The app is perhaps more geared towards Windows 10 on the desktop more than Mobile, so that you can appreciate the detail on a larger display, but it's still fun to look at and tinker with on the phone. Here are some screenshots:
The satellite views of Planet Earth can be set by time or automatic, and you can tie all this in to your wallpaper/Start screen background, and to your lock-screen (again, on phone or desktop); (right) proof, here's my Lumia 950 lock screen on the phone, within 15 minutes of real life!
Our planet at night like you've not seen it before! Choose between multi-spectral and visible light; (right) animations are available of the last 24 hours of imagery, these are also stunning.
You can grab this for free in the Store here. Extra functions (including zooming) are available if you go 'pro' within the application for a small in app purchase - but this is very much optional.
