I would definitively say android. Personally I also would tend to say android would be my personal choice. However due to the fact it's clearly an android site, it could be biased
Anyhow, I would say, the best option is a web site with HTML 5, to have the best cross platform options, or use some tools to transform your site into an app. Mind you, it's my personal opinion.
