Earth Lock Screen gives a true global perspective

Published by at

Integrating a view of our correctly illuminated planet into a mobile device has been popular since the days of palmtops in the early 1990s, so it's no surprise to see something similar pop up in the Windows Phone Store. Earth Lock Screen, as it sounds, puts our planet front and centre on your lock screen, rotated to the country of your choice and (approximately) correctly illuminated. See below for more...

Cue the 'all alone in the night' intro from Babylon 5 here - what you see here is Planet Earth set in the darkness of space, illuminated only by the sun and by some of its own man-made city light.

From the app description:

This app allows you to set dynamically rendered picture of Earth as a lock screen background or live tile and see which parts of it are in daylight and which are in night at given moment and selected location. Images are rendered and updated completely offline (no network connection involved) twice per hour with almost no impact on your precious battery life.

Good attention to detail in terms of data and battery use, then. Here's Earth Lock Screen in action:

By default your current location, as determined by Windows Phone, is used - here I'm giving permission for the app to alter my lock screen.

My new lock screen - just swipe up to unlock, as usual, of course. The UK's just starting its day, so that illumination pattern looks about right. A two hour refresh sounds a little slow, mind you, I'd rather see an hourly render; (right) you can also set Earth Lock Screen as a live tile, which looks pretty but is otherwise nothing more than a shortcut. And no, there's no double-wide tile option.

Picking the country/region to have centred on the globe and (right) with the USA in focus - and in darkness, since it's currently their night time. In real life, I can't believe so many Americans would leave their lights on all night though(!)

You can buy Earth Lock Screen for 0.79p in the Windows Phone Store or grab a trial (this is fully working but has a watermark over the image). 

A well implemented extension to Windows Phone - more like this, please, from the developer.
