With Session Log you can efficiently create a structured log of a testing session (session based testing), a meeting (i.e. taking the minutes), a lecture, a sports event, or ... Each log entry has a tag, a timestamp and some text you enter or a picture from your library or device. You can add your own tags and the tags can be used for filtering the log entries. While you create the log, the application continuously maintains a statistic showing how time is spent. You can also start a count-down timer if you want to time-limit the logging session. The log and statistics together with the pictures and graphics can be exported by email or via the Finder for further processing.
