How it works
On average, a person subscribes to streaming, music, cloud, gym, and app services, and loses track of how much it all adds up to by the end of the month. Prism brings all your subscriptions together in one place, calculates your real monthly spending, and warns you before every charge, so you can cancel what you no longer use in time.
It's simple: add each subscription with a name, amount, and renewal date. Prism handles the rest, monthly total, upcoming charges, statistics by category, and a widget on your Home Screen. And best of all: your data stays only on your iPhone, with no login and no server.
