Flowlu allows businesses to manage projects from anywhere.
This software is great!! So easy to enter information and schedules. This solution keeps me very productive! I have a tendency to try to tackle too much at once and end up with an overwhelming number of unfinished tasks. I like the fact that I can share the tasks and lists with anyone just by using their email addresses. Read more
