 2 smartwatches are on their way to Kickstarter backers, and firmware 4.1 will be ready and waiting for them.

## Heart Rate Monitor API

The HRM APIs allow allow developers to query the user's current and historical heart rates. We've provided a simple to use API which caters for the most common use-cases.

Find out more in the [_Heart Rate Monitor API guide_](https://developer.repebble.com/guides/events-and-services/hrm.md).

## AppGlance REST API

The AppGlance REST API enables developers to programmatically set the icon and subtitle that appears alongside their app in the launcher. Developers can push slices to the their app's glance using their own backend servers by sending HTTPS requests to the timeline endpoint.
