Unfortunately, this issue is more common than you’d think. Luckily, with the help of this article, you’ll be able to solve it in no time.

#1 Check Your Internet Connection

Duolingo offers incredible features that allow us to learn new languages wherever we go.

However, if your Wi-Fi network is having issues, Duolingo may run slow.

I know, fixing network issues might seem like a difficult thing to do. But, don’t worry, I’m here to help. Follow these simple steps to get back to your study sessions:

  1. Run an Internet speed test: Enter speedtest.net and check your download and upload speed. Then, compare it with the Internet plan you’re paying for.
  2. Disconnect some devices: If you’re not getting the Internet speed that your ISP (Internet Service Provider) promised, try checking all the devices that are connected to the same network and disconnect the ones you’re not using. This way, you’ll be able to avoid a saturated network.
  3. Check your router: It needs to be away from kitchen appliances and thick walls. Moreover, if your router and modem have a red or orange light, you’ll need to unplug them from their power sources, wait a few minutes, and plug them back in.
  4. Connect to the 5 GHz network: Most modern routers have two networks (2.4 and 5 GHz). By choosing the 5GHz network, Duolingo may run faster. Please note that you’ll need to be near your modem and router to use this network.
  5. Call your ISP: If the steps above didn’t solve the issue, ask your ISP about their Internet plans because you may need to upgrade yours.

Once you’ve tried the tips above, please launch Duolingo again to see if the issue was solved. If it’s still running super slow, chances are you have bugs, outdated software, or a corrupted cache.

Don’t worry, though. Keep reading to learn how to solve these issues.

#2 Unload Your RAM

Having multiple tabs or apps open at the same time can be super convenient, especially when you’re learning a new language while taking notes.

However, your device needs to run multiple processes in the back to allow you to switch between tabs and display the pages.

If you tend to put your device to sleep instead of turning it off or restarting it, these processes will continue to run and fill up your RAM rather quickly.

If your device runs out of RAM, you may experience all sorts of issues, such as a slow app, a frozen screen, and much more.

Your device needs a break too. This is why I recommend unloading your RAM by closing any apps that you’re not using and restarting your device.

Follow these steps to close apps:

iPhone and iPad:

  1. Swipe up from the bottom of the screen and pause in the middle of the screen. If you have an iPhone or iPad with a home button, please double-click it.
  2. Swipe up on all the open tabs.


  1. Open the Settings menu and go to “Apps & Notifications”.
  2. Select the apps that are open and tap on “Force Stop”.

Windows PC:

  1. Open the Task Manager.
  2. Click on the apps and browsers that are running in the background.
  3. Select “End Task”.


  1. Press the Option + Command + Escape keys at the same time.
  2. Click on the apps that are running processes in the back and select “Force Quit”.
  3. Select “Force Quit” again to confirm the process.

Once you’ve completed the steps above, it’s time for us to restart your device.

If you have a computer, please go to the main menu by clicking on the Windows or Apple (Mac) icon and select “Restart”.

If you’re using your phone or tablet to learn a new language, follow these instructions to restart them:


  1. Press and hold either volume button and the side button until the power off slider pops up.
  2. Drag the slider.
  3. Press and hold the right-hand side button of your device until the Apple logo appears.
Restart your iPhone


  1. Press and hold the power button for 5-10 seconds.
  2. Tap on “Restart” or “Power off” to turn off your device.
  3. Press the power button to turn it on again.


  1. Press and hold the top button. If your iPad doesn’t have a home button, please press either volume button and the top button at the same time.
  2. Drag the power off slider and wait 30 seconds.
  3. Press and hold the top button to turn your iPad back on.

Once you’ve restarted your device, please launch Duolingo.

#3 Clear Your Cache

If you read the title and have no idea what “cache” means, keep reading.

Your cache is a hardware or software component where apps, such as Duolingo, store important information (background images, scripts, credentials, and much more).

This way, every time you launch Duolingo, it can load much faster because it can access this data from your cache folder instead of downloading it from its servers.

Sadly, cached data can easily become corrupted and cause multiple issues while trying to learn a new language.

Luckily, these can be easily fixed by clearing your cache. Follow this quick guide to do it:

Please note that clearing your cache won’t delete your streak.


  1. Open the Settings menu and select “Apps”.
  2. Go to “Installed applications” and tap on Duolingo.
  3. Tap on “Storage” and select “Clear cache”.

iPhone and iPad:

  1. Go to the home screen and press and hold the Duolingo icon for 3 seconds.
  2. Tap on “Remove app”.
  3. Go to the App Store and download it again.

If you’re using Duolingo in a browser, you’ll need to clear its cache and cookies too.

#4 Update the App

If Duolingo is still running super slow, there’s a very good chance you missed an update.

You see, updates make your app run smoother by deleting any bugs and glitches that were causing the issue.

If you haven’t updated Duolingo in a while, you won’t be able to get rid of the error.

But, don’t worry. Installing Duolingo’s latest version won’t take more than five minutes. You’ll just need to:

iPhone and iPad:

  1. Open the App Store.
  2. Tap on your profile picture in the top-right corner of your screen.
  3. Scroll down until you find Duolingo. Then, tap on “Update”.


  1. Open the Google Play Store and tap on your profile icon.
  2. Go to “Manage apps & device” and tap on “Manage”.
  3. Search for Duolingo and tap on “Update”.

Windows PC (Windows 11):

  1. Go to the Microsoft Store.
  2. Select “Library” and click on “Get updates”.
  3. Choose “Update all”.

If you’re using Google Chrome or a different browser to learn a new language, you’ll need to update it too.

#5 Check Duolingo’s Servers

If you’ve tried the four fixes above, but Duolingo is still running slow, try checking its servers.

You see, they are in charge of delivering data to its clients over a network. If these are down, Duolingo won’t be able to display the page correctly, and you’ll experience multiple issues while trying to learn a new language, such as a slow app, login difficulties, and much more.

Server downtime may occur due to multiple reasons, such as human errors, bugs, hacking, and software/hardware issues.

But, the good news is that when servers go down, Duolingo’s IT team usually solves the issue in a couple of hours.

To check if the platform’s servers are down, please enter downdetector.com/status/duolingo/ and check the graph. If it’s orange or red, you’ll know that Duolingo is down.

Check Duolingo's servers


Not being able to complete your language lessons because Duolingo is running super slow can be super frustrating.

Luckily, with the help of the 5 fixes above, you’ll be back to your study session in no time.

Remember, the easiest way to solve the issue is by checking your Internet connection and unloading your RAM. Moreover, updating Duolingo and clearing its cache should also do the trick.
