Cities are huge places by definition, and if you’ve ever found yourself adrift in a big one you’ll know how frustrating and unsettling that can be. The problem is you don’t know the layout, the orientation and most especially the transport system. There’s a ton of city apps out there to help, but for the most part they’re pretty basic, offering train, bus and road guides in a simple form.

Not so with CityMapper. This beauty is a free app for iPhone and Android which gives you exactly the kind of information you need to travel around a big city quickly and easily. How is it different, we hear you ask. Well consider this example – a ‘Take Me Home’ function, which instantly gives you a comprehensive round up of every transport method to get you home fastest from wherever you are at that moment.

And it doesn’t stop there. Instead of just delivering bland transport options from place to place, you’ll also get journey cost, calories burned, and there’s even a ‘stay dry’ option so you can avoid the rain en route.

As you’d expect there’s a great map function available, but it’s things like the live bus time tab that really make this app stand out as a must-have for any city traveler. You get notifications of disruptions, can set up favorite places and in fact everything you need to get around efficiently, except a chauffeur driven limo.

It’s an outstanding app, and although it’s only for New York and London at the moment, there’s a city vote function on the website so you can lobby for your own choice of city to be added in future. Recommended. Get it now.
