Optimize Mobile App Performance

My current mobile app does everything I need function-wise, yet it feels sluggish in day-to-day use. I want a set of focused, low-risk tweaks that tighten up speed and overall responsiveness without changing the core experience people already enjoy. Here is what I need from you: • Profile the existing build, pinpointing exactly where frames drop, loads stall, or memory spikes. • Recommend and implement concise code or asset-level optimisations that deliver a measurable performance lift. • Provide a short report explaining the bottlenecks you discovered, the fixes applied, and the before-vs-after metrics (launch time, screen transition time, CPU/memory use, etc.). You will have access to the current source, build scripts, and any analytics dashboards I already run. Feel free to use the standard toolchain for profiling—Android Profiler, Xcode Instruments, React Native/Flutter DevTools, or comparable suites—whatever best suits the stack after you inspect it. Acceptance criteria: 1. Noticeable reduction in the slowest interactions on common devices (I’ll supply a target list). 2. No new crashes or feature regressions. 3. Clear, reproducible measurement data showing the improvement. That’s the whole brief—small, tangible improvements that make the app feel faster while keeping all functionality intact.
