Launch Time

The U.S Bank iOS app took 3.788 seconds to launch.

Loading Time — Home Equity Loans Page

It took 26.6 seconds for the Home Equity Loans page to load. Below is a screenshot of some of the API calls that took place to U.S Bank hosts:

There were a considerable amount of calls made to the U.S Bank API to load this page. The slowest calls took 3.13 seconds, 2.82 seconds, and 2.74 seconds to receive a response. The endpoints for those calls are highlighted below:
3.13 Sec Endpoint 1
2.82 Sec Endpoint 2
2.74 Sec Endpoint 3

The screenshot on the top shows some of the third party API calls made to load the Home Equity Loans page. The Waterfall UI allows you to see every call made during the session.

HEADSPIN RECOMMENDATION: Try and reduce the number of calls being made to load this piece of content. If possible, consider reducing the number of 3rd parties integrated into the app to improve performance. Another thing to consider is looking into the server-side work being performed by the US Bank hosts. This can help speed up how fast those servers fulfill requests.

Optimizing Connection Reuse

This table contains some of the instances of new connections created instead of reusing existing ones. In total, your app created 59 new connections unnecessarily.
HEADSPIN RECOMMENDATIONConsider organizing your connections into a few large buckets, versus many small buckets. Since every connection to your server keeps the device radio on, it’s crucial to minimize the connections that occur to preserve the battery consumption and cellular data used.
HTTP Redirects
This is a snapshot of the HTTP Redirects your app encountered. There were 43 HTTP Redirects in your app, leading to an impact time to the user of 4.236 seconds.
HEADSPIN RECOMMENDATIONMake sure your app is looking in the right places for resources. HTTP Redirects create unnecessary delays in your app.
