ChecQ — AI Receipt Scanner & Warranty — an iOS app that turns a photo of a paper receipt into structured data. Built solo, end-to-end, and shipped to the App Store. Snap a receipt and AI reads the store, date and every line item with its price. From there the app tracks warranty countdowns on warrantable purchases, counts down store-specific return windows, and breaks spending down at item level — groceries vs health vs household, not just "$143 at Target". Built as a privacy-first alternative to bank-syncing budget apps: no account linking, receipts stay on device, core flows work offline. Also built a voice-driven shareable grocery list, local notification scheduling for expiry alerts, and PDF/CSV export. Native UIKit, StoreKit 2 subscriptions, 33 languages.
