Society management and marketplace apps share painful screens: long feeds, image avatars, maps, and chat. Small mistakes feel like a cheap app.
Most wins came from list virtualization, image sizing, and killing unnecessary re-renders — not from exotic native modules.
Lists and renders
FlashList-style patterns with stable keys and memoized rows cut scroll jank on mid-range Android devices.
Avoid inline functions and anonymous components in hot paths. Measure with why-did-you-render mindset during perf passes.
Images and bundles
Serve appropriately sized images from CDN. Full-resolution uploads in a thumbnail row destroy memory.
Lazy-load infrequent tabs and split navigation stacks so startup stays under budget.
Key takeaways
- 01Profile on real devices — simulators hide jank.
- 02Virtualize long lists and memoize row renders aggressively.
- 03Keep API payloads small; mobile networks punish chatty screens.
