Menus/Navigation handlers in mobile

Navigation / Menu handlers are the important element when it comes to the mobile apps and mobile websites.  following is the study i went trough my latest iPhone and I came to a conclusion. here is the un standardized navigation handler among the apps.

Most of the Websites follows the right side menu handler, including the Twitter bootsreap.

Starbucks Website's responsive navigation handler is in the right side

Microsoft's Website's responsive navigation handler is in the right side

But when it comes to the Apps, almost every app’s are following the left side menu handler.

Path App's navigation handler is in the left

Google+ iPhone App's navigation handler is in the left

FourSquare iPhone App's navigation handler is in the left

Vine iPhone App's navigation handler is in the left

Nike+ iPhone App's navigation handler is in the left

Unfortunately, some apps are yet follows the righthand side menu handlers.

Apple iOS's Music app's navigation handler is in the right

Nike+ iPhone App's navigation handler is in the left

As a right hand phone user, I aways prefer the menu handler in the right side, but comparatively within the apps, there is no consistency, hence i prefer the Apple should allow the users to customize the menu handlers position according to the users wish. where as the websites, it is a bit  complication. but still web designers can make a decision based on the UX testing and user testing in the labs and anonymous data tracking with some tools like google analytics. Specially when they are designing for the targeted audience, it will be more simpler.
