Previously available for $1.99 as a universal binary for iPhone and iPad, National Geographic’s award winning World Atlas app has just gone free in the App Store. It’s not yet clear whether the price drop is permanent or temporary, so better get downloading right away (via AppShopper).
The app has also been recently updated for 2013 with a new look, improved functionality, and brand new features. All National Geographic maps are now available in HD, with better measurement tools for more accuracy. The update also adds up-to-the-minute weather forecast as well as the latest currency conversion rates across the globe. Best of all, you can now download world map layers for offline use as well.
