Buggy, incompleted and unsupported

The usability for basic viewing and zooming is fine and comfortable to use, except for the tilting which is a bit annoying for me personally, since I always prefer to look at the chart without prospective view.
Unfortunately, the application comes with numerous bugs (measuring distance wont work, search wont work, etc), and doesnt offer any help or documentation on how those bugged feature were intended to be used at all.

I read also from other users that restore purchased content is not working either.
