V tem diplomskem delu smo se ukvarjali z izdelavo mobilne aplikacije za pomoč starejšim pri klicanju in pisanju sporočil SMS. Pregledali smo obstoječe stanje na tem področju in si zadali izdelati aplikacijo, ki bi pomagali starejšim lažje razumeti dokaj kompleksen operacijski sistem Android, prav tako pa bi poenostavila funkcije na najosnovnejšo raven in povečala ikone ter tako izboljšala preglednost osebam z omejitvami, kot je slabovidnost in podobno. Aplikacijo bomo razvili v prosto dostopnem razvojnem okolju Android Studio in jo kasneje tudi preizkusili v praksi ter dobili odgovor o ustreznosti aplikacije in zadovoljstvu uporabnikov.In this thesis, we addressed the development of a mobile application older people to place calls and write SMS messages. We reviewed the existing situation in this field and decided to develop an application that would assist older people in better understanding of fairly complex Android operating system, implify features for them to the most basic level, increase icons and thus improve the manageability for those with a poor eyesight and other handicaps. The application will be developed in a freely accessible development environment Android Studio and later tested in practice, in order to obtain a feedback on the suitability of application and user satisfaction
