We sought to build a time/activity tracker that had as few features as possible. A single purpose product that just focused on providing a great user experience.
Fast Track lets you record your time or activity and compile it into an invoice at the click of a button. That's it.
I don't think there's a simpler or faster tracker out there, but I haven't seen them all, so I welcome you to prove me wrong :D
I'm eager to get critical feedback on it and anything - good and bad - is helpful!
