Duet Display, an app that turns an iOS device into a secondary display for Mac or Windows systems, has been updated with support for the MacBook Pro's Touch Bar interface -- even on MacBooks that don't have a Touch Bar.

Instead Duet Display simply taps into the appropriate code and models a "virtual" Touch Bar on a connected iPad. As with a real Touch Bar, the simulated one adapts to the active Mac app, for example showing a scrub bar and other playback controls for iTunes.
In the case of apps that haven't been updated for the Touch Bar, Duet should show generic commands.
Taking advantage of Duet's Touch Bar feature requires macOS 10.12.2, as well updated Mac and iOS clients. The latter currently costs $9.99, and runs on any device with iOS 8 or later. Pricing will soon go up to $19.99.
Other iPad-related enhancements include iOS keyboard compatibility, and better handling of the Apple Pencil's pressure sensitivity.
