Mobile UI Platform Guidelines with AI

Mobile UI conventions differ between iOS and Android. /touch-ui detects platform first, then applies the right rules for touch targets, navigation, gestures, forms.

Mobile UI conventions differ between iOS and Android in ways that matter to users. Touch targets are 44pt on iOS, 48dp on Android. Back navigation is the swipe-from-left on iOS, the back gesture or button on Android. Tab bars sit at the bottom on iOS and Android, but their behavior differs. Gestures, form patterns, and confirmation conventions differ. Generalist tools that ignore the platform produce designs that feel wrong on one or both.

The /touch-ui skill detects the target platform before applying any guidelines. iOS rules for iOS, Material rules for Android, and platform-appropriate rules per surface (settings, lists, modals). The output is the convention guide calibrated to where the UI will actually run.

Tonone's /touch-ui skill detects platform before applying mobile UI guidelines for touch targets, navigation, gestures, and forms.
