iPad Dual screen app for iPad1?

[Freeks]

I'm trying to find app that allows me to use iPad1 as second screen. There used to be few like Air Display, but it seems that all support now +iOS7.

Any ideas?

I also have iPhone 6+, but to use iPhone as screen for what i need for it. It should work as vertical screen, but all apps support only horizontal view.

Doubt any API exists on 5.1.1 that would allow for that.

There WAS apps that supported 5.1.1. I asked from Air Support for older version, but they can't sell it to me unless i have purchased the old version first. It's really stupid that Apple has all those old versions that work with older OS's on their servers, but you can't buy them!

Perhaps it's mainly or at least also up to the developer?
