The user interaction with mobile devices has dramatically improved over the last years. Increasingly we rely on smartphones and tablets for a wider range of tasks. Modern mobile devices enable users to access, manage and transmit multiple types of media in an easy, convenient and portable way. In this context, the playback of videos on mobile devices becomes a usual activity. Many works regarding video annotations have been made, but few are concerned with the mobile scenario. The ability to add annotations and to share them with others is a content enriching process which can improve activities from educational to entertainment purposes. In this paper, we present an intuitive tool that allows users to perform temporal video annotations on mobile devices. Using conventional tablets and smartphones equipped with the Android operating system, text, audio and digital ink annotations can be made on any video. It is possible to share text annotations with other users and play multiple annotations at the same time. The several display sizes and the possibility to switch between portrait and landscape mode have also been considered.
