ChocoFlop allows you to edit your photos or design stuff using Apple's CoreImage technology. It takes advantage of the power of your graphics card (GPU). Because of this it can show real-time previews of filters and keep modifications live for as long as you want. This means that you can add for example a blur filter on your text and keep everything dynamic. You can change the strength of your blur filter at any time or edit your text, the blur will apply on the updated text. That's called non-destructive image edition and it really saves you a lot of time.
