What happens if I get a new phone — will my progress carry over?

Yes. When you sign in on a new device, all your watch progress, watchlist, and preferences sync immediately from the cloud. Nothing is stored locally — your account data follows you.

Complete Guide: Setting Up Ultra 8K on Every Device

Ultra 8K is designed to work seamlessly on every screen you own. Whether you're setting up your first device or adding Ultra 8K to a new TV, phone, or computer, this guide walks you through every platform in one place.

Setting Up on Smart TV (Samsung, LG, Sony, and More)

Open your Smart TV's built-in app store. On Samsung, this is Samsung TV Plus or the Smart Hub. On LG, open the LG Content Store. On Sony (Android TV / Google TV), open the Google Play Store. Search for 'Ultra 8K', select Install, and wait for the download to complete (typically under a minute).

Once installed, open the Ultra 8K app and select Sign In. Enter your account email and password. If you're signing in for the first time on this TV, the app will download your watchlist and settings automatically. Select your preferred video quality in Settings > Video Quality — 'Automatic' is recommended unless you have a consistently fast connection, in which case 'Ultra HD' ensures maximum quality.

Setting Up on Fire TV

Navigate to the Find > Search function on your Fire TV home screen and search for 'Ultra 8K'. Alternatively, press and hold the microphone button on the Alexa remote and say 'Open Ultra 8K'. Select the Ultra 8K app from results and press Get or Download.

After installation, sign in with your account credentials. Fire TV Stick 4K and Fire TV Cube users should navigate to Settings > Display & Sound > Display > Video Resolution and set it to 'Auto (Up to 4K Ultra HD)' with HDR enabled. This ensures Ultra 8K can serve 4K HDR streams to your TV.

Setting Up on iPhone and iPad

Open the App Store on your iPhone or iPad and search for 'Ultra 8K'. Tap Get and authenticate with Face ID, Touch ID, or your Apple ID password. The app installs in seconds. Open it and sign in.

On iPhone, the app defaults to HD on cellular and Full HD on Wi-Fi. To change this, go to App Settings > Video Quality. For iPad, the app uses a two-panel layout in landscape mode — content browser on the left, details on the right. The player adapts to the full screen in landscape and maintains a comfortable aspect ratio in portrait.

Setting Up on Android Phones and Tablets

Open the Google Play Store, search for 'Ultra 8K', and tap Install. After installation, open the app and sign in. On Android tablets, the app automatically uses the large-screen optimised layout with the side-panel content browser.

Android users can also set Ultra 8K as a default streaming app in Google Assistant by saying 'Hey Google, set Ultra 8K as my default streaming service'. Chromecast is available from the player — tap the Cast icon to send the stream to any Chromecast on your network.

Setting Up on Windows and Mac

For Windows, the easiest way to start is to open Chrome, Edge, or Firefox and navigate to u8kott.cc. Sign in and stream directly in the browser. For the best experience, download the Windows app from the website — it supports hardware-accelerated 4K playback, a distraction-free full-screen mode, and a remote-friendly navigation layout.

On Mac, open Safari and navigate to u8kott.cc — Safari provides hardware-accelerated video decoding and HDR support on MacBook Pro. The macOS app from u8kott.cc adds a native menu bar integration and supports M-series Apple Silicon for maximum efficiency. Both platforms require macOS 12 or Windows 10 (version 2004) or later for the native apps.

Conclusion

Ultra 8K is designed so that setup on a new device takes under two minutes. Once signed in, everything syncs automatically — your watchlist, watch progress, and preferences are exactly as you left them on every other device. There's no per-device configuration beyond the initial sign-in.
