SuperPhoto Free is a photo editing app for your Windows Phone 8 or 7.x device that boasts to have hundreds of awesome effects.
Admittedly, SuperPhoto Free does have a healthy selection of filters, effects and other photo editing effects. The app's secret? None of the effects are stored on your Windows Phone. Instead, the effects are downloaded to your Windows Phone when selected.
This system not only gives you a large selection of photo editing tools but also keeps the from taking up too much storage space. Minimizing the need for on-board storage is SuperPhoto Free's strength but beyond that, the app is a little cumbersome.
