USE CASE 1

Monitor your Android app for startup slowdowns and main thread freezes with zero code rewrites

USE CASE 2

Detect native memory leaks in your iOS app and get the exact line of code responsible

USE CASE 3

Analyze your APK size and receive automated suggestions for reducing the download size

USE CASE 4

Track whether your app drains battery by leaving sensors or network connections running in the background

Copy-paste prompts

Prompt 1
I want to add Matrix to my Android app to detect when the main thread gets blocked. Show me the minimal setup code using TraceCanary and how to handle the callback when lag is detected.
Prompt 2
Using the Matrix APK Checker, how do I run a size analysis on my release APK and interpret the output to find which resources or classes are inflating the download size?
Prompt 3
I am integrating Matrix on iOS to catch memory issues. Give me the Swift setup code to enable the memory monitoring plugin and log alerts when high memory usage is detected.
Prompt 4
My Android app drains battery in the background. Walk me through enabling Battery Canary in Matrix and reading the output to identify which component is holding a wake lock or sensor open.
Prompt 5
How do I configure Matrix on Android to enable only Trace Canary and IO Canary, and disable all other plugins?
