There are several that I like. This video walks you through them:
I actually do it all in Evernote which is great because it can be shared in the cloud and you can really set it up / customize it any way you like to make it work as a To Do List. Of course this is also great because you have your apps for your phones and with the paid version you can embed any flie type in a note. So for example I was just in a session with a client where they have a number of loans on the books. I have the effective interest schedules in notes in Evernote so I can easily search that client’s notebook for “Loans” and they come up. I also tag any notes within that client’s notebook with a tag called “follow up” and when I filter the client notebook for that tag I now have my to do list for that client. I can then save these searches so that I can access that to do list for that particular client in one click.
