When we first reviewed Picfx, it was a quirky little square format photo app with a fairly straightforward number of filter effects. It’s grown into a pretty versatile square format photo effects app with a large number of filter presets, adjustments and other new tools that make it worth a look for square format iPhoneography.

The new update has just been released and adds a number of new effects, a new icon, and a capital “P”. The app is no longer called picfx.

The big new addition to this update are the 22 new effects. They range from obscurely named “Ocean” and “Marshmallow” to the more descriptive “Bokeh 6” and “Lomo.” All of the new filters are marked as such until you use them for the first time — a nice touch.

The interface of Picfx is easy to use. Filters are organized by style. One of its great features is that you can stack effects, which basically allow you to create an endless number of effects with the app. A sliding control lets you adjust the intensity of each effect. There’s even a few “premixed” settings already made to get you started.

The interface and usability of the app have improved since the first version. With a tap or two, you can easily add quick, colorful effects to your image before sharing, saving or exporting straight to Instagram, Photogene, or several other photo apps for further processing without first saving to your camera roll.

The app supports almost full resolution on an iPhone 4S — definitely high enough for most needs. It never has. There are no frames or borders. Those need to be added in other apps, if desired. There’s no way to save your own presets if you create a filter stack that you really like. That would make a great addition in a future update.

Especially with the new filters in the the new version 4 update, Picfx is a good, easy to use, square format filter app. It’s also worth a look as a versatile and fairly fast front end for Instagram. It’s one of few good photo apps that still run on just about any iPhone.

Picfx is $1.99. Requirements: Compatible with iPhone, iPod touch, and iPad.Requires iOS 3.2.2 or later.
