I like that it is easy for me as my work requires more of business management than writing proposals or handling paperwork, so having an app with all this information available makes things much easier! It has been very helpful when we are out at meetings where our phones aren't allowed but there's still internet access (like airports). Nothing really right now - however they do have some new features coming soon such as being able to input hours into time cards directly from the application which will be extremely beneficial!! Make sure you get everything set up correctly before using them during actual project/job sites though because sometimes after saving something doesn't save properly until next use etc.. Also make sure your phone can handle apps well otherwise loading new pages takes forever. Having multiple people working together throughout different parts of the world while also trying to manage projects within those jobsites without any paper documents just made life SO MUCH EASIER. !
