9 Great iPhone To Do Apps

Awesome Note +ToDo (US$3.99) is a full-featured list app that offers plenty of customization options. Managing your tasks and to do lists is easy, and the app syncs with Evernote and Google Docs. I also love the monthly calendar view for getting an overview of your tasks for the coming weeks. Since Awesome Note has so many features, it can take some time to figure out how everything works. Overall rating: 5 out of 5 stars.  

Some people may balk at the price tag, but the 2Do list app (US$6.99) is packed with features and has a ton of functionality. You can assign actions to each task -- like phone calls or emails -- and the app syncs with your contact list. The tabbed interface is easy to navigate, and 2Do also brings voice recordings, alerts, Twitter integration, and a wide array of customizable features. It can be a bit confusing to use at first, but the 2Do list app for iPhone is a clear winner. Overall rating: 5 out of 5 stars. 

Like most apps on this list, Todoist combines a web version and an app to give you access to your tasks nearly anywhere you are. Those tools are powerful, organizing tasks by project, offering a smart, natural-language scheduling tool, and setting automatic reminders for any task with a time attached to it. The US$29/year premium version adds integration with calendar apps for a single view into everything you have to do for an entire day and expands the reminder functionality. Overall rating: 4.5 out of 5 stars. 

Wunderlist (Free) is a stylish to do list app that syncs with a corresponding desktop client for Macs and PCs. Outstanding tasks are clearly noted, and priority items can be starred for easy access later. Although a monthly calendar view would be helpful, the Wunderlist app displays upcoming tasks in various ways. Overall rating: 4.5 out of 5 stars. 

The ToodleDo app (US$2.99) has a simple interface that makes it easy to add new tasks to your to do list. For each task, you can set priorities and due dates, assign it to folder, schedule reminders, and more. Folders are especially helpful for keeping tasks organized. However, the ToodleDo list app has a confusing priority system, and I wish it would set app badges as a default. Overall rating: 3.5 out of 5 stars. 

Orchestra (free) is a decent to-do list app for an individual. Put it in the hands of a group, though, and it becomes something special. That's because Orchestra allows you to assign tasks to anyone with an email address or phone number (ideally they'll also have the Orchestra app, but it's not required). Users can see who's taken on what task, when they've done it, and chat about it all via the app. While it's missing some important features, and takes an unorthodox approach to deadlines, some people will love it. Overall rating: 3.5 out of 5 stars.

The TeuxDeux app ($2.99) is an iPhone-specific version of the web app of the same name. Its stylish, spare interface places emphasis squarely on your to-dos, but doesn't offer many features besides syncing with the web app and rearranging items. Its productivity focus will be perfect for some users, but others will require more features to get things done. Overall rating: 3 out of 5 stars.

Air To-Do (US$1.99) is very easy to use, and I love that the app is integrated with Facebook, Twitter, and email. However, the Air To-Do list app is much simpler than its competitors. You can only create one to do list (although with unlimited tasks), so Air To-Do is worth a look if you only have a few tasks to complete each day. Overall rating: 3 out of 5 stars. 

Ita's developers advertise it as both a to-do app and a list-making app. Trying to be two things is a real problem in this case. As a list app, Ita is solid, if basic. As a to-do app, it lacks crucial features such as reminders, due dates, priorities, and a web version. If you just need to keep lists without worrying about when you'll get things done, Ita is fine. But if you're focused on productivity, you'll probably need to look elsewhere. Overall rating: 3 out of 5 stars.
