Last updated: July 2026 Vizio smart TVs work differently from Roku or Fire TV: there’s no app store to download from — every supported app comes pre-installed, and new ones appear automatically through updates. Press Home (or the V button), scroll the app row, and launch. Hulu is already there on every SmartCast/VIZIO OS set; Spectrum TV has recently been added to Vizio’s catalog on newer VIZIO OS models; Xfinity Stream still isn’t available on any Vizio and needs the casting workaround below. Here’s exactly how to find, add and arrange apps on your Vizio — and what to do when the app you want isn’t supported. 
Step 1: Know Which Vizio You Have
Three eras, three answers: VIZIO OS (newest models, after Walmart’s 2024 acquisition): press Home, open the side menu → Apps, and use App Search to look for a specific app and Home Screen Apps to choose what shows on your row. Same platform as SmartCast underneath — instructions are interchangeable. SmartCast (2016–2024): no search, no store — the app row is the catalog. All 250+ supported apps load automatically once the TV is online; new apps appear by themselves after firmware updates. VIA / VIA+ (before 2016): these used the V button → Connected TV Store to install apps — but that store has been discontinued, so pressing V now leads to a frozen or empty catalog. Nothing new can be added natively; skip to the streaming-stick section for these sets.
Step 2: Add or Find an App (SmartCast / VIZIO OS)
1. Connect the TV to the internet: Menu → Network → Wireless, pick your Wi-Fi, enter the password. 2. Press Home/V — the full app row loads across the bottom. 3. On VIZIO OS, use App Search; on SmartCast, scroll the row — if Vizio supports the app, it’s already there. 4. Missing? Run a firmware update (Menu → System/Admin → Check for Updates) — Vizio pushes new apps server-side, and an out-of-date TV shows an out-of-date app row. 5. Tidy the row: highlight an app, hold OK, and drag it to a new position so your daily apps sit first. Pre-installed apps can be rearranged but not uninstalled.
Hulu on a Vizio TV
Pre-installed on every SmartCast and VIZIO OS set — press Home, find Hulu on the row, sign in and stream. If it misbehaves (black screen, endless load), power-cycle the TV at the wall for 30 seconds; that clears the platform cache and fixes most app crashes. Choosing a plan first? Our Hulu plans and prices guide compares them.
Spectrum TV on a Vizio TV
The situation changed recently: Spectrum TV is now listed in Vizio’s official app catalog, appearing on newer VIZIO OS models. So check your TV first — App Search (or the app row after a firmware update). If it’s there: launch, sign in with your Spectrum credentials (an active Spectrum TV plan is required — internet-only accounts can’t log in), and you’re done.
If your model doesn’t have it — true for most pre-2024 SmartCast sets — cast instead: 1. Put your phone and TV on the same Wi-Fi network. 2. Open the Spectrum TV app on your phone, play a channel. 3. Tap the Cast icon and pick your Vizio (every SmartCast set from 2018 on has Chromecast built in; iPhones can use AirPlay 2 on 2018+ models). 4. The stream moves to the TV; your phone becomes the remote and can even lock while playback continues.
Xfinity Stream on a Vizio TV
Not available natively on any Vizio, old or new. Two working routes: cast the Xfinity Stream app from your phone exactly as in the Spectrum steps above, or sign in at xfinity.com/stream in Chrome on a laptop and cast the browser tab to the TV (Chrome menu → Cast). For a permanent big-screen setup, the streaming stick below is the cleaner answer — the Xfinity Stream app runs natively on Roku and Fire TV.
The App Isn’t Supported at All? The $30 Fix
When Vizio’s catalog simply doesn’t carry what you need — or your TV is a pre-2016 VIA model — a streaming stick in the HDMI port ends the problem permanently: a Roku Express or Fire TV Stick costs around $30, carries thousands of apps including Spectrum and Xfinity Stream, and outperforms the built-in platform on older sets anyway. Setup takes ten minutes; our Roku setup guide walks through it.
Casting Won’t Connect? Three Fixes in Order
1. Same network, same band: the phone on “HomeWiFi-5G” and the TV on “HomeWiFi” counts as different networks to Chromecast — match them exactly. 2. Power-cycle the TV (unplugged 30 seconds) — clears the cast cache that silently breaks after router changes. 3. Update both ends: the TV’s firmware and the phone app. Vizio’s casting bugs are patched throughout the year, and stale firmware is the most overlooked cause of “TV not found.” One question we get often enough to answer here: can you download apps like on a phone? No — and that’s not a fault with your TV. Vizio chose a curated, auto-updating catalog instead of an open store. Everything supported arrives on its own; everything else casts or runs from a stick. And a warning about advice you’ll meet elsewhere.
Vizio TVs cannot sideload apps from a USB drive or APK files — SmartCast isn’t Android, the USB port is for media playback only, and guides claiming otherwise are describing a different brand of TV. Don’t chase that route; it doesn’t exist on Vizio. Which app were you trying to add? If it’s not covered above, name it in the comments and we’ll find the route.
