iOS Universal Photography
AndifTouch is an app to interactively correct radial and perspective distortions in pictures. Radial distortions (e.g. barrel distortion) are typical for wide angle photography. Perspective distortions (keystone effect or in german: Stuerzende Linien) occur often in architectural photography.
