Stone Hill Time Card is free productivity apps in the store you’ll want to download and have on hand when you need them.
Pro: When you activate and set up a project, this Time Card app keeps track of how much time it took to complete the task or job.
You can send email to your boss/ client when you work in project as time card.
Con: This app doesn’t track the time of each application you use (see Slife for that), but it could be useful for simply keeping track of the time you’re spending to get jobs done.
However, it helps you to know to visual how much time to spend in each task of the day.
