Apple's first foldable phone, due later this year, might not be called iPhone Fold, despite most reports calling it so.

Instead, it will be called iPhone Ultra, and it will join Apple's "Ultra" lineup of devices which includes the (existing) Apple Watch Ultra, as well as the upcoming MacBook Ultra.

This is according to Macworld, whose report cites a source familiar with Apple's plans.

The Ultra moniker will signify, in simple terms, the best of the best, and Apple reportedly plans to market the foldable iPhone as a higher-end model than the Pro iPhones. The report claims that Apple will introduce the iPhone Ultra alongside the Pro models in September, but it may arrive "a few weeks later and in smaller quantities."

We heard about the Ultra moniker in March. Bloomberg's report at the time, however, said Apple may not go with the Ultra name for its foldable phone.

This new report claims that Apple will also bring the "Ultra" branding to the Mac, though details about that device are scarce. Bloomberg said Apple might bestow the name upon its long-rumored touchscreen MacBook, though an "Ultra" iMac also isn't out of the question.

Apple already calls several of its products "Ultra," including the Apple Watch Ultra, the M1 Ultra chip, and the CarPlay Ultra. The criteria on what gets to be called Ultra seem a bit arbitrary, but it always designates the most powerful product in the company's lineup.
