Read full descriptionHide full description
Mobile Logbook is designed to automate in-the-field logging of activities and extend the features of the eSOMS Suite Narrative Logs module to mobile devices, thereby eliminating the inefficiencies of paper-based logging activities. Mobile Logbook allows the log entries for multiple logs and shifts to be synchronized to mobile devices for viewing remotely via a wireless connection. It allows log entries or annotations to be added on mobile devices and synchronized back to the eSOMS database. While performing logging activities, user identification information (user, date and time) is captured in real-time.
