How to Download an App on an LG Smart TV

LG Smart TVs make it relatively straightforward to expand what your television can do — but the exact process depends on which operating system your TV runs, how old it is, and what apps are actually available in your region. Here's a clear walkthrough of how app downloading works on LG TVs, along with the variables that affect what you can and can't install.

Understanding LG's Smart TV Operating System

Most LG Smart TVs manufactured from 2014 onward run webOS, LG's proprietary smart TV platform. Older models ran earlier software called Netcast, which has a more limited app ecosystem and doesn't support the same download process described here.

If your TV is running webOS, it has access to the LG Content Store (rebranded as LG ThinQ App Store on newer models) — LG's built-in marketplace for streaming apps, games, and utilities. This is the primary and recommended channel for downloading apps.

How to Download an App on an LG Smart TV 📺

The standard process on a webOS LG TV goes like this:

1. Press the Home button on your LG Magic Remote or standard remote. This opens the launcher bar at the bottom of the screen.
2. Navigate to the LG Content Store (or Apps, depending on your webOS version). It typically appears as a tile in the home row.
3. Search or browse for the app you want. You can search by name using the on-screen keyboard or browse by category.
4. Select the app and open its detail page.
5. Click "Install" — most apps are free to download, though some may require a subscription or in-app purchase to use.
6. Once installed, the app appears in your home screen launcher bar and can be pinned for quick access.

That's the core flow. On webOS 6.0 and later (found on 2021+ LG TVs), the interface looks slightly different — the home screen is more grid-based — but the underlying steps remain the same.

What Affects Which Apps You Can Install

Not every app is available on every LG TV, and a few key factors determine what shows up in your Content Store:

webOS version is the biggest variable. LG has released multiple webOS versions over the years (1.0 through 7.x and beyond), and app developers build for specific versions. A streaming app that runs on webOS 6 may not have a compatible version for webOS 3. Older TVs running earlier webOS versions often see apps discontinued or unavailable simply because developers stop maintaining older builds.

Geographic region also filters the Content Store. Apps available in the US, UK, or Australia may not appear in other regions, and vice versa. This is controlled at the account and device level.

TV model and hardware can matter for more demanding apps or games. Some apps may require minimum hardware capabilities that older panels don't meet, even if the webOS version technically supports it.

LG account sign-in is required to download apps on most webOS versions. Without an account linked to the TV, the Install button may be grayed out or inaccessible.

What If the App You Want Isn't in the Store?

This is where things get more nuanced. Unlike Android-based smart TVs (such as those running Google TV or Android TV), LG's webOS is a closed ecosystem — you cannot sideload apps from outside the official store without developer mode access.

Developer Mode is a legitimate but unofficial workaround that LG provides for app testers. It allows loading apps via a desktop application called LG Developer Mode App, but it requires:

• A free LG developer account at the webOS developer portal
• A compatible PC to package and push the app
• Technical comfort with file formats like .ipk
• Re-enabling developer mode every 50 hours (a significant limitation)

This is meaningfully different from, say, sideloading an APK on an Android TV. It's more involved, and the apps installed this way won't auto-update or integrate with the LG ecosystem the same way store apps do.

Comparing App Availability by TV Type

LG's store covers most major streaming services — Netflix, Disney+, Prime Video, Apple TV, YouTube, Hulu, and more — but niche or regional apps are where gaps start appearing. 🔍

When the Store App Doesn't Work Properly

Occasionally, apps fail to install or launch even when they appear in the store. Common causes include:

• Insufficient storage — LG TVs have limited internal storage (often 4–16GB), and it fills up faster than most people expect
• Outdated firmware — the TV's system software may need updating before an app will install correctly
• Network issues — a weak or unstable Wi-Fi connection can interrupt downloads silently
• Regional mismatches — if your LG account region doesn't match your TV's region settings, installs can fail

Checking Settings → Support → Software Update before troubleshooting app issues is a reliable first step that solves more problems than it might seem like it should.

The Part That Depends on Your Setup

How smoothly this all works — and whether the specific apps you want are actually available — comes down to factors that vary from one TV to the next: the age of the device, the webOS version it shipped with, the region it's registered in, and what's currently supported by the developers of the apps you care about. A 2019 LG TV and a 2023 LG TV are both running webOS, but they live in meaningfully different ecosystems when it comes to app support.
