This paper describes an application implemented on several mobile phones with open OS (Windows CE and Symbian 6 and 7 compatible). This application is a real tool used for experimentations, and which gathers frequency uses, duration and navigation (press on the keypad and history of windows opened). Without any constraint for users, this application makes it possible to identify functionalities used (directory, calendar, SMS' number received and sent...), duration and navigation (keys pressed...). In addition, this tool allows to carry out remote tests with real customers. An operation description and different results obtained are presented. Furthermore, the limits and advices are also described.
