Build a Subscription Management App
Help users take control of their recurring expenses by building a subscription manager that tracks renewals, notifies about upcoming charges, and offers monthly budgeting insights.Most users are subscribed to multiple services like Netflix, Spotify, Amazon, and various SaaS tools. An app that consolidates and monitors these payments is highly relevant. This project teaches you billing APIs, notifications, financial tracking, and calendar integration—core concepts in utility app development.
Allow users to manually or automatically import their subscriptions, categorize them, set custom renewal reminders, and generate analytics for monthly recurring spending. Offer calendar sync and smart cancellation suggestions.
Add & Categorize Subscriptions
Users can add subscriptions manually or through email/transaction sync and assign categories like Entertainment, Utilities, SaaS, etc.
Renewal Calendar & Alerts
Send reminders ahead of upcoming subscription renewals with smart calendar integration and alert logic.
Monthly Expense Summary
Show monthly spending breakdown by category, upcoming charges, and recurring total predictions.
Smart Suggestions & Cancellation Reminders
Highlight rarely used or duplicate services and recommend cancellation to optimize spending.
Users register and input or import their subscriptions. The app stores renewal cycles, sends reminders, tracks spending, and visualizes data in clean dashboards. AI-based logic detects subscriptions that haven’t been used recently and suggests potential cancellations or budgeting improvements.
- Users add subscriptions by service name, amount, billing cycle, and category.
- Optional: import from transaction emails or bank feeds using APIs like Plaid or SaltEdge.
- Get push/email alerts 3 days before any due payment.
- View a monthly dashboard showing all active and upcoming subscriptions.
- Receive smart tips like “You haven’t used this app in 60 days” or “Your Spotify and Apple Music overlap.”
