Accessibility Inspector vs Arm Performance Studio

Accessibility Inspector is Apple’s free macOS tool for examining accessibility information in app interfaces. It displays an element’s accessibility properties, available actions, and position in the view hierarchy. Audits identify common issues such as insufficient contrast, clipped text, and missing descriptions. Results can be saved as HTML reports containing summaries, screenshots, issue descriptions, and fix suggestions. Accessibility audits can also run in UI tests through performAccessibilityAudit(for:_:). The target menu includes apps on Mac and selected iOS, iPadOS, watchOS, or tvOS devices. Open it from Xcode through Xcode > Open Developer Tool > Accessibility Inspector. Apple’s listing describes Xcode as Mac-only, requiring macOS 26.2 or later and an Apple M1 chip or later, and labels it Free. Clearing reported issues does not prove complete accessibility; Apple recommends additional checks with assistive apps such as VoiceOver.

Arm Performance Studio is a free profiling suite for applications running on devices with Arm CPUs and GPUs. Streamline records CPU, GPU, and application activity from a device, and Performance Advisor turns those captures into reports highlighting potential problems and optimization advice. Frame Advisor examines API calls and rendering data for a problem frame and provides geometry metrics. Mali Offline Compiler estimates shader and compute-kernel performance across Arm GPUs, including register usage, cycle cost, and stage-specific recommendations. The suite also includes RenderDoc for Arm GPUs, an Arm fork of the graphics API debugger with support for Arm GPU extensions and Android features. Tools can run without a graphical interface in continuous-integration workflows and export machine-readable data for custom reporting; Unity and Godot integrations can add application markers or counters. The product describes profiling Android and Linux applications and lists Android 11 or later for Streamline, Performance Advisor, Frame Advisor, and RenderDoc for Arm GPUs. Graphics profiling supports Mali GPUs from the Mali-T700 series onward, but not Mali-400 or Mali-T600 products. Community support is provided through Arm’s Gaming, Graphics, and VR forum.
