Insights and Recommendations

HeadSpin’s proprietary AI technology analyzes and prioritizes the core issues impacting critical user journeys. Using computer vision techniques to quantify blank screens, time to interact, loading time, loading or buffering animations, and content quality, our AI models can automatically diagnose server-side issues whether they arise from infrastructure deployment issues, poor performance, or API errors. For a custom analysis of your app, request a Performance Insight report from HeadSpin. 

HeadSpin Performance Session for ServiceNow Agent App on WiFi, Miami (link)

Launch Time

The launch time for this app was 600 ms.

Loading Animation

The orange bars here represent time that the user spent waiting for loading animations. In this snapshot, the two areas of significant loading time were triggered by API calls made when the user hit “Assign to me” and “Start work”. The calls in question are on the snapshot just before the periods of loading.

Call A took 545 ms to complete.

Call B took 511 ms to complete.

Here the user had to wait 3.92 seconds before they could complete the flow to accept the task.

This call took 443 ms to complete.

HEADSPIN RECOMMENDATION: Consider looking at how much work your servers are performing before fulfilling these requests. Alternatively, you can rework the user design to show elements that load faster at the top and move slower elements below the fold.

HeadSpin Performance Session for Now Mobile App on WiFi, Miami (link)

Launch Time

The launch time for the app was 1.01 seconds.

Loading Animation

The user spent 6.6 seconds waiting to launch the demo. These were the calls that took place during that waiting period. The longest call took 318 ms to complete.

HTTP Errors/Redirects
These snapshots show the 2 HTTP errors and 3 redirects that happened during the session.

HEADSPIN RECOMMENDATION: Make sure your app is looking in the right places for resources to fix these issues.
