Shopping List

Project Overview

The Shopping List app streamlines everyday grocery planning. Users create category-wise lists, add products with default quantities and preferred brands, and even store local names for items using multi-language fields. A built-in voice input flow reduces typing friction — perfect for quick additions.

Beyond lists, the app tracks actual vs. discounted prices on every purchase and generates receipts. Monthly spend graphs help users visualize trends and manage budgets. Families can connect and collaborate on the same list in real time, so everyone stays in sync.

Development Challenges

Building frictionless collaboration required careful handling of conflicts and merges when multiple users edited the same list offline. We designed an offline-first data model with queued sync and deterministic conflict resolution to keep data consistent without blocking the UI.

We also optimized receipt storage and price analytics for speed and memory, ensuring monthly spend graphs render smoothly even with large histories. Finally, we implemented robust voice-to-entry parsing and multi-language fields while preserving a clean, approachable UX.

Results & Impact

Users save time planning groceries, keep spending under control with clear price histories, and reduce “forgotten items” through shared lists and finishing alerts. The combination of voice input, receipts, and trend graphs turns routine shopping into a simple, data-aware workflow.
