App Performance Rates (2024)

Updated: March 25, 2024

App developers have an entire arsenal of marketing and engagement tools to draw in users and retain them, but if the app crashes or uses a large amount of available memory, chances are users won’t stick around very long.

In surveys conducted by Embrace, a high percentage of users consider an app crash, freeze, or even slow startup to be cause for deletion. Over the years, Google and Apple have optimized their mobile experience by reducing the amount of inactive memory used, and providing warnings for smartphone users close to maxing out their available memory.

While Google and Apple have best practices and rigorous review systems to ensure poorly built apps don’t reach the app store, there are dozens of iOS and thousands of different Android hardware iterations. Both app stores also house hundreds of thousands of apps, making it almost impossible to ensure a completely crash free experience for every user.

That said, the vast majority of sessions are crash free and the best developers regularly test the performance of features and run them through crash test services. Other measurables, such as application not responding rates and user termination rates, are also tracked.

We have collected data and statistics on app performance rates. Read on below to find out more.
