After creating an account with Intervals, you are given your own sub-domain for one of two domains (I picked rev2.projectaccount.com). Intervals is nothing like the simple “to-do list” site you may be used to. The site includes many advanced features and settings you may not get with other services. Similar to other project management services, you can create tasks and assign them to other members of the project team. Time spent on each task can be calculated out into billable and non-billable hours.
Intervals also features a handy timesheet feature allowing for calculation of real time spent for all members of the project team for all tasks involved in the project. Intervals also tracks clients, and can handle multiple projects at once. The free membership only includes one project, all other levels are not free. Many different types of graphs are available to help your team manage its time more efficiently.
At first, Intervals may seem a bit daunting, but the interface is actually very intuitive and includes many features you would expect from a great time management service. If you are managing a large project with multiple members, multiple clients, or have to juggle time sheets and billable hours, I recommend Intervals. They’re one of the few services to give the popular 37signals’ Basecamp a run for its money.
