Easy to use; lots of features such as file manager, project management, task list view etc., easy communication with clients through emails or calls. Can be used offline too! The interface is not so good when it comes to mobile phone displays but I know that they have released an android version recently which looks much better than the iOS version currently available. I think this software is worth giving a try because there isn't any other similar product at the moment that gives you all these functionalities in one place. It's very useful for keeping track of my projects and client interactions. I like how easy it was to set up my account with them, they have many different options available that you can pick what works best for you! It's not as user friendly if you're new at using this type of software. If you know about other types of programs then there should be no problem setting this one up also. This program helps me stay organized by keeping track of things such as emails or tasks/projects I am doing without having to use several applications.
