Item Counter

A simple, mobile-optimized list where you can add entries and count each one up or down.

Features

• Add entries - Type a name and add it to your list
• Count up / down - Big tappable +/- buttons per entry
• Persistent - List and counts are saved in the browser (localStorage), so they survive reloads
• Mobile-first - Large touch targets, no accidental zoom, safe-area aware for notched phones

Installation

# Install dependencies
npm install

# Start development server
npm run dev

# Open the app
# http://localhost:4321

How it works

Entries are stored client-side in localStorage (see src/utils/storage.ts), so no backend or database is required. Each entry has a name and a count (clamped to a minimum of 0). Tapping the -/+ buttons updates the count instantly and re-saves the list.
