Polygon reported last week that Xbox’s answer to the PlayStation Platinum has finally leaked. Internal builds refer to it as the “Mythic Achievement” tier, a per-game top badge that unlocks when every regular achievement is earned. That is a real change to the shape of the Xbox completion hobby. For years the community lived on total gamerscore. A per-game apex changes what people chase, and it changes which tracking tools are worth having on the phone.
We rebuilt our achievement-tracking stack against the new mechanic. Seven Android apps that show progress, surface the shortest completions, and warn you before you tick past the point where a Mythic becomes unreachable. Ranked by how quickly each one lets you decide “next” without leaving the couch.
What matters when tracking Xbox completion on a phone
- Live sync with Xbox Live. Achievements should reflect the last unlock within a minute, not the last time the app was open.
- Mythic tier surfacing. Any app worth keeping through the transition should have a filter for “games I can still Mythic” versus “already missed the window.”
- Time-to-complete estimates. Chasing badges is more fun when you know the game is a weekend rather than a month.
- Missable-achievement warnings. The kind of tool that pings before you enter chapter 8 in a game where an early-chapter achievement is locked out afterward.
- Community leaderboards. Completion is a social hobby. Comparing progress with friends and a global list keeps it moving.
- Game Pass integration. Roughly a third of the achievement chases people set for themselves are on Game Pass titles. The tool should surface which of those are leaving the service.

The apps
1. Xbox — Best official completion view
Xbox is the first-party app and it is the one that will support Mythic first when the tier ships publicly. Live sync with your gamertag is instant. Achievement lists are complete. Cross-check against friends is one tap. If Mythic lands in the app UI the day it launches (and it likely will), no third-party tool will be ahead of it.
Where it falls short: Community weighting is thin compared to TrueAchievements. Sort and filter options are basic. Big libraries are slow to scroll.
Pricing:
- Free: everything, forever
- Paid: none
Platforms: Android, iOS, web
Download: Xbox on Aptoide · Google Play
Bottom line: The default. Keep it installed regardless of which third-party tracker you pair it with.
2. TrueAchievements — Best community depth
TrueAchievements has been the completion-hunter’s home for over a decade. The site’s TA-score weights achievements by how many players earn them, so a rare drop is worth more than a story-mode gimme. The Android app pulls the same data into a phone-friendly view and adds walkthroughs, missable warnings, and community-verified game guides.
Where it falls short: The free tier shows ads and caps some social features. Some walkthroughs are years old and predate DLC changes.
Pricing:
- Free: full tracking with ads
- Paid: TA Pro at about 4 USD/month for ad removal and premium features
Platforms: Android, iOS, web
Download: TrueAchievements on Aptoide · Google Play
Bottom line: Pair it with the Xbox app for anything more serious than “did I unlock that yet?”
3. Exophase — Best cross-platform trophy view
Exophase solves a specific problem: seeing Xbox, PSN, and Steam completion in one profile. If you play across two platforms and want to plan a completion run without switching apps, Exophase is the pick. The Android app is a browser-first experience wrapped in a mobile shell, which sounds bad but works because the site was already mobile-friendly.
Where it falls short: The mobile UI is not native-feeling. Some sections require web fallback. Ad density is heavier than TrueAchievements.
Pricing:
- Free: full profile with ads
- Paid: donation-based Premium removes ads
Platforms: Android, iOS, web
Download: Exophase on Aptoide · Google Play
Bottom line: Pick this if you play on both Xbox and PlayStation and want a single view.
4. Achievement Watcher — Best for real-time alerts
Achievement Watcher is a niche pick that earns its slot by pushing you a notification when a friend unlocks a rare achievement or when you unlock one yourself. Not just “you completed a game,” but “you got a Mythic that only 0.4% of players have.” That is a hobbyist’s tool, but the hobby is exactly what a Mythic tier reinforces.
Where it falls short: Setup requires linking Xbox Live via OAuth and the reauth cycle is fussy. UI is dated.
Pricing:
- Free: full functionality
- Paid: none
Platforms: Android
Download: Achievement Watcher on Aptoide · Google Play
Bottom line: Pick this if the social element of completion is what keeps you playing.
5. Xbox Game Pass Companion — Best Game Pass rotation view
Xbox Game Pass Companion is a fan-made app that tracks the Game Pass catalogue: what is joining, what is leaving, what has hidden Mythic-worthy achievement lists. The “leaving in 14 days” list is the single most useful feature for anyone completing games on the service, because a game that leaves the catalogue is likely also leaving your practical Mythic window.
Where it falls short: Unofficial, so the roadmap depends on hobbyist maintenance. The developer usually catches Microsoft’s list changes within a day, but not immediately.
Pricing:
- Free: everything
- Paid: none
Platforms: Android
Download: Xbox Game Pass Companion on Aptoide · Google Play
Bottom line: Pick this if a meaningful part of your library rotates in and out of Game Pass.
6. HowLongToBeat — Best completion-time estimates
HowLongToBeat answers “how long is this game” with community-sourced hour counts split by “Main Story”, “Main + Extras”, and “Completionist”. The last one is exactly the Mythic path. On the Android app, adding a game to your completion queue and sorting by the completionist estimate makes the “what should I play next” question a two-tap decision.
Where it falls short: Community estimates lag when a game gets new DLC. No integration with Xbox Live sync out of the box, so you cross-reference manually.
Pricing:
- Free: full site access with ads
- Paid: Supporter at about 3 USD/month for ad removal and premium sorts
Platforms: Android, iOS, web
Download: HowLongToBeat on Aptoide · Google Play
Bottom line: Add this to the stack once, use it every time you pick the next completion target.
7. MyAchievements — Best personal completion diary
MyAchievements is a lightweight diary rather than a full tracker. You mark games as “in progress”, “completed”, “Mythic goal”, or “abandoned”, and the app graphs the progress week over week. The point is not community stats. It is the private record of “I finished X in September” that some players find motivating.
Where it falls short: No Xbox Live sync, so entry is manual. The free tier limits the diary to 20 active games.
Pricing:
- Free: 20 games in the active diary
- Paid: Pro at about 4 USD/month for unlimited diary size
Platforms: Android
Download: MyAchievements on Aptoide · Google Play
Bottom line: Pick this if you want a personal record and do not care about community stats.
How to choose
- If the goal is the official view with future Mythic support: Xbox app.
- If you want community depth: TrueAchievements.
- If you play on Xbox and PlayStation both: Exophase.
- If a friend’s rare unlock is your dopamine hit: Achievement Watcher.
- If Game Pass rotation drives your queue: Xbox Game Pass Companion.
- If “how long is this” is the deciding question: HowLongToBeat.
- If a private log matters more than a public one: MyAchievements.
Stay off the trackers entirely if you play for the game and not for the badge. Mythic is a tier, not a mandate. The tools above are for the specific hobby of chasing completion, which is not everyone’s flavour.
FAQ
When does the Xbox Mythic Achievement tier officially launch? Xbox has not confirmed a date. The leaked internal builds suggest a rollout inside a future dashboard update, likely tied to the next major Xbox app refresh. Expect first-party support in the Xbox app before third-party trackers.
Will the Mythic tier apply to old games retroactively? Almost certainly yes. Sony’s Platinum applies to any full-completion PS3 title released after the mechanic launched. Xbox will likely take a similar retroactive approach for titles with a complete achievement list.
Does TrueAchievements support Mythic already? Not officially at time of writing. The community expects a same-week update once Microsoft publishes the tier flag in the Xbox Live API.
Which app tells me the shortest completion path? HowLongToBeat for the time estimate, TrueAchievements for the difficulty-weighted list of which achievements you have left.
Can I track Steam achievements alongside Xbox in the same app? Exophase is the pick for that. TrueAchievements is Xbox-primary with limited Steam support.
