Abstract
Nowadays the use of technology is rapidly increasing in the educational sphere as all operations can be quickly done with the utilization of these technologies. Adults, teenagers and even children can not imagine their life without smartphones which become an inseparable part of our lives. The aim of this review is to investigate the pros and cons of the usage of mobile applications in the ELT classroom and explore all currently available applications which are connected with teaching and learning English as a foreign language. A lot of studies have been done on the utilization of applications in English classrooms by researchers. The findings show that almost all of the scientists come to the conclusion that students who learnt a language using applications showed good results compared to learners who do not use them. Nevertheless, still more studies should be done to confirm the efficiency of the utilization of smartphone applications on definite language skills and cognition.
