THE CHALLENGE

Users struggle to keep track of multiple subscriptions across services, often facing surprise charges, forgotten trials, and no clear view of total annual spending.

WHAT WE DELIVERED

A production-grade mobile app.

Orbital is a beautiful, modular Android app that helps users track recurring subscriptions, visualize spending across weekly/monthly/yearly views, manage upcoming payments on a calendar, and receive timely notifications for trials ending and renewals. It features local data, export/import, categories, custom icons, and an optional lifetime premium upgrade.

We built a clean, fast Android app with an 'Orbit' spending visualizer, calendar for renewals, subscription list with rich details (billing cycle, due date, notes, icon), push notifications, settings for currency and alerts, and a paywall for pro features. All data stays on device with export options.
