I had a dream to write the maps a long time ago. Convenient maps that do not require an access to the Internet with the actual data, fast and work on any device. After I worked as an engineer in Google Maps that dream only became stronger, and at some point it turned into the particular actions.
If it's interesting, I'll write something as I was leaving Google Zurich, and at the same time all around did the square eyes:) and then I with me friends were writing a project for almost a year.
The result of all this was the off-line maps for the iPhone and iPad released on April 12, soon there will be ready versions for the android, Mac and Windows.
The idea is as follows. You are going to go to another country with some purpose, for example to relax, and take along your trusty android or iPhone / iPad, MacBook or laptop with Windows, or all together.
Before you travel, you install the application and quickly download the desired map of the country.
United States and Russia, of course, will be slower, but, for example, a map of Belarus is 45 MB, Switzerland is 58 MB (soon the next version will be released, there will be all the countries compressed for a quarter).
Yes, the program is free.
