I was never happy with project management software out there. I wanted something that merged a to-do list and a timeline so I decided to create my own. At the heart of it is a to-do list that can be nested to any level and to the right is a timeline that starts one task when the previous task finishes. There is no need to mess around with start and end dates though it does support that if you want. You create a list of tasks with estimates of how long they will take and the timeline will be generated from that. You can start with a start date and work forwards or a deadline and work backwards. It's intended to be used on a desktop via the browser and on mobile via a native app.
