Much-hyped transport app, Uber, has launched a grocery delivery service in the US.

The Uber app connects user to taxi and hire cars and has attracted widespread media attention for its innovation, with many considering retail deliveries a natural extension of the service.

Uber has been operating in most Australian cities since 2013, with Adelaide and Geelong added within the last two weeks.

In June, Sydney gelato retailer, Gelato Messina, teamed up with the local arm of Uber to run a half day promotion which saw customers give $20 towards a delivery of Gelato Messina product to the customer’s locations.

Uber Corner Store is available through the existing Uber smartphone app, though is currently limited to deliveries in Washington DC.

The on demand product delivery service lets users to order from 100 convenience store items such as allergy medicine, nappies, and toothpaste, via the Uber app.

Other products will include over the counter medicines, snacks, beauty items, office supplies, and baby products.

It is expected that following a trial period, Corner Store will be rolled out to further locations in the US and beyond.
