I’m a fan of David Smith’s apps for the Apple Watch. He gets what makes an app great on the Watch, and his focus on health and fitness resonates with me. David shipped some solid iOS 10 and watchOS 3 updates today – but Background Refresh in Sleep++ is my favorite:

Sleep++ has been updated to take advantage of the new Background Refresh mechanism in watchOS 3. Now rather than performing all of the sleep analysis in the morning when you wake up, instead it is able to analyze your night while you are sleeping. So when you wake up only the last few minutes of the night need to be processed. The end result of this is that you should barely seen the Analyzing Night progress dialog any more.

I have a feeling that Background Refresh will make me re-evaluate several Watch apps I stopped using (except David’s – one of the very few apps on my Watch).
