Mobile app performance directly impacts user retention. Studies show that 53% of users abandon apps that take longer than 3 seconds to load. Here are the strategies we use at PixelsBD to keep our apps blazing fast.
Lazy Load Everything
Don't load screens, images, or data until the user needs them. Both React Native and Flutter support lazy loading patterns out of the box.
Optimize Image Assets
Use WebP format, implement responsive sizing, and cache aggressively. A single unoptimized hero image can add 2-3 seconds to your load time.
Use Native Animations
Animated API with useNativeDriver: true runs animations on the UI thread, maintaining 60fps even during JS-heavy operations. Following these practices, our apps consistently achieve startup times under 2 seconds.
