Do you get stressed by crooked photos? Do you obsessively try to straighten them with editing tools? Obsess no more!

OCD Zoom is a camera app that detects rectangular objects and automatically zooms, straightens, and un-distorts them.

It's ideal for taking pictures of paintings, computer screens, book covers, and ... doors I guess. It can also scan documents, although specialist apps like Google Drive and Dropbox usually do a better job.

OCD Zoom is a freemium app. It adds a faint watermark to the photo, which you can remove by throwing some coins in the tip jar.
