A new property search app has launched whose listings are all powered by Zoopla.

Patch claims to be the first property app to be fully native to the iPhone, for which it has been specially developed.

This is claimed to give it a better look and feel, and to make it more intuitive and faster.

It also allows messaging within the app, allowing users to send a property directly or to “chat” via instant messaging with agents. For example, a wife would be able to send her husband property details without having to resort to email. Someone who had seen a property of potential interest could directly message the agent to ask for more details or to arrange a viewing.

Charlotte-Ann Swerling, chief operating officer of Sketch Innovation, the company behind the Patch app, said it has some high-profile backers, including Rupert Hambro and Mark Swire of Swire Property.

The launch of Patch follows that of OnTheMarket which Swerling said was a very different proposition.

She said of OTM: “It is of course focused on better economics for underlying estate agents but offers nothing new to the consumer.

“Indeed, arguably it offers a much worse consumer experience as it has a fraction of the listings of Zoopla or Rightmove, at least for the time being.

“By contrast, we are making no innovations on the estate agent side. So much so that we are not even liaising directly with estate agents or signing them up directly. Our innovations are on the consumer side.

“All our listings are powered by Zoopla so we have launched our app with exactly the same listings as Zoopla, and so the second largest inventory in the market, second only to Rightmove.

“For this reason we are not concerned about OnTheMarket’s only-one-other-portal policy as, in their terms, we do not count as a portal distinct from Zoopla.

“That said, we are not owned by Zoopla, though their help for us can be taken as an indication of the way in which they are promoting consumer innovation in the UK property sector – something we do not see any of the other major players doing.”

She said that Patch has no plans to become a private listings site.

Swerling added: “We are already seeing good traction with consumers despite the fact that we have not started a major marketing push.”
