It is known that Apps are closed environments and cannot be crawled by search engines and they won’t impact organic search ranking directly.
However, good Apps may work wonder to drive direct traffic to the website. Direct traffic is seen by search engines as an indicator of an authority/brand, which after a while can be translated to higher ranking.
I’d be interested to read webmasters experience about mobile apps and their impact.
