Here’s a real ladder game — Protoss vs Zerg on Tourmaline LE — after the desktop app read the replay. Both build orders, both strategies, and the result. None of it was typed in by hand.

And it stacks up over time
A few games in, the graphs do the talking.
Every game you finish feeds the same stats pages: win rate week by week with a rolling average, your MMR climb, the matchups and maps you’re strongest on, and how your build mix shifts — plus per-build and per-opponent breakdowns.
The desktop app does all of this after every game you finish — no tagging, nothing to upload. And the OBS overlay flags a familiar opponent the moment they load in.
What you get
Seven tools, all fed by your replays.
Finish a game and your replay is read automatically. Everything here works off that same data — no tagging, nothing to upload yourself.
