To help us answer quickly, please include: your iPhone model and iOS version, your Roku model and Roku OS version (on the TV: Settings › System › About), whether the phone and the TV are on the same Wi-Fi network, and a short description of what happened.
Both devices must be on the same Wi-Fi network: not the guest network, and not cellular data. Wake the Roku with its own remote first. Then check the setting that lets apps control the TV: on the Roku, open Settings › System › Advanced system settings › Control by mobile apps › Network access and choose Enabled (called Default on older software). On Roku OS 14.1 and later this is set to Limited out of the box, which blocks every remote app. Back in Hero Remote, tap Search again, or add the TV by its IP address under More › Manual IP Setup. The TV shows its IP address under Settings › Network › About.
Hero Remote needs this permission to talk to your Roku over Wi-Fi; without it no device can be found. Allow it when asked. If you declined, turn it on later in iPhone Settings › Privacy & Security › Local Network › Hero Remote.
The Roku’s Network access setting described above is set to Limited, so it refuses commands. The app shows the exact steps. Change the setting on the TV, then reconnect.
Turn on Wi-Fi on the iPhone, join the network your Roku uses, and tap Try again.
Streaming sticks and some players have no power or volume control over the network. That is a limitation of the device, not of the app. Roku TVs support all keys, including power, volume and mute.
Photos, videos and music from your phone, up to 50 items at a time, and videos found on web pages in the app’s built-in browser. Casting uses CastHero App, our own free channel for Roku. The first time you cast, the app offers to add it to your TV; adding it takes two OK presses on the TV.
Open More › Cast Photos and Videos and follow Add CastHero App to your TV. If the TV is signed out of its Roku account, channels cannot be added; sign in on the TV first, then try again.
Videos from streaming services that use copy protection (Netflix, YouTube, Disney+, Prime Video and similar) cannot be cast by any third-party app. The app tells you when a page is protected.
The Roku shows photos at the TV’s aspect ratio, so portrait photos get side bars. HEIC photos are converted on the phone before they are sent, which can take a moment for large images.
Remote Pro unlocks the volume keys and casting. Plans: weekly, monthly and annual auto-renewing subscriptions, and a Lifetime one-time purchase. Prices are shown in the app in your local currency.
The Watch app is a mini remote with direction, playback and volume pages. It relays every key through your iPhone, so the phone app must be installed and the phone must be on the same Wi-Fi as the Roku. It appears on the Watch automatically after the iPhone app is installed; if it does not, open the Watch app on the iPhone and install Hero Remote from the list.
The widget sends Back, Home, Play/Pause, Power and the volume keys to your last TV straight from the Home Screen (volume needs Remote Pro). Add it from the Home Screen’s edit mode: choose Hero Remote and pick the small or the medium size.
No account, no sign-up. The app talks to your Roku on your local network. We use Firebase Analytics and Crashlytics for anonymous usage counts and crash reports: no advertising identifier, no tracking across apps, no ads. Full details are in the Privacy Policy.
