Straighten is an upgraded version of an existing software title called goHorizontal and has been developed from a scratch. Straighten lets you correct the overall balance of a picture by rotating it, yet holding on to the same number of pixels. Use two markers in a way such that the line between the end of one marker to the end of the other would be straight.  


  1. Place two markers so that the application can calculate the angle between them.
  2. Zoom in/out on the source picture and the finished picture.
  3. Use horizontal lines to see if the current picture requires further rotation.
  4. Select one of seven line colors.
  5. Select one of three different colors for each marker.
  6. The application support the fullScreen mode.
  7. The application supports the retina screen. (tested with 2014 2.6 GHz 13″ MacBook Pro)
  8. Languages: English and Japanese only.
  9. Application file size: 23.3 MB.
  10. The application comes with a 11-page introduction window, giving the user a quick tour over how it works.

  1. Regardless of original resolutions, the finished picture will be saved to a disk with resolutions of 72 dpi x 72 dpi for non-retina screen models (144 dpi x 144 dpi for retina screen models with JPEG, PNG, TIFF).
