I found the sweet spot between Things 3 and Motion. It's called FlowSavvy.
If you know Things 3, you know what buttery-smooth UI feels like. If you've used Motion, you know what it feels like to have an app think for you. FlowSavvy somehow nails both. The drag-and-drop is silky, the visual design is genuinely beautiful, and when your schedule shifts, it recalculates everything almost instantly. No friction, no fuss. The whole point of a task manager is to get tasks out of your head, and FlowSavvy actually does that. I dump everything in, set priorities, and it handles the rest. That reduction in cognitive load is real and it's significant.
