Installing OnStream takes four steps and takes about two minutes

OnStream is a streaming app available through the Amazon Appstore. To install it on your Firestick, you open the Appstore from your home screen, search for OnStream, select it, and choose Install. The app then downloads and appears on your home screen ready to open. You do not need a computer or any technical setup beyond what your Firestick already has.

The process is the same whether you own a Firestick 4K, Firestick HD, or an older generation device. If you have already installed other apps from the Appstore, you already know the steps.

Key Takeaways

  • OnStream installs directly from the Amazon Appstore using your Firestick remote and takes about two minutes from start to finish.
  • You need an active internet connection on your Firestick, but you do not need to pair it with a phone or computer.
  • After installation, the app appears as a tile on your Firestick home screen and opens like any other app you have installed.
  • If the install button does not appear, your Firestick may not have enough storage space — deleting unused apps can free up room.

Step-by-step installation from the Appstore

Start at your Firestick home screen. Using your remote, navigate to the top menu and select the magnifying glass icon to open search. Type "OnStream" using the on-screen keyboard. The app name appears in the results below.

Select OnStream from the search results. A detail page opens showing the app name, a description, and an Install button. Press the Install button on your remote. A progress bar appears while the app downloads — this usually takes 30 seconds to two minutes depending on your internet speed.

Once the read finishes, the Install button changes to Open. You can select Open to start the app right away, or press the back button to return to your home screen. OnStream now appears as a tile on your home screen alongside your other apps.

What to do if OnStream does not appear in search results

If you search for OnStream and the app does not show up, the most common reason is that your Firestick is set to a different region or country than where OnStream is available. Check your Firestick settings by going to Settings > Device > About and looking at the country listed there. OnStream may not be distributed in all regions through the Amazon Appstore.

A second reason is that your Firestick software is out of date. Go to Settings > Device > About > Check for System Update. If an update is available, install it and restart your device, then search for OnStream again.

If OnStream still does not appear after checking your region and updating, the app may not be available for your specific Firestick model. Older first-generation Firesticks sometimes have limited app availability. Check the Amazon Appstore page for OnStream on a computer or phone to see which devices it supports.

Freeing up storage space if the install fails

If you tap Install and nothing happens, or you see an error message, your Firestick may not have enough free storage. Firesticks have limited built-in storage, and apps, cached data, and system updates take up space over time.

To free up space, go to Settings > Apps > Manage Installed Apps. Look at the list of apps you have installed. Select any app you no longer use, then choose Uninstall. Repeat this for two or three unused apps. After uninstalling, return to the Appstore and try installing OnStream again.

You can also clear the cache for apps you want to keep. Go to Settings > Apps > Manage Installed Apps, select an app, and choose Clear Cache. This removes temporary files without deleting the app itself. Clearing cache for three or four apps often frees up enough space for a new installation.

Signing in to OnStream after installation

Once OnStream opens for the first time, you will see a login screen. If you have an existing OnStream account, enter your username and password. If you do not have an account, look for a Sign Up or Create Account button on the login screen and follow the prompts.

Some versions of OnStream may ask for permission to access your Firestick's network connection or to send notifications. These are standard requests and allow the app to stream video and send you updates about new content. You can usually change these permissions later in your Firestick settings if you change your mind.

Troubleshooting if OnStream crashes or will not open

If OnStream installs but crashes when you try to open it, the first step is to force-close the app. Go to Settings > Apps > Manage Installed Apps, select OnStream, and choose Force Stop. Wait 10 seconds, then select OnStream again and choose Open.

If the app still crashes, uninstall it completely by selecting Uninstall from the same menu. Restart your Firestick by going to Settings > Device > Restart. After the restart, go back to the Appstore and install OnStream again. A fresh installation often fixes crashes caused by corrupted files or conflicting settings.

If OnStream continues to crash after a fresh install, check that your Firestick has the latest system software. Go to Settings > Device > About > Check for System Update. Install any available updates and restart, then try opening OnStream again.

Removing OnStream if you no longer want it

To uninstall OnStream, go to Settings > Apps > Manage Installed Apps. Find OnStream in the list, select it, and choose Uninstall. The app is removed from your Firestick and the storage space it used is freed up. You can reinstall it at any time by returning to the Appstore and searching for it again.

If you want to keep the app but remove it from your home screen, you can hide it instead. From your home screen, highlight the OnStream tile, press the menu button on your remote (three horizontal lines), and select Remove from Home. The app stays installed but no longer appears on your main screen.

Frequently Asked Questions

Do I need an Amazon Prime membership to install OnStream?

No. The Amazon Appstore is available to all Firestick owners regardless of Prime membership. You can search for and install OnStream without a Prime account. However, OnStream itself may have its own subscription or account requirements once you open the app.

Can I install OnStream on multiple Firesticks in my home?

Yes. Each Firestick can install apps independently from the Appstore. Search for OnStream on each device and install it separately. If you use the same Amazon account on multiple Firesticks, some apps allow you to sign in once and access your account across all devices, but this depends on how OnStream handles multi-device logins.

What internet speed do I need to install OnStream?

A standard home internet connection is sufficient. The app read itself is small and usually completes in under two minutes on any connection faster than 5 Mbps. Streaming video through OnStream after installation may require faster speeds depending on the video quality you choose.

Will installing OnStream slow down my Firestick?

OnStream uses a small amount of storage and memory once installed, but it does not run in the background unless you open it. Your Firestick's overall speed should not be noticeably affected. If your device feels slow after installing multiple apps, clearing cache or uninstalling unused apps can help restore performance.

Can I install OnStream on a Firestick Cube or Fire TV device?

The installation process is identical on Firestick Cube and most Fire TV devices. Search the Appstore, find OnStream, and install it the same way. Availability may vary by region and device model, so if OnStream does not appear in search, check the Amazon Appstore page on a computer to confirm it supports your specific device.
