Which TCL Roku Remote App Is Best for iPhone?

I run a TCL 4-Series Roku TV (43S435) and drive it from an iPhone 15. When the stock remote's battery door snapped off, I went a month on the phone alone and barely noticed. My honest take: the official Roku app is the most complete, but the mandatory account is a speed bump — so for a quick, no-login remote I reach for a universal app, and I keep AirPlay for tossing a video up without opening any remote at all.

Below are the three free ways to control a TCL Roku from an iPhone, ordered official-first, each with exact steps and the honest catch. Want the full first-time pairing walked through in detail? See the TCL Roku TV remote app setup guide. On Android rather than iPhone? The cross-platform TCL Roku remote app guide covers both phones. Weighing every app, not just iPhone? The TCL TV remote app overview compares them all. Not sure your set even runs Roku? Our TCL remote finder tool checks it in a few taps, and the Roku remote identifier pins down which Roku remote you own and its size.

The 30-second test

Before you download anything, figure out which option fits. It comes down to whether you want an account and how much control you need. This quick check points you at the right method below.

1. 1Want the platform's exact button layout and private listening? The official Roku app (Method 1) is the fullest, but it needs a free Roku account.
2. 2Want a remote with zero sign-in, or you also own a non-Roku TV? A universal app (Method 2) skips the account and covers both platforms.
3. 3Just want to throw a video or photos on the screen? AirPlay (Method 3) is built into your iPhone — no remote app at all.

Method 1: The official Roku app

A TCL running Roku is a Roku device, so Roku's own app is the official remote — there's no separate TCL download. It's the most complete option: the exact button layout, keyboard search, voice, and private listening through headphones on your iPhone. Roku publishes it on roku.com.

1. 1Install the free Roku app on your iPhone. Open the App Store on your iPhone, download the official Roku app, and sign in with a free Roku account. It's the same app Roku publishes for every Roku device, so it treats your TCL Roku TV like any other.
2. 2Join the same Wi-Fi as your TCL Roku TV. Put your iPhone on the exact Wi-Fi network the TV uses. iPhones have no infrared, so the app reaches the TV over that shared network — a mismatched band or guest network is the usual reason pairing fails.
3. 3Open the Devices tab and tap your TCL. In the Roku app, tap Devices at the bottom and wait for the scan. Your TCL Roku TV shows up by name; tap it, and enter the on-screen code if the app asks for one.
4. 4Control the TV from your iPhone. Use the D-pad, OK, back, volume, and keyboard search just like the plastic remote. Private listening pipes the TV's audio to headphones on your iPhone when you tap the headphones icon.

Catch: the Roku account sign-in is required before the app will pair, and the app only drives Roku sets — a TCL Google TV in the house needs Google's app instead. If the scan just spins, the setup guide's troubleshooting steps clear most stuck pairings.

Method 2: A no-account universal app

If the mandatory Roku account puts you off — or you also own a non-Roku TV — a universal app skips the sign-in entirely. Smart TV Remote finds your TCL Roku on the network and connects with no account, and the same app also pairs with TCL Google TV sets, so one download covers a mixed household.

1. 1Download Smart TV Remote free from the App Store on your iPhone or iPad.
2. 2Put your iPhone on the same Wi-Fi as the TCL Roku TV — no infrared means it works over the network.
3. 3Open the app, let it scan, and tap your TCL Roku in the detected list. No code or account needed.
4. 4Use the D-pad, OK, volume, playback, and the iPhone keyboard for fast search.

Catch: private listening through headphones is a Roku-app feature, so a universal app may not offer it. For that one perk, keep the official app installed alongside. Own a Google TV TCL too? The TCL Google TV remote app guide covers that side.

Method 3: AirPlay from Control Center

Every current TCL Roku TV supports AirPlay 2, so your iPhone can stream or mirror to it with no remote app at all. It's the fastest way to put a video, photos, or your whole screen on the TV — you control playback from the iPhone itself. Roku documents AirPlay support on its official AirPlay help page.

1. 1Put your iPhone and the TCL Roku TV on the same Wi-Fi network.
2. 2In a video app, tap the AirPlay icon; or open Control Center and tap Screen Mirroring to send your whole screen.
3. 3Pick your TCL Roku TV from the list, and enter the code shown on the TV the first time.
4. 4Play, pause, and scrub from your iPhone — the TV mirrors what you do.

Catch: AirPlay controls playback and mirroring, not the Roku home screen — you can't open apps or navigate menus with it. Treat it as a companion to a remote app, not a full replacement. If nothing connects at all, work through the TCL remote not working checklist.

Fix 1: When your iPhone can't find the TV

If a remote app keeps scanning and never lists your TCL Roku, the cause on an iPhone is usually one of two iOS-specific things, on top of the usual Wi-Fi mismatch. Work through these in order.

1. 1Allow Local Network access: open iOS Settings › the remote app, and switch Local Network on. iOS blocks device discovery until you grant this, and the first-launch prompt is easy to dismiss by accident.
2. 2Turn off iCloud Private Relay and any VPN: Settings › your name › iCloud › Private Relay off, then reopen the app — both can hide the TV from the scan.
3. 3Match the exact Wi-Fi: confirm the iPhone is on the same network name and band as the TV, not a guest or 5 GHz-only network the TV can't see.
4. 4On the TV, open Settings › System › Advanced system settings › Control by mobile apps and set it to Enabled (Default or Permissive).

Honest note: some older routers block the discovery both apps rely on (AP isolation or IGMP snooping). If nothing above works, that router setting is the likely culprit — AirPlay in Method 3 often still works because it uses a slightly different path.

Which iPhone option fits you?

All three control a TCL Roku TV from your iPhone. They differ on whether you need an account, how much you can do, and whether they reach a non-Roku set as well.

My pick for most iPhone owners: start with the no-account universal app for everyday control, add the official Roku app if you want private listening, and lean on AirPlay for quick streaming. If your stock remote is gone for good, the lost-remote guide covers finding or replacing it.
