Ah, another iOS image editor review. There are so many available in the App Store, with lots of overlapping functions. Cropping, filters, frames ... one could get lost.
Handy Photo Free has all these features, but it's the unique features that make it worthy of note. First and foremost, the Move Me technology designed into the app gives it an edge on competing photo editors. Take a person or an object and move it elsewhere in the photo frame, and the background fills itself in automatically. Filters can be applied to all or just parts of an image, and there is smart retouching.
Like many image editors that use the freemium app pricing model, you can upgrade to a full version that adds smart 'uncropping', full-resolution saves, more filters and RAW support. The full version is available at the reasonable price of US$1.99.
