Features

Live match scoreboard

An overlay window above the game with the scoreboard of the current match. Data comes from the official Live Client Data API that the game provides locally — only what the player can already see in the game.

Lobby player profiles

Rank, champion mastery and a play-style summary based on each player's past matches, via the Riot Games API.

Build advice for your champion

Runes, summoner spells, items and skill order for your champion, based on statistics of ranked matches.

Runes and spells applied only on click

A suggested rune page and summoner spells are sent to the League client only when the player clicks the button. Nothing is changed automatically.

Match history

Your recent matches with details.

What Sintence does not do

It does not show hidden information about opponents: no cooldowns, timers or positions.
It does not act on behalf of the player.
It does not inject into the game process and does not read its memory.
It respects streamer mode: players hidden by the client are not revealed; their profile is shown as “Profile closed”.
