macOS: on first launch, right-click the app ā Open, then confirm.
What it does
Ranked pick suggestions
Champions scored on a win-rate-equivalent scale with SāF tiers, in three modes:
meta strength, matchup-focused, or balanced.
Matchups and synergy
Scores account for who the enemy already picked and who is on your team,
weighted by how much data actually backs each pairing.
Runes, items, skill order
The most successful setup for the champion and role you locked, taken from
real games rather than a hand-maintained list.
Reads champion select for you
Connects to the local League Client, so picks and bans appear as they happen
instead of being typed in.
Where the data comes from
Aggregated from Master+ ranked solo queue matches across EUW, KR, NA and OCE.
A scheduled backend job collects it twice a day. The app itself never calls
the Riot API ā recommendations are served from the pre-aggregated statistics.
Statistics reset on each patch, so recommendations track the current meta
rather than averaging across balance changes.
Privacy
No account, no sign-up, no telemetry.
Player identifiers are used only transiently while aggregating statistics;
nothing personal is stored or displayed.
The app reads champion select state from the local League Client. It does not
modify game files or interact with the game in any other way.
