Overwatch 2 rank tracking that keeps the history
The career profile in the game shows you today. Mercy keeps the timeline, so you can see the trend instead of the snapshot.
- Pro
Rank history per role, not one number
Tank, Damage and Support each get their own chart, plotted from Bronze to Ultimate with win rate and KDA on the same timeline. Filter to 7, 30 or 90 days, or pick any range.

- Pro
See what every session cost you
Start a session before you queue, end it when you stop. Mercy snapshots your profile at both ends and shows the difference: games played, win-loss record, rank gained or lost. A session you would rather not count can be discarded.

Full career profiles for any BattleTag, free
Search a BattleTag and get competitive ranks, games, wins, win rate, KDA, most played heroes and best performances — PC and console, Competitive and Quick Play. Follow five players at no cost.

- Pro
Compare two players head to head
Drop two BattleTags in and read them in one column each: win rate, KDA, games, wins, hours and the rank in all three roles. Settles the argument in about ten seconds.

- Pro
Meta tier lists built from real win rates
Heroes ranked A to C by measured win rate, not by opinion. Filter by role and by rank bracket, because Bronze Tank and Grandmaster Tank are not the same game. Refreshed daily.

Free vs Mercy Pro
The free app answers "what are my stats". Pro answers "where is my rank going".

Mercy Pro is a subscription, billed through the store you installed from and cancelled there whenever you want.
No account. No user database.
There is nothing to sign up for. Mercy reads public Overwatch 2 career profiles by BattleTag and keeps everything else on the device — except for two features that only send anything while you use them.
- Followed players, sessions and settings live in local storage
- Rank alerts register your device with our notification server, so it knows which players to watch. Off by default.
- AI notes send the session's numbers to Google Gemini — never your BattleTag, never anything you typed. Pro only.
- Analytics and crash reporting stay off until you turn them on
- No advertising identifier is reachable on either platform
- Uninstall the app and the local data goes with it
Questions about Mercy
Is Mercy free?
Yes. Searching any BattleTag, full career profiles with ranks and KDA, the hero and map database, and following up to five players are all free, with no ads — as are rank change alerts. Mercy Pro is an optional subscription that adds rank history charts, the session tracker, player comparison, daily meta tier lists, AI notes on your sessions and patches, and a 50-player follow list. It can be cancelled in your store account at any time.
Do I need my Blizzard login?
No. Mercy never asks for a Blizzard account, an email address or a password. You type a BattleTag and Mercy reads that player’s public Overwatch 2 career profile. A profile set to private in the Overwatch 2 settings cannot be read by any tracker, including this one.
How is Mercy different from Overbuff or a web tracker?
A web tracker shows you a profile as it looks right now. Mercy is a phone app that keeps the history: it snapshots your career profile over time, so it can chart your rank per role and show the before and after of a single play session. It also works without an account and stores what you follow on the device rather than in a profile on someone else’s server.
How does the session tracker work?
You tap Start Session before you queue and end it when you stop playing. Mercy snapshots your career profile at both ends and shows the difference: games played, win-loss record, and the rank you gained or lost per role. A session you do not want counted can be discarded. The session tracker is part of Mercy Pro.
What do the AI notes do, and what do they send?
After a session, Mercy Pro writes a short read of it: what the numbers say and one thing to work on. There is a longer note across your recent sessions, and a briefing on what the newest patch did to the heroes you play. Only the numbers leave the device: games, win rate, KDA movement, rank changes. Your BattleTag is never sent, and neither is anything you typed. If the model is unavailable you still get the same summary, written by the app instead.
Can Mercy tell me when someone ranks up?
Yes, and it is free. Turn on rank alerts and Mercy notifies you when a player you follow moves up or down in competitive. It checks in the background, so the app does not need to be open. Enabling it registers your device and your followed players with the notification server; turning it off removes that registration again.
Which platforms and regions does Mercy cover?
Mercy reads both PC and console career profiles and shows them side by side, across the Americas, Europe and Asia regions. Competitive and Quick Play stats are both included, and the app itself is available in 15 languages.
What happened to Overbuff?
Overbuff sunset its Overwatch 2 service, so BattleTag lookups and hero win rates have to come from somewhere else now. Mercy covers the career profiles, the rank progression and the daily hero win rates as an app rather than a website.
How Mercy compares to OverbuffIs Mercy available on Android?
Yes. Mercy is on Google Play for Android and on the App Store for iPhone. Both read the same career data and share the same Mercy Pro features, except the home screen rank widget and the Siri rank shortcut, which are iPhone only.
What happens to my data?
It stays on your phone. Mercy runs no accounts and no user database, so followed players, recorded sessions, rank snapshots and settings are written to local storage on the device only. Nothing syncs between devices, and uninstalling the app deletes everything it stored.
Is Mercy made by Blizzard?
No. Mercy is an independent app and is not affiliated with, endorsed by or sponsored by Blizzard Entertainment, Inc. Overwatch® is a registered trademark of Blizzard Entertainment, Inc. Mercy reads publicly available career profile data and has no part in the game itself.
