SPOT THE DIFFERENCE Free trial; $30.99 kaleidoscopeapp.com This app is almost as important for what it represents as what it does. This is a filecomparison app with a razor-sharp focus, geared towards productivity. On iPad, the app tries to be as proficient as its Mac version, although ends up coming off second-best. Throw a couple of TXT, DOC, HTML or code documents at it, and you can quickly spot differences in a two-up or unified view. The app also supports Split View, which is just as well, given that it lacks the text merge that’s part of the Mac version. With images, everything suddenly feels fiddly. When it comes to folders, import appears to be an issue. Drop a couple of text files into the app and you’re comparing them almost instantly. Open a couple of web archives, and the app appears to seize up. However, the app clearly indicates files that have changed or are unmatched, and double-tapping a file opens it and its twin for comparison.
There’s ambition here, not only regarding the app but also the iPad. Kaleidoscope is also a good iOS 11 citizen, usable and useful. Just be aware of its limitations, and be sure to put it through its paces during the two-week free trial. In all, it’s solid but occasionally flawed.
