Become familiar with the application starts with the main icons. If you want your application interesting and acted professionally, you will definitely need quality icons, and not her. User gets acquainted with your application from the icons. The greater part of the users decides to download a demo application and subsequently to purchase it just because it catches the eye. The main application icon guarantees its uniqueness and diversity and has a significant impact on creating a first impression of the application. Another factor which influences the buyer’s decision is the UI design, its attractiveness, usability, purpose and functionality. Custom applications for tablets and smart phones can be used as an effective promotional tool that appeals to your potential and existing customers, as a communication tool for external and internal communication. Due to current mobile statistics and industry trends and fast spread of mobile Internet connection these applications are becoming an essential part of enterprises portfolio. We see the icons and pictograms not only in apps and games for smart phones, but also on the websites and in information systems. They are created by the certain rules and each of these groups of icons must match to clear parameters. I’m an artist and graphic designer and I don’t develop the apps or games, because I am convinced that in collaboration with a team of professional developers (programmers and system analysts) I’m able to "bump" or visualize a metaphor of your application or system much better. The final effect of such cooperation, when each person (programmer, graphic designer, and analyst) is doing what he does best, is always at a much higher level. Therefore in this area I cooperate with some companies and people and I’m inclined to further productive collaboration.
