The "Apple-ification" as you put it is done pretty well. In place of drag + drop to set a time of day, tasks can be created with inline date parsing. So tasks can be created with something like: "Meeting with Tim at Tues 3pm", and it'd pick that up. It's missing direct support for habits aside from having recurring todos.
If you'd like, I've got a 3-month premium code left over I can send your way. Not affiliated with them, just a happy user.
I too have tried most if not all of the tools in @renaudg's post and have come to the same conclusion: nothing really matches Timeful.
