I really like Todoist but its planning capabilities don't compare to TimeTune. I'd like to use Todoist exclusively but it is a hassle compared to TimeTune when you want to micro plan your day. For example, in TimeTune, all you have to do is drag and drop the task and it auto adjusts the time for you and you get a easy accurate view of how much free time you have. With Todoist, if you want to rearrange several tasks, you have to open the task, type out the time and that can become a hassle when you have several tasks that you need to edit. Can you imagine if Todoist had that extra feature where you can set the duration for each task? And as you move it up and down the time auto adjusts? That update alone would make todoist the ultimate planner. But at this point TimeTune has that label. But for now, using them both at the same time works out fine.
