Todoist is an email and task management application. It has several advanced features, like being able to import contacts from other applications such as Gmail or Yahoo Mail, syncing time for meetings, and providing instant access to notes and tasks. Todoist can be downloaded for free on the Internet but if you decide to buy it, you will pay a one-time fee that will get you full access to the software. The biggest downside to using this software is that you can't use it on your iPhone or iPod Touch because Apple does not allow it. There are many other applications for the iPhone that work quite well, including Google Keep, Google's equivalent. You can either download the Todoist free from their website, or you can download it from another application's website. After you have installed it, you can begin using it by opening up the application and typing in a project that you have created. You can also open up the web interface if you want to. You can import files from external sources like your iPhone, or you can simply type in a text file to see the tasks you have created for the day. One of the big advantages of using Todoist on the Mac is that it is compatible with all versions of Mac OS X. I have tested it on 10.4 and 10.6 and the interface is just as functional on those versions as it is on the current version. I like the fact that it has the same look and feel as Windows because it's really that intuitive. Many people find it difficult to create a new task in Windows, so having the ability to export a task to Mac is a great way to make tasks quickly and easily. There is a specific Web-based editor that works perfectly for making tasks, but there is also an option to view the tasks on the Mac itself if you prefer this.
