With the purpose of developing a strategy for supporting informal learning in the workplace, this study investigates the possibilities of launching an educational mobile application adopting various Web 2.0 tools as a personal learning environment. Functionalities including RSS (Really Simple Syndication), podcasting, Web searching, and microblogging were integrated into the app which is named 'MobLearn@Work” to support workplace learners´ individual learning activities which are task-oriented. The article reports on the details of designing and developing the app, from both technical and theoretical perspectives. Optimistic results from the study informed possible ways of implementing educational apps to enhance workplace-learning performance from theory to practice. Recommendations for further research are presented by end of the study.
