GetApp.com, an independent marketplace for online business software has released an infographic comparing online project management software solutions to help businesses choose the right product. There are some interesting trends and data on the chart, including their age and size, their emphasis on social media, and whether they offer integration with Google, Intuit and Salesforce products and have their own API as well. There is also information about whether Android or iOS versions of each app are available.
It is a pretty nice collection of different pieces of information and useful if you are in the market for this kind of software.
