The app offers an intuitive interface that displays subscriptions on a mini calendar, allowing users to view upcoming charges without complicated lists. It supports 168 currencies, automatically converting them to a single currency based on current exchange rates. Additionally, the fast adding feature automatically finds logos, picks colors, and selects categories when entering subscription names.

Key capabilities include iCloud sync for seamless data synchronization across all devices, a smart import manager that enables easy import of subscriptions from the App Store, Notion, or Google Sheets, and configurable notifications that can sync with calendar or Apple Reminders to alert users about upcoming charges.
