Travelling abroad with an iPhone, one thing I always miss the most is cell data. While theoretically I could turn on roaming, I would have to mortgage my house to do so. And this also means that unless I find a Wi-Fi hotspot I’m stuck without the lovely Google Maps that I, as many others, have grown so accustomed to. And with my wife making extensive use of the handy My Maps feature of Google’s to plan our trip, this is even more depressing. And then I learned about The Cartographer by Tasty Pixel.
