Do you use subscription managers?

I've stumbled upun a subscription tracker inxy.com and signed up out of curiosity , decided why not to take a look at how much I spend on different subscriptions I use say per month. Turned out 3!! times more I thought OMG! And like a third of that I didn't even use. Saved me quite several grands and that's for free as I'vo only signed up to two-week free trail. Has anyone tried inxy to manage subscriptions? How do you track your subscriptions?
