HoverBar Duo is an adjustable arm that lets you extend the use of your iPad. At your desk, you can use the HoverBar Duo as a desktop stand next to your Mac with SideCar to keep track of your calendar, view your stock, or use hands-free FaceTime calling. Attach the clamp to the HoverBar Duo and attach it to the ledge of your desk, tables, or your kitchen cabinets - you'll always have your iPad at the height you want so you can recreate a recipe.
