iOS App Speed Performance Testing

I need a detail-oriented tester to measure and analyse the speed and overall performance of my mobile app specifically on iPhones and iPads. Your main focus will be how quickly the app launches from a cold and warm start and how smoothly each screen loads once inside.

I expect you to run repeatable benchmarks on several recent iOS devices, capture hard numbers for launch time, frame drops, memory and CPU usage, and spot any stutters or hangs. Please use standard Apple tooling—Xcode Instruments (Time Profiler, Core Animation), XCTest performance cases, and, if you prefer, complementary services such as Firebase Performance Monitoring.

Deliverables
• A concise test plan outlining device models, OS versions, and the exact steps you will run
• Raw performance logs and screen recordings that back up every metric reported
• A summary report highlighting problem areas, potential root causes, and practical optimisation suggestions

The work is complete when I can reproduce your results and see clear, actionable guidance on shaving milliseconds off both launch time and initial screen rendering.
