save me lot of time

Accidentally started editing 2 versions of same Pages doc. Pages does not have file diff tool. Export files to PDF and compare with this tool. Merged changes manually using visual results from this app, boom! Done! Save me lot of time for 20 bucks. Five star! The end.

Fills a great need. Primative but wonderful.

Does just what is says, which makes it a unique tool. Lets you compare output of apps that you otherwise never could. The comparison shows the deleted and inserted text, side by side, in two different colors, and generates a text version you could copy and paste.

Doesn't do things you might expect. Doesn't save the names of the files you compared, so you have to start over to compare again. Doesn't support Recents in the File menu. Doesn't let you select all the generated text at once (just each different paragraph one at a time). Doesn't let you export generated text. Doesn't let you zoom the view. Doesn't have context (right-click) commands.

Nonetheless, I'm happy to pay the $20, because it does one good thing.

Developer Response ,

Thank you for your feedback. The PDF views have a context menu which allows to zoom among other things. A trackpad gesture can also be used to zoom. The other wishes get on my list for future releases.
