Post Processing on ipad / tablet

Hi guys,

I primarily use lightroom and then photoshop for PP at home, I've recently started playing around with the ipad camera connection kit and Snapseed for post processing on the go - it's been an interesting little experiment and has lots of potential I feel - that said, as fun as Snapseed is - I miss my photoshop curves, and blend / adjustment layers.

Can anyone recommend, or does anyone know of an ipad app that allows for this kind of thing - Snapseed is fun, and has some nice contrast and sharpness options - but I'm not so keen on the clunky film presets and fake texture overlays - and would like more flexibility in adjusting colour and tone.
