Diff Viewer

Easily Compare Two Files

Free · In-App Purchases

This simple diff viewer shows two files side-by-side. Choose from line diff or word diff (premium feature). Merge differences to the opposite file by clicking an arrow button. Remove differences by pressing the X. Drag-n-drop is supported for easy file diffing fun! If a file is changed while you are diffing, an alert will pop up asking if you want to load the changes. This app was originally designed for iOS, but I brought it to Mac too. I hope you like it!

Should be much faster on large files. Lots of bug fixes, including a bug preventing scroll sync between panes -- sorry!
