Snapseed is a highly regarded photo enhancement app for the iPhone and iPad (4.5 stars average customer ratings with 393 ratings) that normally costs $4.99. However, if you visit Apple’s App Store between now and Saturday, you get can it for free.

Snapseed (iTunes App Store)

Snapseed provides the following photo enhancement features:
- Single tap auto-correct
- Single tap before and after comparison
- Selective Adjust for specific objects or areas in a photo
- Simple to use cropping tool
- Collection of photo filters
- Photo borders
- Support on an iPad 2 for working with RAW photos from a conventional digital camera

Enhancement types are selected using up and down gestures while adjustments for a specific enhancement is done using a side-to-side gesture. All the changes happened instantly on an iPad 2. It is simple to not choose or undo any change.

A tip of the hat to @David_W_Martin of Cult of Mac & BYTE for telling me about this deal.
