TTI Measurement Scenarios Analysis

Implementation Note

appOpenedTime always uses mainActivityStartTime: The difference between appStartedTimestamp (process creation) and mainActivityStartTime (MainActivity creation) is negligible (20-40ms). Using mainActivityStartTime consistently simplifies the code and fixes edge cases where the conditional logic couldn't distinguish between different launch scenarios (9c, 9f).

Reduced Motion + React-Freeze Bug Analysis

Problem Summary

Issue: Gray screen appears on Android when users enable "Reduce Motion" accessibility setting and quickly swipe between channels.

Root Cause: Animation updates (translateX) arrive while components are frozen/unregistered, causing updates to be lost and components to render with stale values.

Context: I've been working on this issue and there are currently three different solutions in play. I want to present the situation to the team and get alignment on the best approach.

React Freeze Performance Analysis Report

Executive Summary

This comprehensive performance analysis compares react-freeze against custom freeze implementations and a no-optimization baseline. The results demonstrate that react-freeze provides superior performance across all metrics, with 8x faster frozen rendering and 3.6x fewer total renders compared to no optimization.

React Native Reanimated Microtask Bug

Reanimated Animations Stalling?

How Szymon and I traced it to an Infinite Loop & Fixed It

tl;dr – A tiny helper (infiniteThenable) inside react-freeze made React’s Fabric scheduler loop forever, so the JS → UI microtask bridge never got a chance to flush. We patched the scheduler to flush manually and replaced the culprit with React 19’s Offscreen – animations are smooth again.

1. The Symptoms

  • Animations powered by Reanimated randomly froze.
