When used with other available downloads, many of the time systems can be integrated with Gmail and Hotmail accounts as well as mobile phones.
Technology has made tracking time an automated process. The difficulty is unplugging long enough to get actual work done. Checking, updating, and syncing time can become too habitual for good work practices, so be sure to come up with a plan for tracking your time and stick to it. Only modify your plan if the change will ultimately save you time.
Ultimately, Google Calendar offers the best synchronization and versatility. If a Project Manager sets up Gmail accounts for team members that will be included in planning and implementing, and he then creates a calendar giving all members access to it, he has created a virtual log where all participants can connect and create a fluid plan for completing the project. This will not answer every interactive need of his team, but it is a good start.
