Mobile applications are becoming an emerging property in today’s world. Delivering high quality mobile applications by improving the quality of the user interface is a definitive guide in building successful mobile applications and will have a significant increase in the market for that application. This paper addresses some issues related to mobile user interface, current input system and user dictionary. After analysing these issues we have proposed a new system by making some improvements to the current input system and user dictionary. In order to improve the current system, we have taken some issues related to one of the most widely used data entry methods ‘Keyboard’ and proposed some improvements by introducing Smart Optimized Keyboard (STOKE). We have provided the results, which include performance, reduction in number of keystrokes, and screen space. This describes the significant change after adopting the proposed keyboard. In the end, we have proposed an optimized way of building up the user dictionary, which assists the user in inserting the input very easily, rapidly and effectively. In a combine, these two will help in providing the best user experience to the users.
