Great mobile UX feels native, predictable, and responsive. These patterns help your app fit users' mental models and keep them engaged.
Respect Platform Conventions
iOS and Android have different navigation patterns (tabs vs. drawer, back behavior, placement of primary actions). Follow each platform's guidelines so users don't have to relearn your app. Use native components where they make sense; custom UI is fine when it adds clear value.
Thumb-Friendly Layouts
Place primary actions and key content in the thumb zone—the lower half of the screen for one-handed use. Keep top areas for branding and secondary info. Bottom tab bars and floating action buttons work because they're reachable without stretching.
Instant Feedback
Every tap and gesture should get immediate feedback: highlights, haptics, or a loading state. If an action takes time, show a skeleton or progress indicator. Never leave the user wondering whether something registered.
Offline and Weak Networks
Design for flaky connectivity. Cache critical content, queue actions when offline, and sync when back online. Clear messaging ("You're offline—changes will sync when connected") builds trust and reduces frustration.
