Is your app too slow?

According to a new report, an app should load within less than two seconds on a user’s phone. And the faster your app loads, the better. Users expect punchy, speedy experiences, and research shows it’s now possible to increase engagement by 5% by cutting your app loading time by just one second.

There’s more data to back that up. According to Google, users will abandon an app if it takes three seconds or longer to load, and 80% of users will leave and uninstall an app if it crashes or fails to load.

Simply put, you’ve only got one chance to make an excellent impression—and speed matters.

Below, we’ve put together some strategies for boosting your app’s performance and keeping users happy.

What is mobile app performance? 

Mobile app performance typically refers to its technical efficiency – how it operates under varying conditions. But there are other metrics to consider besides loading speed, such as crash frequency and responsiveness to user behaviour.

Performance can make or break your app’s success. Users quickly abandon apps that fail to deliver a smooth experience, making it crucial to address issues promptly. Proactively improving user experience is not just a good practice; it’s essential if you want to keep users engaged and active.


Measure engagement 

Perhaps the most important way to review your app’s speed is first to understand how it’s being used. Spend some time looking at the metrics or testing your app on your own phone, and you’ll soon find areas for improvement.


Reduce launch delays

Users demand quick access. Optimising startup processes, removing unused code, and asynchronously loading heavy operations can significantly reduce launch times. Users don’t need to see animated logos and explainers. Take advantage of Google and Apple’s APIs and consider low-code and no-code app development if you’re serious about speed and need to deliver an efficient experience.


Consider pre-loaded templates

Efficient use of already loaded templates can greatly enhance app speed. Rather than designing custom frameworks and processes for every screen of your app, reuse the same technologies and design languages. Not only will this impact speed, but it can also make your app feel more familiar and reduce barriers to entry.


Streamline your app

Eliminating non-essential features can boost app performance, focusing on what’s truly important. Do you really need a social media newsfeed pre-loaded in the pull-out menu? Could you find ways to remove unnecessary bloat to make your app file size smaller and more agile? Play around and consider cutting back to give more to your end-users.


Test, test, and test

Testing your app on various devices ensures consistent performance, addressing potential device-specific issues. You could even consider things such as Heat Map Analytics, allowing you to understand user interaction bottlenecks and resolve UI issues, and Funnel Analysis, to measure conversions across different user segments. If you know speed is an issue, the only way to fix it is to delve into your app’s code, make some severe tweaks and improvements, and then perform tests.


Performance metrics to track

Effective monitoring of your app’s speed and performance involves several categories of metrics, such as:

  • Downloads, installs, retention rates, and crashes.
  • User activity levels, session lengths, and churn rates.
  • Financial indicators like ROI and customer lifetime value.
  • Load times, device types, OS, carrier, and API latency.
