This eBook looks at apps for business English students. First, it introduces important distinctions (native vs web-based; free vs pay for; apps for different operating systems). Then, it presents a selected number of apps chosen by the authors in the following categories: language skills (speaking / writing / listening / reading); language (grammar / vocabulary / pronunciation) and finally, business. Each app is described briefly; then, ideas are provided for using the apps autonomously on a Smartphone and / or tablet. This book contains Apptivities for use in the language classroom, followed by ideas for students on the move. The students' book can be downloaded free of charge by learners as part of their business English course, or bought independently for 0.99 cents.
