I have been using this app for almost 2 years now, it's easy to use with all of my devices as well (computer at home office desktops) so no worries there! There is nothing that i dislike about kreers application or website itself but just like everything else in life - you gotta pay attention sometimes because some things are not intuitive especially if don't know how they work yet :) It works great together when working from different locations/time zones at same project- we can communicate easily via messages which helps me manage time better than what would be possible otherwise without such software between us!
