With modern smartphones exceeding 6.5 inches, top navigation bars and hamburger menus are out of comfortable thumb reach for 80% of users. Place core navigation tabs, search triggers, and primary CTA buttons in the bottom 40% of the screen.

Pair swipe-to-dismiss, pull-to-refresh, and drag-and-drop gestures with subtle haptic vibration triggers to reinforce the feeling of physical manipulation on glass.
