Xbox officially revealed the Mythic Achievement tier this week, its answer to the PlayStation Platinum. Every game gets a top badge unlocked when all regular achievements are earned. That flips the completion hobby on its head: total gamerscore mattered for the past two decades, and now the per-game cap does. If you follow Xbox completion from a PC or a Mac (Cloud Gaming counts), your tracking stack needs a refresh. Here are the best desktop apps for tracking Xbox Mythic achievements in 2026.
What matters for tracking Xbox completion on desktop
The old tools were built around gamerscore. Mythic shifts the math to per-game completion, so the tools you keep are the ones that rank games by completion delta, not by gamerscore reward. The best stack does five things: it pulls your live achievement list from Xbox Live, it sorts by “how close am I to a Mythic,” it warns you before a missable trophy passes, it estimates completion time from other players’ data, and it tracks Xbox Cloud Gaming plays alongside console and PC.
- Live progress across every Xbox platform (console, PC, Cloud)
- “Time to complete” estimates from real player data
- Missable achievement warnings before you cross the point of no return
- Sorting by nearness-to-Mythic, not by gamerscore
- Shareable completion lists so you can compare with a friend

|---|---|---|---|---|

The apps
1. TrueAchievements — best for Xbox-first ranking
TrueAchievements has been the completion community’s home for a decade. Its custom “TrueAchievement” ratio adjusts raw gamerscore by rarity, so a 50G achievement earned by one percent of players ranks higher than a 100G earned by everyone. With Mythic in play, its “estimated time to complete” now sorts games by how close you are to a Mythic badge.
Where it falls short: the free tier now shows more ads than it used to, and some solver-mode tools sit behind Pro.
Pricing:
- Free: full tracking, community walkthroughs
- Paid: TA Pro at a modest monthly fee for solver mode and no ads
Platforms: any browser on Windows, macOS, Linux; native iOS and Android
Download: TrueAchievements
Bottom line: the default tracker for anyone who cares about the Xbox completion order.
2. Exophase — best cross-platform view
Exophase covers Xbox, PlayStation, Steam, Retro, Nintendo, and mobile in one profile. If you play across systems, this is the tracker that shows a Mythic-adjacent view on Xbox next to a Platinum-adjacent view on PlayStation.
Where it falls short: the Xbox-specific UI is less deep than TrueAchievements; use both together.
Pricing:
- Free: full profile
- Paid: Exophase Premium at a modest monthly fee for advanced stats
Platforms: any browser
Download: Exophase
Bottom line: the cross-platform view that stops you from opening five tabs.
3. Achievement Watcher — best PC-native tracker
Achievement Watcher is an open-source Windows app that shows achievement pop-ups for Steam, Uplay, Xbox Live PC titles, and RetroArch, all in one overlay. When you unlock an achievement on the PC Xbox app, it triggers your own overlay instead of the (sometimes silent) Xbox toast.
Where it falls short: it does not track console achievements natively; pair with TrueAchievements for that.
Pricing:
- Free: GPL
Platforms: Windows
Download: Achievement Watcher
Bottom line: the pop-up overlay that makes PC Xbox achievements feel real again.
4. Xbox app — the official desktop client
Xbox app on Windows is the destination for PC Xbox Cloud Gaming and Game Pass. It also stores your achievement list, syncs with the account, and streams to your desktop. It is the source of truth for whether a Mythic actually landed on the account.
Where it falls short: the achievement UI inside the app is buried under the Game Pass storefront.
Pricing:
- Free: app
- Paid: Game Pass Ultimate at a modest monthly fee for Cloud Gaming
Platforms: Windows (native), macOS and Linux (Cloud Gaming via browser)
Download: Microsoft Store | Cloud
Bottom line: the official client and the account authority.
5. HowLongToBeat — best completion-time estimate
HowLongToBeat answers “how many hours until Mythic” using community submissions across main story, main plus extras, and completionist runs. That last number is what to watch when planning a Mythic run.
Where it falls short: community data is thin on new releases in the first weeks after launch.
Pricing:
- Free: full site
- Paid: HLTB Insights at a modest monthly fee for graphs and no ads
Platforms: any browser, iOS and Android apps
Download: HowLongToBeat
Bottom line: the reality check before starting a Mythic run.
6. Completionist.me — best personal dashboard
Completionist.me shows a personal completion dashboard across Steam and Xbox. Sorts by “distance to 100%” and tracks perfect runs against your library. Now that Mythic exists, it also flags your closest-to-Mythic titles.
Where it falls short: it does not yet cover PlayStation or Nintendo, so cross-platform completionists still need Exophase alongside.
Pricing:
- Free: full profile with weekly refresh
- Paid: Completionist Pro at a modest monthly fee for daily refresh
Platforms: any browser
Download: Completionist.me
Bottom line: the dashboard that reranks the library around what is now the important number.
7. Xbox Console Companion — best legacy sync
Xbox Console Companion is the older Windows app that predated the current Xbox app. It still syncs achievements on legacy Xbox 360 titles that occasionally lag the new app. Keep it installed if your Mythic hunt touches the 360 backward-compat catalog.
Where it falls short: Microsoft has been deprecating it in stages, so its future is not certain past 2027.
Pricing:
- Free
Platforms: Windows
Download: Microsoft Store
Bottom line: worth keeping for backward-compat titles until Microsoft fully sunsets it.
8. MyAchievements — best live toast overlay
MyAchievements is a lightweight Windows overlay that pops up achievement toasts, tracks a session, and pings a Discord webhook when a game rolls Mythic. Great for streamers who want a clean, custom-styled notification.
Where it falls short: setup for Xbox achievements needs the beta path via the Xbox app’s live feed.
Pricing:
- Free
Platforms: Windows
Download: MyAchievements on GitHub
Bottom line: the overlay to route Mythic events to Discord or an OBS scene.
How to pick the right one
If you want the default tracker, use TrueAchievements. If you play across platforms, pair it with Exophase. On Windows, add Achievement Watcher for pop-ups and MyAchievements if you stream. Use HowLongToBeat to plan the run, Completionist.me to prioritize the library, and Xbox Console Companion only if you touch Xbox 360 titles. The official Xbox app stays as the account authority.
FAQ
What is Xbox Mythic Achievement?
Mythic Achievement is a per-game top badge unlocked when every regular achievement in that game is earned. It is Xbox’s answer to the PlayStation Platinum trophy.
Do Mythic Achievements sync back to older games?
Yes, retroactively. Any game with a complete achievement list credits a Mythic once all listed achievements are earned, including older Xbox 360 titles with backward compatibility.
What is the best free Xbox achievement tracker?
TrueAchievements for depth, Exophase for cross-platform, Completionist.me for personal dashboards. All three are free at the tier most players need.
Can I track Xbox achievements on a Mac?
Yes, through any browser tracker (TrueAchievements, Exophase, Completionist.me). The Xbox app itself is Windows-native, but Cloud Gaming plays through the browser on macOS and Linux.
Do achievement pop-up overlays work with Xbox Cloud Gaming?
Partially. Overlays like Achievement Watcher hook into the Xbox app’s local process; Cloud Gaming runs in a browser tab, so most toasts still come from the Xbox web overlay rather than the desktop app.
