In a competitive app market, users have no patience with app crashes. In fact, crashes are the leading cause of app uninstalls. Why stick with an app that has problems when there are thousands of better alternatives? 

Let's begin by identifying some common symptoms of app errors and crashes:  

• black screen
• freezing 
• empty screen
• slow response to user input
• non-responsiveness 
• unexpected restarting 

When your app crashes, you want to know about it. And even more importantly, there are some crucial questions that need to be answered:

• Why did the app suddenly close?
• Where did the error occur in the code?
• What is the path that users took when the crash occurred?
• Can the error be reproduced by following these same actions?
• What device and OS was the app running on? 
• How many users were affected by this same type of crash? 

Error and crash reporting tools provide answers to these questions.

What Are Error and Crash Reporting Tools? 

Error and crash reporting tools help identify and diagnose the root cause of a crash so you can find the right solution for it. The problems can be simple or complex.  

Error and crash reporting tools:

• gather crash data on devices that are running your app 
• generate crash reports that describe what went wrong and identify the possible cause of crashes
• identify the environment or device where the crash occurred

Think of crash reports as evidence that points to the exact place where the app crash happened. They show patterns that help you identify or trace the path taken by the user when the app crashed so you can reproduce the crash and resolve the problems. 

The causes of a crash can be in the foreground or background. 

Some typical causes of crashes in iOS include:

• Swift runtime error
• missing frameworks
• memory access issues

Some common causes of crashes on Android apps include: 

• null values or empty strings
• invalid arguments to an API
• complex multithreaded interactions 

As you have no doubt experienced in your development career, some of these causes can be very subtle and hard to uncover. 

Benefits of Error and Crash Reporting Tools 

An error and crash reporting tool helps you test and identify problems before your app is released. And it helps you monitor the reliability of your app in the wild, in real time.

• keep high ratings for your apps on the App Store or Play Store
• increased user retention rates
• increased user engagement 

With that in mind, let's look at some of the best error and crash reporting tools:
