Your city is a treasure hunt. Thousands of landmarks wait on your map as ghost silhouettes. Find one, photograph it, and it turns to colour and joins your collection, with its story. Every landmark you capture fills in your city map. Collect whole sets, from every church near you to every bridge, with a walking order to follow, and watch your city fill in one walk at a time. Known landmarks are recognised from where you're standing and come with real facts: architect, year, style, sourced from open data. With LookUp Pro, the landmark greats of Glasgow, Scotland, London and San Francisco appear as silhouettes sculpted from real laser-survey data. And it isn't only landmarks. Point LookUp at any building, anywhere in the world, and in seconds you get its architectural style, era and materials, explained in plain language, with the one visual cue that helps you recognise the same style on the next street.
