Sainsbury’s is trialling a new app that promises to cut time spent in store and at the till.

The app, which is being trialled with Sainsbury’s teams in stores over the next few weeks and will be available to Nectar cardholders later next year, allows customers to build a virtual basket of favourite products before they shop, navigates customers around the shop to find their predicted items faster, and scan items at the shelf and pay through a mobile.

Sainsbury’s said the app was proven to cut the time taken to do a shop - reducing checkout time to seconds in testing.

Other upgrades include more flexible delivery slots, with bookings on the half hour as well as the hour, and greener delivery options allowing shoppers to book slots in one vehicle if it’s delivering to neighbours.

“We know that customers’ weekly shop doesn’t start at our front door - they know what they like and they also like that search for a bargain,” said Sainsbury’s digital and technology director Jon Rudoe.

“They still want to come into store - but with limited time, they want to be able to get their shop done quickly. That’s why we’re putting digital firmly at the forefront of our agenda, and putting technology in the hands of our customers,” he added.
