PDF Expert, the powerful PDF viewing and editing application from Readdle, got a big update today that features few new features and tweaks to make it even more useful along with a big speed boost.
The big news, though, is that PDF Expert is a universal app for the first time. Where previous versions were device-specific for the iPhone and iPad, PDF Expert 5.1 brings both interfaces together in one app. To accommodate the change, the old iPhone version has been retired. Version 5.1, which was formerly iPad-only, will now work on the iPhone as well, with all features supported across both devices.
