The app shows the Watch's storage info, including stored songs, apps and photos (confirming it will have usable storage space and, likely, different capacity options at differing prices).
The companion app will also let users rearrange Apple Watch home screen app icons, but there are some far more interesting new Apple Watch features than that.
The site says users will be able to customize their Apple Watch faces with digital "monograms," like their initials.
That's a type of feature they're calling a "complication," an optional extra that can be disabled. Another is a feature that tracks a single stock on the Watch face.
The Apple Watch can reportedly display a small red dot on the face to notify you when you have an iPhone notification, and wearers can respond to texts with either voice dictation, actual voice messages or canned default responses, and can switch between these methods on the fly.
With Maps, Apple Watch users can choose whether to enable haptic feedback for turn-by-turn directions, and the Apple Watch also has a number of accessibility features, like other Apple products.
Health and security
Security is a factor as well: the iOS Apple Watch companion app will let users set passcodes for the wearable, and the Apple Watch can be set to wipe if 10 incorrect passwords are entered in a row.
And unsurprisingly activity and fitness plays a big part, with settings like "stand reminders" when you've been sitting too long, activity progress and heart rate tracking controllable via the app.
The Apple Watch will be out in a matter of months, so keep an eye out for more on it as its release date approaches.
And don't forget that you can go test drive the Apple Watch right now.
