Introduction
Installing the UHF app on Apple TV and iPhone is straightforward once you know which type of IPTV login you received. The important part is choosing the correct playlist option: Xtream when you have a server address, username and password, or M3U/M3U8 when you have one long playlist URL.
This guide walks you through both Apple devices, explains the easier iPhone-first setup, shows you how to avoid the most common login mistakes, and helps you decide whether a problem belongs to your IPTV provider or the UHF app.
The correct App Store listing is called UHF - Love your IPTV, published by Short Wavelength Applications Ltd. It currently supports iPhone and Apple TV as well as M3U8 and Xtream playlists. The present Canadian App Store requirements are iOS 16 or later for iPhone and tvOS 17 or later for Apple TV.
Important: UHF is a media player, not an IPTV subscription. It does not supply channels, movies or television series. You need your own authorized playlist or login details from a provider like Nordix.

What You Need Before Installing UHF
Security note: Do not publish your M3U URL or show it in an unblurred screenshot. Many playlist URLs contain the username and password inside the link.
Xtream Codes vs M3U — Which One to Choose?
Use the information supplied by Nordix to identify the correct option:
| What you received | Option in UHF | Information to enter |
|---|---|---|
| Server/portal URL, username, password | **Xtream** or Xtream Playlist | Playlist name, server URL, username, password |
| One long web address with playlist info | **M3U** or M3U8 | Playlist name, complete M3U URL |
| Playlist URL + separate EPG URL | **M3U/M3U8** | Playlist URL and EPG URL |
Xtream is usually easier for beginners. Xtream separates the information into individual fields, making mistakes easier to identify. A typical set of details looks like this:
Enter only the server or portal address in the server field. Do not paste an entire M3U link into that field.
M3U is useful when your provider sends one complete link. Because M3U links can be long, adding the playlist on iPhone is normally more convenient than entering it directly with an Apple TV remote.
How to Install UHF on iPhone
Step 1: Check your iPhone software version
Go to Settings > General > Software Update. Install any available iOS update. UHF requires iOS 16 or later.
Step 2: Find the correct UHF app
Step 3: Start a new UHF setup
Open UHF. On the first screen, choose the option to begin a new setup. Depending on the version, this may be labelled: Start From Scratch, Add Playlist, Create Playlist, or Add Source. Do not select Stremio or Jellyfin when your provider supplied normal Xtream or M3U IPTV credentials.
Step 4: Add Nordix using Xtream details
Choose Xtream, Xtream Codes or Xtream Playlist, then complete the displayed fields:
Tap Save. UHF should retrieve the playlist.
Step 5: Add Nordix using an M3U URL
Choose M3U or M3U8 instead of Xtream:
Do not shorten, edit or remove parameters from the M3U URL unless support instructs you to do so.
Step 6: Test the playlist properly
Do not consider the setup complete after opening only one channel. Test:
How to Install UHF on Apple TV
Step 1: Check the Apple TV software
Go to Settings > System > Software Updates. Install any available update. UHF requires tvOS 17 or later.
Step 2: Install the correct UHF app
You do not need to jailbreak or sideload the application — UHF is distributed through Apple's App Store.
Step 3: Choose your Apple TV setup method
Method A — Enter the playlist directly on Apple TV
Xtream is usually more convenient for direct Apple TV entry because its fields are shorter than a full M3U URL.
Method B — Set up iPhone first and use device sync (recommended)
This is the more comfortable workflow when you have a long M3U URL or complex password:
Make Apple TV typing easier with your iPhone. When a text field appears on Apple TV, a nearby iPhone or iPad can display a keyboard notification. Tap it and type on the iPhone keyboard instead of navigating with the TV remote. This is especially useful for long server URLs, passwords with symbols, and M3U links.
Can You Use UHF on iPhone and Apple TV at the Same Time?
Installing UHF on two devices does not automatically give you two simultaneous streams. UHF controls where the app can be installed, while your IPTV plan controls how many streams can play at once.
Nordix plans include access on all your devices with one stream at a time. Before testing Apple TV, stop playback on the iPhone. If Apple TV begins working after closing the iPhone stream, you may have reached the connection limit.
Recommended UHF Settings for Reliable Playback
1. Match the stream format to your connection
Experiment with TS and M3U8 output formats. When a high-quality connection is available, TS often provides better seeking and audio synchronization. On cellular or unstable Wi-Fi, M3U8 adapts to bandwidth fluctuations.
2. Do not force a zero-second buffer
UHF allows the buffer to be set to zero for faster loading, but this depends on a strong connection. When playback becomes unstable, return the buffer to at least one second under Settings > Video Player.
3. Set English or French audio preferences
UHF supports multiple audio tracks and subtitle options. Canadian and Quebec viewers should check their preferred language settings rather than assuming a missing track is an app failure.
4. Create favourites after the playlist is stable
Before arranging categories: confirm the playlist updates correctly, test live channels and on-demand content, verify EPG data loads, then add favourites and hide unused categories.
5. Treat a VPN as optional
UHF offers built-in support for several VPN providers. A VPN may help with privacy or diagnosing network-routing problems, but it will not repair an expired subscription, an incorrect password, or a missing channel.
UHF App Not Working? Troubleshooting Guide
| Problem | Likely cause | What to do |
|---|---|---|
| UHF does not appear in App Store | Unsupported software version or regional issue | Update iOS/tvOS, search exact app name, verify developer |
| "Invalid login" or playlist rejected | Incorrect URL, port, username, password or playlist type | Check each field character by character, confirm Xtream vs M3U |
| Every channel buffers | Wi-Fi congestion, routing, background downloads | Test Ethernet or 5 GHz Wi-Fi, pause downloads, restart router |
| No sound or wrong language | Alternate audio track selected | Open playback controls, select another audio track |
| Subtitles missing | Subtitle track not provided by source | Check available tracks, try another title |
| App closes or freezes | App or OS problem | Update UHF and tvOS/iOS, restart device, reinstall as last resort |

Frequently Asked Questions
Is the UHF app free?
UHF includes core playback functionality in a free tier. Optional UHF Pro features include cross-device synchronization, removal of advertisements, expanded EPG navigation, reminders and Family Sharing.
Does UHF include IPTV channels?
No. UHF is a media player and does not provide, host or distribute channels. You must add your own authorized Xtream, M3U8 or other supported source from Nordix.
What iPhone version is required?
iOS 16 or later.
What Apple TV version is required?
tvOS 17 or later. Check Settings > System > Software Updates before installation.
Is Xtream or M3U better for UHF?
Choose the format Nordix supplied. Xtream is often easier to enter and troubleshoot. M3U is appropriate when you receive one complete playlist URL.
Do I need UHF Pro?
No. The free tier includes core playback. UHF Pro adds optional features like cross-device sync and extended EPG navigation.
Can I use the same playlist on iPhone and Apple TV?
Yes, but simultaneous playback depends on your plan's connection allowance. Stop playback on one device when testing the other.
Why does UHF work on iPhone but not Apple TV?
Common causes include an older tvOS version, a connection limit, a typing error in credentials, or a different network route. Update Apple TV, stop the iPhone stream, and enter the playlist manually as a comparison test.
Why is the UHF EPG blank?
Refresh the playlist and allow the guide time to import. If the problem persists after a full refresh, contact Nordix support to verify EPG availability for your subscription.
