I've been a fan cord-cutting for years. So I think "Subs-Cutting" is an apt name to invent for the equivalent.

Couple of other Android apps which manage subscriptions and are free with high review ratings:

TrueBill looks interesting. I wonder how they make their money? A portion of the savings?

I think truebill makes money from fin-data collection &/or premium plans, now or later.

I glanced at a couple of reviews before and someone said a sub was reinstated by a crafty sub-app dev a few months later. TB seems more of a good info resource, a tad ike slickdeals etc.
