Official Description

AndifTouch is an app to interactively correct radial and perspective distortions in pictures. Radial distortions are typical for wide angle photography (e.g. fisheye effect and barrel distortion, in german: Fischaugen Effekt and tonnenförmige Verzeichnung). Perspective distortions (keystone effect, tilt and shift or in german: Stuerzende Linien) occur often in architectural photography.
