TaskRabbit is a unique service that lets busy people offload their tasks to those willing to do them. It costs a small fee, but you can have your groceries delivered, laundry done and dogs walked before you return home from a busy day at work.
When it launched, the service was web-based only, but TaskRabbit recently developed an iPhone app that lets you manage your tasks on the run. You can create a new task, monitor the progress of a task and even price a task using information based from the TaskRabbit service. It lets you add descriptions using a voice recording or images so the person completing your task knows exactly what to do.
It's an interesting use of modern technology that melds your mundane routine with the power of the crowd. And it's now on the iPhone.
