The comparison view is a text list in a top/bottom format. It is not a side-by-side view of the two PDFs themselves. Scrolling the list view is sluggish.This app is not unusable to review for the exact locations of editing changes made in a PDF from one version to another, e.g. when generating a revision to a manuscript. This app may be useful simply to determine whether one copy of a PDF is different from another, and in what ways.
Very useful, I hope it can support shortcut commands
ZiYan.5
Good exquisite software, recommendations, and several suggestions:① I hope to support shortcut command operations to greatly improve efficiency ② I hope to add text similar to the final shared, and add it as an option to the results to display. Thanks to the author
A subscription fee? Really?
Fairlyodd125
I’m sorry, but a subscription fee for an app, that is self-proclaimed to be completely offline and on-device (which is good), is just greedy (and unethical) on the developer’s part. If the app is running 100% on-device, there are no infrastructure costs to maintain that could even remotely justify a subscription fee. Subscription culture is out of control.
It just flashes and does nothing
Reviews 325
Expensive little app that flashes and then closes itself out
Built for iPhone Duo
• On the inner display, side-by-side comparisons keep each document on its own side of the fold, so no line runs across the crease.
• In landscape, the two document panels now sit next to each other instead of stacked — on iPhone Duo's outer display and on every iPhone.
• Onboarding adapts to landscape, and its text scrolls instead of getting cut off.
