We really think it's better than the equivalent apps from our competitors, like Lonely Planet and National Geographic.
In the premium version (World Travel Atlas - Premium - only £1.79) you get loads more of the atlas pages. Covering topics like security, ski destinations, museums and art galleries of the world, phases of the moon, where and when solar/lunar eclipses will be , plus all the maps and climate info you'd expect for a top quality atlas.
I thoroughly recommend it, but then I suppose I would :)
