Performance Organizer vs DubDub!

Performance Organizer is an all-in-one app quality and release analysis tool for Apple platform developers, helping you catch regressions earlier, triage crashes faster, and make better release decisions with MetricKit Metrics, MetricKit Diagnostics, and Xcode Power & Performance Metrics in one place. Available on iPhone, iPad, and Apple Vision Pro. Designed for Apple platform developers, it helps you compare apps, versions, and builds, keep your workspace focused, and quickly see what changed so you can continuously improve app quality and make better release decisions over time. MetricKit Metrics • Analyze MetricKit Metrics across CPU, memory, display, GPU, network transfer, location activity, cellular condition, application time, application exits, disk I/O, disk space usage, launch, responsiveness, animation, and signposts. • Compare metrics by app and version to spot regressions and validate performance improvements. • Track launch performance, responsiveness, animation hitches, and signposts to catch issues before they affect more users. • Review application exit data to understand crashes, watchdog terminations, jetsam, and user-initiated exits. MetricKit Diagnostics • Investigate MetricKit Diagnostics with readable views instead of digging through raw payloads. • Review crash diagnostics, CPU exceptions, app launch diagnostics, hang diagnostics, and disk write exceptions. • Use diagnostics with app and version context to identify affected releases, monitor recurring issues, and guide the next quality improvement. Xcode Power & Performance Metrics • Visualize Xcode Power & Performance Metrics from App Store Connect alongside your MetricKit workflow. • Review Xcode Power & Performance Metrics at the app, version, or build level. • Analyze launch, hang, memory, disk, battery, animation, and termination categories to validate changes and catch release regressions earlier. App Store Connect Workflows • Sync App Store Connect apps, App Store versions, prerelease versions, and builds to keep analysis aligned with your release pipeline. • Review TestFlight beta feedback, including crash submissions and screenshot submissions, in one place. • Filter TestFlight feedback by prerelease version to speed up QA and release triage. Access and Permissions • Support team workflows with App Store Connect API keys while following the Principle of Least Privilege. • Share scoped access so teammates can review performance, TestFlight feedback, and release context without full App Store Connect access. • Use a shared API key for scoped team access, or an individual key to work with everything allowed by your App Store Connect role. Xcode Cloud • View Xcode Cloud integrations for your apps. • Browse available Xcode and macOS versions to confirm build environment context. • Review workflows, builds, and artifacts, and download artifacts to speed up investigation, release review, and follow-up. Subscriptions • Subscriptions unlock advanced App Store Connect workflows for team review and release operations, including TestFlight beta feedback, Xcode Power & Performance Metrics, and Xcode Cloud features. Privacy by Design • Performance Organizer is a privacy-preserving performance and stability tool for Apple platform developers, built around MetricKit and App Store Connect workflows, instrumented with MetricKit in its own development, and designed not to collect private or sensitive customer data from your users.
