The iPhone Duo represents the biggest change to the iPhone's form factor in its nearly 20-year history. This compact, notebook-style device features an iPad-like inner display. While the design may look awkward initially, the weight distribution makes it more comfortable to hold than the iPhone 18 Pro Max despite weighing 254 grams.
The device measures 11.3mm thick when closed and unfolds to just 5.2mm, thinner than the iPhone Air. Its 7.6-inch display offers significant pocketability benefits with a shorter, wider footprint. The innovative hinge system features over 100 components with variable torque resistance and integrated magnets.
However, extended one-handed use still causes wrist fatigue. The review unit was sponsored by Craft, a productivity app now optimized for the iPhone Duo from day one, offering 40% off with code 9to5Mac40.
