Hello, iPhone Duo! GenFuel now fits your foldable. • Built for iPhone Duo: unfold it and GenFuel opens up into a roomy three-column layout. • Landscape on iPhone: rotate your phone and Pro Max and Plus models show three columns, too. • iPad in portrait now uses three columns as well. • Price and consumption shortcut buttons wrap onto two rows when space is tight. • The mode switcher now sits right under the title. • Fixed: content at the bottom of the screen can now be scrolled above the keyboard while you type. Thanks for using GenFuel — more improvements are on the way!
