Will not open any file! Google Drive NOGO. iCloud NOGO. iOS notes nogo. iOS 12.1 on iPhone X. Saturday, 24 November 2018. Create 2 new files in any cloud. New files created on iPhone do not show up. Only the files created on my MacBook show up. Try iOS Notes app. Folder: “On My iPhone” which is local, not on any cloud. Same behavior. File list in this app is not usable. Total waste of time, this app is useless. iDiff View by ROCKETBOX LTD Contact: nick.ager@gmail (dot com)

It's a straightforward text file comparison tool. The files you want to compare have to be on Google Drive, iCloud, or some other cloud service that supports the Document Picker Open method. The comparison seems accurate and easy to read. Minus one star for not being able to send files to the app directly, nor indeed to paste text in. Minus another star for not being able to do any editing. All you can really do is look at your results. If you want to implement changes, you'll need to switch back and forth between this and your editing app.
