A very powerful iPhoneography app bringing desktop functionality to the iPhone. Vast array of image editing features including curves, colour correction, layers, masking (with gradients) to name just a few. Primarily used by me for cropping, re-sizing and text.

Rating (all versions): 3.5 (1827 ratings).
Rating (current version): 3.5 (12 ratings).
Current Price: USD3.99.
Where there are iPhone and iPad apps, rating data and pricing relate to the iPhone app.

"Filterstorm was designed for the iPad from the beginning, and is a study in limitation and excellence." - App Craver

"While Filterstorm certainly won’t replace your image-optimization workflow on your desktop computer, it can prove useful (and fun) enough that you will want to put it to use for quick adjustments to fine-tune an image you want to share via your iPad. " - Digital Photo Pro
