SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Profiling and optimizing mobile apps to eliminate jank, reduce startup time, fix memory leaks, shrink bundle size, and sustain 60 FPS on every screen. Use when the app feels slow, frame drops occur, or battery drain is noticeable.

Core Features & Use Cases

  • End-to-end performance auditing across React Native, Flutter, and native iOS/Android.
  • Phase-based optimization workflow with measurable before/after improvements.
  • Use Case: Improve a mid-tier app's cold start from several seconds to under 2 seconds or stabilize 60 FPS during heavy scrolling.

Quick Start

Run a real-device profiling session following the mobile-perf workflow to identify bottlenecks and implement phased fixes.

FAQPage Schema
How do I profile and optimize mobile app performance to eliminate jank and reduce startup time?

To profile and optimize mobile app performance, you need real-device profiling data and a baseline measurement to identify bottlenecks, followed by a phased workflow using platform-specific tooling to measure before and after improvements.

What's the best way to fix memory leaks and reduce battery drain in React Native and Flutter?

Fixing memory leaks and reducing battery drain requires an end-to-end performance audit across React Native, Flutter, or native iOS/Android, utilizing real-device profiling to isolate memory usage and battery impact issues.

Does this mobile performance optimization workflow support both native iOS and Android apps?

Yes, the mobile performance optimization workflow is applicable across native iOS and Android apps, as well as React Native and Flutter, covering frame rendering, memory usage, and battery impact profiling.

How do I sustain 60 FPS during heavy scrolling in a mobile app?

To sustain 60 FPS during heavy scrolling, run a real-device profiling session to identify frame rendering bottlenecks, then implement phased fixes to stabilize the frame rate and eliminate jank.

Can I reduce cold start time for a mid-tier mobile app to under 2 seconds?

Yes, you can reduce cold start time to under 2 seconds by profiling the app's startup phase on a real device, establishing a baseline measurement, and applying a phased optimization workflow to target specific bottlenecks.

Why do I need baseline measurements before optimizing mobile app performance?

Baseline measurements are required for mobile app performance optimization because the phased workflow relies on comparing before and after improvements to verify that frame drops, startup delays, and battery drain are effectively resolved.
