Nice selection! I should definietly try some of these apps. The one I can’t get without is Kanban Tool (https://play.google.com/store/apps/details?id=org.kanbantool for android and for ios: https://itunes.apple.com/us/app/kanban-tool/id1096506294?mt=8). It’s awesome when it comes to organizing your day, work, staying in touch with your colleagues while working on a project and keeping up with all your tasks. I can definietly spot a difference in my productivity after I started using it.
