Mobile Expense Tracker — PWA-style Expense Manager (HTML/CSS/JS)

A mobile-first, PWA-style expense tracker built with pure HTML, CSS and JavaScript — no dependencies, no server, no database. Add daily expenses with amount, category, note and date; see today / this-week / this-month summary cards; get a category-wise spending breakdown with visual bars; search, one-tap delete and clear-all with confirmation. All data is saved offline in the browser's localStorage, so it works without internet and nothing ever leaves the device. Includes a PWA web manifest + app icon so it can be installed on a phone like a native app. Perfect beginner project to learn DOM manipulation and localStorage, and genuinely useful as a daily kharcha-tracker.
