Unofficial National Geographic app that allows you to view the current and past photos of the day as well as Nat Geo's Daily* Dozen.
Add a widget to your home screen so that you can see the latest photo, choose your favourite past photo or see a new random photo every hour.
Set your favourite photo as your wallpaper or let the app automatically choose a new random photo every hour.
Note: National Geographic add the latest photo of the day at approx 05:00 GMT.
* Daily Dozen is not quite daily. Nat Geo usually publishes a new dozen Monday-Friday.
