I would like to talk about how we made the design for the mobile version of the city directory of 
DoubleGIS . If you are not interested in the design, then the post can still be refused by the useful fact that you can see the application functionality in the screenshots, which will be implemented in the future.

 We were approached by the company DoubleGIS, which is creating reference books of organizations with maps of cities, so that we develop graphic design for the new mobile version of the 
2GIS program. The main requirements for the interface have become easy to learn and correctly displayed on screens with non-standard resolution. The program will work on Windows Mobile, Symbian and Android platforms. On the touch screen should be able to control both the fingers and the stylus. On devices without touch screens - using hardware controls (joystick, buttons).
We started with the main screen, which allows you to go to the main functions of the program. The alignment was taken on a bright emotional design, but taking into account the requirements of the corporate style guide, DoubleGIS.
