Introduction. Internet has completely changed communication among people in today's world, especially among young users. The objective of this study is to establish the frequency of Internet use by teenagers, and most used apps. Population and methods. This was a crosssectional study. In November 2013, students attending two mandatory secondary schools in Albacete were invited to complete a self-administered questionnaire with close-ended and open questions. Questionnaires were completed in the classroom, either "online" or "with pen and paper". Answers were entered in a computer database using the SPSS 17.0 software. Statistical analysis included a comparison of proportions (χ² test) and mean/median values (Student's t test/non-parametric tests). Results. Nine hundred and sixty-seven students participated; their mean age was 13.8 years old (range: 11-20); 53.5% were girls. Most students (70.9%) lived in the city. Most belonged to a middle (51.3%) and high (34.8%) socioeconomic status. Also most students went online on a daily basis (73.4%); only 0.9% indicated that they never did. The most frequently used apps included WhatsApp (77.1%), social networks (70.1%) and music apps (66.6%). Among girls, the most common Internet use was social networks (p= 0.004), WhatsApp (p < 0.0001), Instagram (p < 0.0001) and listening to music (p= 0.004). Boys most commonly used the Internet to browse the web (p < 0.0001), Skype (p=0.001), play (p < 0.0001) andwatchmovies or TV shows (p= 0.035). Conclusions.
