Tunder · Offline Cash Register

TUNDER is a POS app that turns iPhone or iPad into a simple and efficient cash register, enabling merchants to manage sales, products, payments, and reports from anywhere. It supports offline mode and real-time sync across multiple devices, making it ideal for physical stores, mobile businesses, and multi-shop setups.

Set up takes minutes: create products, taxes, categories, and discounts; accept cash, card, checks, and more; print or email receipts; support QR menus for restaurants; manage stock with alerts; and export data for accounting. With secure PIN access and dedicated support, Tunder is a robust, portable alternative to traditional POS systems.
