Why is Duolingo App So Slow?

Slow Duolingo app issues are usually caused by:

  • Outdated App Version: Running an outdated version can lead to performance glitches.
  • App cache issues: Accumulated cache can slow down the app’s responsiveness.
  • Network Connectivity: Poor internet connectivity can hamper the app’s loading speed.
  • Device Storage: Insufficient storage on your device can impact app performance.
  • Background app activity: If you have a lot of other apps running in the background, this can take up valuable resources and slow down Duolingo.

How To Fix a Slow Duolingo?

Here are the best solutions for how to fix a slow Duolingo.

1. Check if Duolingo’s down. The Duolingo service could be experiencing a server outage or other technical issues. If Duolingo is experiencing downtime, you’ll just have to wait for Duolingo to resolve the issue. 

2. Check your internet connection. The quickest way to do this is to open another app or website that needs an internet connection.

If Wi-Fi is slow or down, switch to cellular. If cellular is slow or down, switch to Wi-Fi. The process of switching between Wi-Fi and Cellular connection depends on your platform: Android, or iPhone.

You can also toggle Airplane Mode on and off (AndroidiPhone)

3. Close background apps: Close any apps that you’re not using, including games, music players, and social media apps. This will free up resources for the Duolingo app.

On iPhone, Swipe up from the bottom of the screen, swipe left to find the app you want to close, then swipe it up and off the top of the screen.

On Android, Go to Settings Apps, select an app you want to stop, and then tap Force Stop.

4. Restart the Duolingo app. Properly closing the Duolingo app, not just minimizing it, and then opening it again could fix the slow loading problem. (AndroidiPhone)

5. Restart your device. Restarting your mobile device will often clear most problems. So take a moment to reboot your Android or reboot your iOS device to see if it resolves lagging problems with the Duolingo app.

6. Check for Duolingo app updates. Check for and install any Duolingo app updates on your Android device or app updates on your iPhone.

7. Clear the Duolingo app cache on your Android device or clear the cache on an iPhone. This can sometimes resolve Duolingo app lagging issues caused by corrupted or outdated app data.

8. Uninstall and reinstall the Duolingo app. If nothing else has worked to this point, take the time to completely uninstall Duolingo from your Android or iPhone. Then reinstall the Duolingo app on your device.

9. Free up space on your phone. A lack of free space can often cause apps to load slow. The process of freeing up storage space depends on your platform: Android, or iPhone.

10. Try using the Duolingo website instead of the app: The Duolingo website may be less resource-intensive than the app, and it may run more smoothly on your device.

11. Check Page Speed of the Duolingo page you are accessing on the Google PageSpeed Insights website. If the page speed is low due to bloated JavaScript files, unused CSS files, render-blocking resources, large DOM size, or an ineffective caching policy, then developers at Duolingo need to fix it.

12. Report the issue to Duolingo. It could be an issue with your account, and Duolingo customer support should be able to help you determine if that’s the case.


How do I make the Duolingo app faster?

To enhance the speed of your Duolingo app, consider updating the app regularly, clearing the cache, optimizing your device’s performance, and checking your internet connection.
