Works AWESOME

I use this app with my iPhone4 and iPhone5 as a chassis diagnosis tool, works great especially with the ability to enable the light/torch.
Only things to add/improve would be;

1) Video capture option.
2) Higher resolution for the remote live preview, (captured pics are great resolution)
3) Manual focus ability.

If the app had these it would be PERFECT and worth twice the price.
