Even the fact that it's freeware can't save this disappointing tool, whose sole purpose appears to be showing how long you've worked. Activity Indicator's simple interface can be placed anywhere on your desktop and stays on top of other applications. When you scroll your mouse over the bar, a small window appears with "Working activity during the day" followed by a percentage. The meager Help file doesn't provide the context for the percentage or what it's based on.
Unlike other programs in the category, it doesn't offer notifications for breaks or provide any reports on usage. The publisher's listed Web address takes you to a site that didn't have anything to do with software, and instead seemed to be selling magazine subscriptions. Users should avoid this odd little program, which can't tell you any relevant information about your PC activities.
