Mobile apps have never been easier to develop.

User wishes have never been easier to implement. Nowadays apps are full of functionalities and have a beautiful user interface, too.

But with new opportunities come new challenges. 90% of users have stopped using an app due to poor performance.

The best way to address performance issues is to use iOS crash reporting tools to find and eliminate them before they affect the user.

Best iOS Crash Reporting Tools to consider


The hardest thing about solving app problems is discovering crashed sessions and getting background about them.

What actions lead to the crash? On which device did it occur?

There is no other tool like UXCam that combines crash logs, crash overview, and session video replays to give you the full context.

On the UXCam dashboard, start with the crashed sessions report. You will now have a list of all the sessions that have crashed.

You can find details about the unit, the location, and the time of the crash.

UXCam works for both iOS, Android, and other frameworks like React Native and Flutter.

To dive deeper, you can click on a session.

Next, to get information on how the crash occurred, you can watch the session video replay.

To open the crash code log, you can press “Crash”.

From stack overflow to out-of-bonds, UXCam monitors all crash forms. It also detects ANR (Application not responding) errors.

To solve crashes easily, you can check and copy the crash log.

You may use UXCam’s Session Analytics Report to get a high-level look of your app’s health. You may go to the crash tab and group the data by app version, device or OS version.

In doing so, you can easily find out whether any issues are caused by a particular app version or device type.

Crashlytics by Firebase offers crash alerts and crash logs for iOS, Android, and Unity.

Firebase Crashlytics presents you with an analysis of the app’s health. When new problems arise or current problems get worse, it sends you a real-time warning.

In addition, Crashlytics provides advice that helps treat common issues.

However, Crashlytics does not send you the full details of issues. You can combine UXCam with Crashlytics. This will build a session replay link within the crash report for Firebase.

What are iOS Crash Reporting Tools?

iOS crash reporting tools should meet these requirements:

1.) Find problems (crashes, ANR errors, bugs) and report them to you.2.) Show the crash log of issues3.) Give background on causes for crashes and errors4.) Have a dashboard where the app’s health can be monitored

Why are iOS Crash Reporting tools important?

The stepwise development of mobile apps takes a major role in software development. Mobile performance tests are performed daily to improve the customer experience and ultimately to increase sales and profits.

However, many product managers have questions about mobile performance testing. Which differences exist between the various performance tests, what metrics are measured, which tools exist, etc.

Common Crash Causes

Bottlenecking: Bottlenecking occurs when the app does not have enough capacity to handle the workload. Common app performance bottlenecks are:

  • CPU Utilization: While apps get more functionalities, pictures, and complexity they need more and more memory and CPU storage. Stress tests will help to find performance difficulties.

  • Network Environment: Thinking that users have a fast internet connection everywhere is a misbelief. Many regions have poor internet coverage. Performance tests should be done under different simulated network conditions.

Poor scalability: This happens when the app can’t handle the number of users, requests or data. Because of this, results could be delayed, errors could increase or the app can behave unexpectedly.

Unoptimized data queries: Each time someone uses the app on an apple device, the database is involved. There might not be a problem as long as the database is small — but when the amount of data grows, unoptimized queries slow the whole system down.

Default Configuration: Every system has its default configurations which help to make new components on the system running.

But they can cause unexpected problems. All configuration parameters must be checked to ensure that they meet the requirements of the goal system.

Not adjustment for real-world scenarios: When designing an app, many scenarios are not considered. Performance tests reveal some of these problems:

  • Performance under heavy load, e.g. when more users as expected use the app at the same time.

  • Unexpected data growth. Many developers plan the system for the first month and don’t think about how much data the database can handle when the number of users and their data grow.

  • The design team thinks about the local performance but not the globally one, where the network coverage possibly is much worse than in the test lab.


Implementing an iOS crash reporting tool requires a thorough analysis and clarification of the targets you want to achieve.

In pursuit of the best solution, we hope that this guide is useful for you.
