Dwellable, the Seattle upstart led by Urbanspoon co-founder Adam Doppelt; former NBA digital executive Brenda Spoonemore and Snapvine co-founder Nathan Kriege, continues to carve new territory with its mobile applications for vacation rentals.

Today, the company is announcing a new Android app, as well as upgrades to its iOS app. The Android version comes after many months of development at the startup, which is taking on sites like HomeAway with its vacation rental search offering. Kriege led the charge on the Android version.

“We were one of the first to buy the Nexus 7 and we have designed and tested every aspect of the interface to look awesome on both smaller handsets, but especially so on the larger screen and for slightly different use case of the Nexus 7,” said Spoonemore.

Dwellable shows more than 55,000 properties in destinations such as Cape Cod, Colorado, Hawaii, Washington and Oregon. It is one of many new Seattle area upstarts, along with Trover, Glympse and Z2Live, which have taken a “mobile first” approach to business.

It makes some sense when you look at the data. Dwellable says that 58 percent of its visits in the past 90 days came from mobile devices, while mobile travelers viewed four times as many pages as traditional Web users. In fact, the company said that while traffic increased 34 percent in the past 90 days, the mobile traffic is growing faster.

With the new iOS apps, the company said it is taking advantage of the increased screen size with larger images for the iPhone 5. (Editor’s note: Stay tuned to GeekWire later today as we catch up with Seattle area mobile developers, including Dwellable’s Doppelt, to get insights on iOS 6).
