I bought this app today and spent several hours learning it well enough to put a couple of task sets into it. It does have a learning curve as it is not what it looks like (a Gantt chart with tasks). It is instead a task list with Gantt-like display option. Once you wrap your mind around that and don't try to list every item in sequence but by priority or date (using it like a task list, in other words, not a Gantt chart) then it gets a lot easier. It appealed to me because of that timeline display feature and the ability to track multiple lists at once (each with its own timeline display if desired), which make it easier to track deadlines coming as well as shifting priorities. I have sometimes previously used a Gantt chart for tracking to do and other items, so recognize the shortcomings of a Gantt for that as well. Use the right tool for the task (this for lists of prioritized to do items, a Gantt chart tool for project requirements and status in a sequential display), and both will work well for you. I like the added clarity that this approach gives to task lists, and it does do what it says it will in a way I haven't seen any other do. It's a fine product at a reasonable price for what it does and no I have no connection with the developer except as customer. Understand what you're getting into and you won't be disappointed.
