Using the Timer App is as easy as hitting play. The Try Me tool has just two options: Enter a name or description of the project you are working on. There isn’t a cutoff, so add as much information as you want. The other option is your hourly rate. Simply enter the amount you want to charge your client for the time you spend working. You don’t even have to use these two options. You can just hit the “New Timer” button or the little play button at the end of each line to start tracking time. Of course, adding a little more info will make life easier later.
