Mobile Application Development: How to improve app’s stability and avoid crashing?

App crashing can be one of the main reasons which cause user to abandon the app, leading to low retention rate and failure of the entire project. Even the biggest and most well-known app can crash due to numerous reasons. In addition to app crashing, app instability is also a factor contributing to the growing number of uninstalls. Ensuring your app’s up and running 24/7 is considered as one of the major priorities for any mobile app development company.


To prevent repeated app crashing, it is important that your app can consistently provide seamless experience to the users. There are a certain of things you and your team can do to ensure your app’s stability. In this article, we outline some of the most important measures that will help your business stay on track. Here are the important points which mobile developers and other related parties involved should carefully consider when developing app:

Listen to users’ feedback and fix the errors.

Your app could be released to market without going through extensive testing and users are provided with an incomplete product leading unpleasant app experience. This could be due to last minutes rushing and other reasons. To retain users while ensuring high-level user experience and keeping them coming back using your app, you must try to do more than just acknowledging the errors and crashes. Ideally, your team should immediately identify and fix all the errors reported by users to avoid high rate of app abandonment.

When developers monitor IIS (Internet Information Server) performance, they should also look for other potential bugs and errors. While doing so, they might as well come across other ones and have a fix in place for such errors.

Additionally, when errors occurred randomly due to unexpected app behavior, your team of developers and testers need to use app monitoring tools to identify the behavior that lead to app crashes so you can fix them.  

Test your app on a low-end device

It’s typical that your targeted audiences will install the app on an average low-end device instead of a new high-specs device. If your app is only developed and tested on a number of new devices, it’s very likely that your app won’t be fully compatible and/or not perform as intended on the old devices.

Therefore, it’s a good idea to develop and make your app compatible with a wide range of devices to make sure, it can perform well with any typical mobile device used by your target user. Another benefits of making your app compatible with many devices is that: the more devices your app can serve, the more users you can reach out to and make your app becomes more recognized.

Of course, it is not possible to test your app on all phone and tablet and each user’s device is completely different from one another (different available memory size, hardware specs, aged etc.). Employing external mobile app testing/QA service will help to ensure your app is compatible across different devices, avoid potential bugs and errors leading to app instability and crashing.

Improve user experience and device’s memory management

Pleasant user experience is one of the most important factor that helps retain your app’s user. It makes them stay and continue to use your app. Prompt response and quick feedback are critical to ensure your app’s stability. To maintain high-level of consistency in your app’s UI, your team of developers should try to move heavy processing tasks (e.g. file system accessing, network data loading etc.) to the background threads. The key is to create a balance and while at the same time still ensuring consistent UI experience.

Besides, insufficient memory is one of the main reasons which cause app instability and crashing. This is because each user’s device is different and many of your app’s targeted users still not yet upgrade their devices to a high-end mobile or tablet. Thus, developers should try to account for this factor when developing app.

Check if the app remains functional in poor networks

Many apps need stable and fast internet connection to run. Thus, end-users need access to strong internet connection to use such app. This include social media, game, streaming apps etc. Under the condition of poor connections, users may find the app to be unstable and consequently leads to app crashing. Again, such poor and frustrating app experience will cause users to abandon and uninstall your app.

Usually, app testers and QA test mobile apps on stable internet connections from Wi-Fi networks, while users’ connection can be from mobile data or public Wi-Fi network which might be slow and unstable. Therefore, it is essential that developers test your app in slow connection to find out all the potential problems related to network quality so that your app will perform normally when run under various types of network conditions.


App testing and optimization is essential to ensure your app’s stable performance and consequently the success of your project.
