A better reminders app

Hi,
I love the idea of the stock reminders app to have shared reminders with my wife but I am wondering if there is a free alternative that is better. We are having some problems with the stock app (recurring reminders come up all the time when they are not supposed to, deleting items doesn't always make them go away, hard to add locations...)

Can anyone suggest anything better?

Yea I saw that too but at $5 for each device hats a little pricey for me. I was hoping for some in free.
