Ratings and Reviews
An elegant UI wich could use some additional functionality
It's a nice looking app. When the built-in comparison settings apply it's absolutely elegant to use. Additional download from the website offers a ksdiff command line utility which is awesome for whipping up some ad hoc integrations.
When the built-in comparison settings stop applying there is very little configurability in the product. Still no functionality to ignore white-space/line endings in compared text files for example which is a fairly ridiculous omission at this price point. No customization for any of the comparison algorithms at all as a matter of fact which sadly renders the product highly unsuited to most non-trivial problem domains.
Great Idea but not optimized to actually work.
I love the idea of this app and UI/UX design but sadly the app crashes too often & everytime you press copy and try to actually run the task.
So I now just use it as a visual checker and manually transfer on Finder which then it really makes this app not worth the money. I’m still willing to wait and give it a chance but you MUST work on the backend to fix these crashes and review the crash reports plz.
One thing i would like added is a progress bar or a Que to see that status of individual tasks or all tasks. PLEASE fix the crashing issues.
Working on an iMac Pro just FYI if that helps.
Ideas from developer.
At the right pane I see the old file name (before renaming) but the file has a new name.
Bad visualization of differences on scroll pane - light gray color on light background - should be colored.
On the left pane which contain list of files all directory titles is so small - add more font size and/or make color darker.
Please, add color manager for differences - my eyes want to cry!
With Family Sharing set up, up to six family members can use this app.
