I like that it's free, easy to use, has many features (such as multiple companies), can be used for both freelance jobs or full-time positions with employers/clients. You have to download some plugins from their website if you want more advanced functions such as creating custom fields which is not available out of box. Also there are no mobile apps yet but they said its coming soon. We're using this tool mainly because we need an online freelancing platform where our clients could post projects without having us manage everything related to them (e.g., payment).
