Do is a free productivity app for the iPhone that incorporates a number of well-designed features you'd normally only ever see in a paid app. The result is a fun, easy-to-use, and generally very streamlined task management and productivity tool that will work well for most iOS users in need of a new app for managing their tasks.
When you first start Do, you are given a short tutorial on how to add new tasks, mark them as complete, and navigate between screens. This takes only a few seconds, but you are also required to create an account that you will then need to log in with in the future; this, of course, syncs with other iOS devices, though, which is a nice touch. The interface is very intuitive but there are a lot of features built in so it may take you a bit of time to find things or master the swiping methods used to interact with them. Still, it's nice to be able to switch between lists, views, and contacts so rapidly; and creating new tasks is very easy. Combined with contact list integration and calendar listings, the app provides a huge range of options.
If you are looking for a well-made, free productivity app for your iPhone that isn't too scaled back or too cumbersome for quick task management, download Do. It is easy to use, offers a range of options for your device, and there are no ads or other distracting interruptions to slow down its use. It's a great all-around task management tool.
