TiviMate isn't always easy to find through the Firestick's built-in app search, which is why the direct route is going straight to its own official site rather than relying on a search result or a random link someone posted elsewhere. That site is the authoritative source for the app, not a third-party mirror, which matters because sideloaded apps installed from the wrong place can be outdated or altered. You reach it by installing Downloader first, a free sideloading tool available directly in the Firestick's app store, then entering TiviMate's install link inside Downloader to fetch and install the real app.

Open TiviMate, choose the option to add a playlist, and enter either an Xtream Codes login, a username, password and server URL combination, or a direct M3U playlist URL, exactly as your provider gave it to you, including any port number. The app pulls the full channel list and EPG data automatically once the login succeeds, usually within a minute or two on a normal connection. If nothing loads afterward, double-check for a typo in the URL or login details first, since that's the single most common reason a fresh setup fails on the very first try.

TiviMate holds the entire visible channel list in memory the whole time it's running, and that memory use climbs steadily as the list grows larger. Once a list grows past roughly 18,000 visible channels, navigation and channel switching both start to visibly lag, independent of how fast your internet connection actually is. Hiding channel groups you don't watch is a real fix for this, not just a workaround, because it directly shrinks what the app has to keep loaded and manage in memory at any given time, rather than papering over the underlying cause with some other setting.

Setting the live buffer to none and switching to a public DNS resolver instead of your ISP's default are the two changes that most reliably improve live channel switching speed on a Firestick. A larger buffer smooths out momentary hiccups in playback but adds a small delay every single time you switch channels, since the app has to refill that buffer before playback starts again. For live TV specifically, most people prefer the faster switch over a slightly larger safety margin, since live viewing involves changing channels far more often than watching a single VOD title straight through.

TiviMate offers a free tier that covers core playback of your channel list without any real limitation on the channels themselves, plus a paid tier that adds extra customization and interface options on top of that same core functionality. Either tier works identically with the same Xtream Codes login or M3U playlist, so your channels play exactly the same either way regardless of which one you pick. The choice mostly comes down to how much you personally want to customize the look and layout of the app, not whether your specific channels will actually play.
