What is App Frontend Performance

Mobile App frontend performance ensures a high quality & performant experience every time a user interacts with the app. As per Android & iOS, an app is considered performant if :

1. Launches Quickly: Ensures users can start using the app with minimal wait time.
2. Provides responsive UI: Offers natural and interactive UI interactions with efficient rendering performance.
3. Uses Device Resources Efficiently: Uses minimal device resources such as memory, battery, etc.
4. Is space efficient: Has minimal download & install size.
5. Key user journeys are performant: Ensures key app user flows are streamlined and performant.

For more details, refer to performance guidelines from Android and iOS.

Why it matters

Organisations developing consumer mobile apps, games, or SDKs should improve app frontend performance for the following reasons :

• It directly impacts end user experience and satisfaction. Mobile users are more sensitive to performance compared to the web users.
• It impacts rankings and ratings on app store & play store and therefore, influencing app installation rates.
• It impacts app engagement & retention metrics

App Frontend Performance Testing on BrowserStack

BrowserStack’s App Frontend Performance Testing feature allows app owners and QA teams to easily detect client-side performance issues during testing. It integrates seamlessly with BrowserStack’s existing app testing products App Live & App Automate.

Key Features

• Inspect performance metrics without any app changes: Capture every aspect of app performance that could impact user experience as you naturally navigate through critical user journeys. It captures metrics such as installed-app-size, page load time, slow and frozen frames, and detailed analysis of memory, battery, etc.
  
  

• Generate comprehensive performance reports: For every test session a detailed app performance report is generated. By testing key user journeys, you can automatically capture and collate all performance issues into a single report.

• Interactive debugging to identify performance hotspots : Provides timeline view of metric measurements correlated with detailed video recording to identify performance hotspots in key app workflows.
  
  

• Test performance on real device cloud: Leverage the BrowserStack device cloud with 20,000+ real mobile devices.

• Test performance in real world user conditions Simulate various real user conditions such as network throttling (3G,4G, etc.), geolocation while testing app frontend performance etc.

• Share performance reports Generate public URLs to share performance reports with your team.
