I have, at least for the free trial amount. It didn't really stick for me, because of no mobile app so I can't add transactions on the go, and the budgets just seemed...forgiving? I want to control my spending, I don't want to be told it's okay and that I can spend more. At least for me, I want hard cut offs. It's a fine service, it just didn't work for me necessarily. I also don't use their multi-currency support as I don't travel or have multiple currencies.
