Anyone with any browser can see your app in motion with AppSurfer

Indian start-up AppSurfer wants Android users to be able to view an app before buying it, regardless of the web browser they are using at the moment. By embedding the app onto a website, blog or social network, any web browser has access to it allowing anyone to see your app working before buying or installing it. Letting potential buyers of an app view it in advance is not completely new as the Amazon Appstore allows for limited trials of certain apps, but there are geographic limitations and you can only access the trial from the Amazon Appstore.

Unlike similar programs, AppSurfer doesn't require you to download any software and those looking to purchase or install an app are directed to the Google Play Store. AppSurfer has been in private beta since March of this year although publishers/developers can sign up for the program at the sourcelink. For developers, it could mean more business from those who are getting to see your app in action.  It has to be a better sales tool than the static screenshot pictures on Google Play Store
