{"appstoreID":6798298905,"title":"RocketTrace for Xcode","subtitle":"App Performance Profiler","developerName":"SwiftLee","description":"Find the performance work that matters.\n\nRocketTrace turns dense Xcode Instruments recordings into a focused, ranked list of evidence-based findings. See measured impact first, inspect the supporting trace evidence, and carry each opportunity into your coding workflow with a self-contained investigation prompt.\n\nFEWER TOKENS, MORE FINDINGS\nIn our published benchmark, two leading AI coding models investigated the same Instruments recording, which contained 20 planted performance issues. With RocketTrace they used about 6x fewer tokens, finished about 2x sooner (including RocketTrace's import and analysis time), and found 7 to 8 more of the 20 issues than with raw Instruments exports. One recording, one app, three runs per model: your results will vary. Method and limits: https://rockettrace.app/blog/agent-trace-benchmark/\n\nPROFILE A REPEATABLE SCENARIO\nRecord a supported macOS app from a recent Xcode build, or import a compatible Instruments .trace bundle recorded for a macOS, iOS, or iPadOS app.\n\nFOCUS ON ACTIONABLE EVIDENCE\nRocketTrace analyzes Time Profiler, hangs, animation hitches, Swift Concurrency, and SwiftUI data. Findings include measured duration, frequency, execution context, and representative app-code frames where available.\n\nWORK WITH YOUR CODING AGENT\nCopy an individual finding as an investigation prompt or export structured results for your preferred coding agent. Prompts preserve the evidence and require code-level verification instead of guessing at a fix.\n\nVERIFY THE RESULT\nRecord a comparable candidate trace after making a change. RocketTrace shows before-and-after metric and finding deltas so you can check whether the measured behavior actually improved.\n\nPRIVATE BY DESIGN\nTrace parsing and analysis happen locally on your Mac using your selected Xcode installation. Trace files, symbols, source paths, app names, and investigation prompts are not uploaded or included in product analytics.\n\nRocketTrace requires macOS 26 and Xcode 27 or newer.\n\nCheck out our other app, RocketSim, as well. It enhances the Xcode Simulator with capture, networking, build insights, and quick actions right beside the Simulator.\n\nXcode® is a trademark of Apple Inc., registered in the U.S. and other countries.\nTerms of use: https://rockettrace.app/terms/\nPrivacy Policy: https://rockettrace.app/privacy/","bundleID":"com.swiftlee.RocketTrace","appiconURL":"https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/42/9b/d6/429bd66c-1aa7-1f21-7a7b-4714ef6d2828/Placeholder.mill/1024x1024w.webp","bannerURL":null,"formattedPrice":"Free","appUpdated":"2026-11-06T16:42:18.000Z","appReleased":"2026-09-25T07:00:00.000Z","version":"1.4.0","platforms":["mac"],"minOS":{"mac":"Requires macOS 26.0 or later."},"topIAPs":[{"name":"RocketTrace Pro Yearly","price":"$69.99"},{"name":"RocketTrace Pro Monthly","price":"$8.99"}],"languages":["EN"],"size":"21.9 MB","category":"Developer Tools","developerWebsite":"https://rockettrace.app","screenshots":[{"platform":"mac","url":"https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/04/d0/79/04d079a5-5445-8d4e-bbf5-b7caebcab22f/01_Instruments_vs_RocketTrace.png/2880x1800w.webp"},{"platform":"mac","url":"https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/c0/65/9b/c0659b8c-38c3-1a48-1608-a8b370b93899/02_Key_Signals_Together.png/2880x1800w.webp"},{"platform":"mac","url":"https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/f5/13/5d/f5135d06-e06a-6717-6f48-280dfde45154/03_Agent_Ready_Context.png/2880x1800w.webp"},{"platform":"mac","url":"https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/19/29/60/19296060-22da-2bda-6b24-b7c76bbc356a/04_Profile_Real_Devices.png/2880x1800w.webp"},{"platform":"mac","url":"https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/6f/b3/f2/6fb3f286-ed9e-35bd-74c4-d484a16c2f18/05_SwiftUI_Updates.png/2880x1800w.webp"},{"platform":"mac","url":"https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/20/ce/f5/20cef566-4c7d-b146-f415-1c5977413276/06_Findings_Across_Runs.png/2880x1800w.webp"}]}
