SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Real-time visibility into app performance, focusing on main thread stalls, frame rate (FPS), CPU and memory usage, delivered via a floating overlay.

Core Features & Use Cases

  • Floating performance overlay for on-device real-time metrics during development.
  • Automated stall detection & stack reporting to help locate bottlenecks.
  • Integration with logging/tracking via xxf-log and xxf-tracker for centralized reporting.

Quick Start

Launch the app in Debug or Internal Testing builds to enable the overlay and begin monitoring metrics in real-time.

Frequently Asked Questions about xxf-performance

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I monitor iOS app FPS and main thread stalls in real-time?▼

You can monitor iOS app FPS and main thread stalls in real-time by integrating a performance monitoring module that displays metrics via a floating overlay during development and internal testing.

What is the best way to detect UI jank and performance bottlenecks on macOS?▼

Detecting UI jank on macOS requires automated stall detection and stack reporting to pinpoint performance bottlenecks across screens, flows, and components using on-device metrics.

How does a floating overlay track CPU and memory usage during development?▼

A floating overlay tracks CPU and memory usage by rendering real-time performance metrics directly on the device, allowing developers to measure frame rates and observe resource consumption.

Can I route iOS stall reports to a centralized logging system?▼

Yes, you can route stall reports to centralized logging and tracking systems by configuring the monitoring module to send performance data to integrated logging or tracking components.

Does the performance overlay support configurable thresholds for frame rate drops?▼

Yes, the performance overlay supports configurable thresholds, allowing developers to define specific limits for frame rate drops and main thread stalls to trigger automated reporting.

When should I enable real-time performance monitoring on my app?▼

Enable real-time performance monitoring during Debug or Internal Testing builds to detect UI jank, measure frame rates, and pinpoint performance bottlenecks without affecting production users.
