A React Native subscription tracker that shows what is due next, what it costs, and where the money actually goes.

• Learning Goal: Taken on as a first real React Native build, following a course as a way into the Expo ecosystem and then pushing past it into auth, analytics, and charting that the tutorial did not cover
• App Architecture: File-based routing with Expo Router, split across an onboarding screen, an authentication group, and a four-tab shell for home, subscriptions, insights, and settings, with a dynamic route for each subscription
• Auth & Storage: Hosted sign-up, sign-in, and password reset through Clerk, with sessions persisted in expo-secure-store and validation and error mapping kept in their own modules
• Interface & Insight: Styled with NativeWind, animated with Reanimated and haptics, with a custom bar chart breaking spend down by category and PostHog capturing how the app is actually used
