The fixed wide angle lens of your smartphone can distort perspective.
The Perspective Correct app offers live view perspective control to control distortion.

The fixed wide angle lens of your smartphone can make it difficult to achieve accurate perspective in your mobile images, particularly when shooting architecture and landscapes.

The Perspective Correct app allows for live view control over perspective, letting you correct for distortion before capture. The app is out today for iPhone and iPad users, available in the Apple App Store for $1.99 USD. No word yet on when it might be ported to other mobile operating systems.

We've had a quick play with the app to practice manipulating scenes before snapping. The selective focus and exposure controls are also very useful, and we look forward to running the app through our own testing.
