Our philosophy

It's simple! To produce unique, innovative, interesting and fresh technological solutions.

At Useappility we put a lot of effort on the usability and functionality of our applications by adopting a user-centered approach from the very early stages of the design. We develop applications for all available operating systems (Android, iOS, Windows Mobile, FirefoxOS).

Our users are preschool and early school pupils, professional as well as people who want to become partakers of the technological revolution taking place while portable computing devices become more popular, but have little or no experience in using them.

We aspire that our applications will help younger users to better understand concepts and situations through a playful way, will assist professionals handle the routine and will help lift the peculiar social exclusion suffered by novice users.

We love innovation in all its forms, not for the sake of innovation itself, but as a means to reach a better result. We do not stop lashed on entrenched perceptions but we keep on researching by combining technologies that have been successfully applied in different fields and offer technologically advanced applications that promote the level of interaction between the users and their computing device.

In Useappility we develop applications driven by the needs and requirements of the users who make up our target group . The focus of the development is on the users and what they want to do with an application, rather than what the application can do for them!

For Useappility, quality consists a major commitment in every aspect of operation. Continuously improving our customers / users satisfaction is our principle aim. Towards this direction an integrated Quality Management System is implemented and has been certified by TUV HELLAS (TUV NORD) according to ISO 9001:2008.
