The Australian online retailer that prides itself on its three-hour delivery service in Sydney, The Iconic, has launched a fashion app for the iPhone and iPad.

The app has been built to allow customers to seamlessly sync their accounts across their desktop, mobile and tablet devices.

It will give customers access to over 500 brands and 25,000 products and will be able to share their items with friends and families.

"We pride ourselves on making fashion as accessible and hassle free as possible. The Iconic app means customers will be able to enjoy The Iconic experience wherever their busy lives take them,” Adam Jacobs, co-founder and managing director, said.

“Our team has worked tirelessly on developing a product that is tailored to fashion. High resolution images and a simple swipe and touch interface means you will spend more time picking out clothes you love, and less time navigating menus.”

Customers will be able to complete purchase through the app through a variety of payment methods, including credit card, PayPal and store credit. Purchases through the app carry The Iconic free shipping on orders over $50, free returns for 100 days and three-hour delivery in Sydney.

The app will also give customers instant alerts about exclusive offers and events.

“Our customers live for convenience and our certainly app delivers,” Jacobs said.

The company also noted that an Android version of the app will also soon be made available.
