Apple is offering users of its Apple Store app free redeem codes to download photo editing app Infltr. Usually $2.99, the acclaimed photo app for iPhone and iPad offers more than 7 million possible filters thanks to a sophisticated color gradient mapping algorithm, and lets users choose a filter before they take a picture or record video.
To get the app, first download the free Apple Store app. The Infltr offer is featured in the Discover section on the main store screen. Offer ends August 15.
Mod: From comments it appears only 16 filters are free, not all 7 million
I deleted it after playing with it for 2 minutes. You only get 16 filters, if you want extra, you have to pay via in app purchase. The included 16 filters are craps too.
