Two new interesting watchOS apps are out this week that could add some usefulness to the Apple Watch. Cardiogram uses the heart rate sensor to provide your heart rate history directly on your watch, and Zepp Golf Swing Analyzer turns your watch into a game coach.

On its own, Apple Watch reads your heart rate regularly in the background but only appears in workouts and from the heart rate glance. Viewing a history of your data means using the Health app back on the iPhone.

But watchOS 2 lets apps access sensors including the heart rate sensor, and Cardiogram leverages that capability to create a heart rate graph that you can view on Apple Watch. Another feature of native apps is the ability to include watch face complications, and Cardiogram now does just that so you can see a recent heart rate reading and time just by glancing at the time.

Here’s Cardiogram’s full list of changes:

Cardiogram is available for free on the App Store.

And just in time for summer (and Father’s Day), the Zepp Golf Swing Analyzer iPhone app has an Apple Watch companion that presents streamlined data without you needing to look at your iPhone. The new app shows you swing metrics, change clubs, and view swing history when you golf and your iPhone is paired with a Zepp 1 or Zepp 2 sensor ($99-$149).

Here’s Zepp’s full list of changes in the latest version:
