-- Local iOS Simulator video over browser-native WebRTC H.264 with VideoToolbox hardware encode and x264 software encode
-- Android emulator frames are sourced from emulator gRPC; loopback browsers use raw RGBA over WebRTC, and non-loopback browsers use VideoToolbox-encoded H.264
+- Supports streaming both iOS simulators and Android emulators
 - Full simulator control & inspection using private iOS accessibility APIs and Android UIAutomator - available using `simdeck` CLI
 - Real-time screen `describe` command using accessibility view tree - available in token-efficient format for agents
-- Simulator app performance gauges for CPU, memory, disk writes, network throughput, hang signals, and stack sampling
+- Profiling built-in: CPU, memory, disk writes, network throughput, hang signals, and stack sampling
 - CoreSimulator chrome asset rendering for device bezels
 - NativeScript, React Native, Flutter, UIKit and SwiftUI runtime inspector plugins to debug app's view hierarchy live
 - `simdeck/test` for fast JS-based app tests that can query accessibility state and drive simulator controls
