What it does

List every subscription with its cost and billing cycle. Yearly costs are normalized to a monthly equivalent, and the dashboard shows your total monthly burn plus the yearly figure. Use it for subscription audits — add, sort by cost (highest first), and cancel what you don't use. Everything is stored locally in your browser.

Setup

  • Open app.html in any browser (works from disk via file://). Add a subscription with a name, cost, and monthly/yearly billing cycle; remove entries with the Cancel button. Three fictional sample services are pre-seeded and persist via localStorage.
