Program for 3rd Generation IPad Air

[Barbara224160921ej5]

Is there a program /app available so I can view my Sony7AIV raw files on my iPad Air 3rd generation.  I have the apple lightenings transfer device but never tried it even for my Sony a6500 raw files. 
I would use this only for viewing while traveling to see what I am getting.  Any advice welcome.

That Help page shows which cameras are supported and which version of Lightroom you would need.
