Microsoft Todo is great for this. It syncs between all your devices, Office365 and integrates with outlook (flagged emails become todo items).

You can make hierarchical folders and the recurring option is super handy.. I run much of my invoicing/AR/AP as just a recurring todo item.

Microsoft threatened to kill my favorite tool, wunderlist, so I stopped using it and avoided their new tool too. I just can’t seem to forgive them. I am not sure what wunderlist provided that I loved, or I might write my own replacement, but nothing has felt as good since.

Amazing Marvin. All the tools of every to do app out there. With the ability to customize everything. You add and remove only the features you need and use. You can even theme it to look exactly like Wunderlist.
