SKRWT is the best app for straightening out your photographs so they look perfect, not crooked.

What is it about?

SKRWT is a simple app that does one thing: it corrects keystone and lens distortion in your images, so that they don't look so crooked or uneven. The app is super easy to use, with intuitive tools that let you adjust both vertical and horizontal perspective so that the edges and lines in your photographs appear more straight and even. The dials that are used to adjust the amount of adjustment are super precise, so you don't have to worry about it moving around once you remove your finger from the screen. Once you've made all of your necessary adjustments, just save the image or send it off to another app for more editing or sharing with others. It's the best app to help you remove that pesky distortion from the lens.

For those who...

  • Want to remove lens distortion from photographs
  • Want precise control over the adjustment dials

Not for those who...

  • Don't care about straightening out lines in images
  • Don't see a need to remove lens distortion

Why we love it

SKRWT is a simple and intuitive app that makes it easy to remove the crooked lines and lens distortions from your photographs before sharing. Plus, the precise dials mean accurate adjustments, so you don't have to worry about being too careful with the tools.
