Apple Watch has always had faces and complications inspired by astronomy— partly as a nod to the origins of time tracking — but the phases of the moon never matched what we see in the sky. Moon++ is a standalone David Smith developer Apple Watch app that solves the problem.
Moon++’s goal is simple. On your Apple Watch, the moon you see will look like the moon you see in the sky based on where you are on the planet.
On any watch face you can set the astronomically accurate moon as a complication, and you can choose between a simplified or realistic moon design.
Tapping it starts the full app with a dedicated moon finder. The integrated moon phase option is nothing more than a complication, no app.
Spin the Digital Crown to move back and forth on the timeline of the moon location, or tap the screen to go back to the moon location. The new Apple Watch Series 5 is the first model to include an integrated compass, and within the app Moon++ takes full advantage of that. (I’m away from my arrival one day and can’t wait to try it!)
Moon++ is also a completely independent Apple Watch app, something made possible only recently with the new update of the watchOS 6 software. That means you don’t have a companion iPhone app to tuck away in a folder and you can set up Moon++ on the Apple Watch without being pushed to the iPhone.
On the Apple Watch App Store, Moon++ is available for Apple Watch with watchOS 6 for 99. You can also find it from the iPhone App Store where it can be installed on the Apple Watch automatically.
