Tempo

Live win chance, item options and objective swings for your League games, on your phone.

Download for Windows

Windows 10 or 11. Free. About 5 MB. No account.

  1. Download and run it

    Edge may say the file "isn't commonly downloaded". Click ..., then Keep, then Keep anyway.

    Windows may show "Windows protected your PC". Click More info, then Run anyway. Tempo is a small app made for a few friends, so Windows does not know it yet.

  2. Scan the code

    Tempo opens with a QR code. Point your phone camera at it and open the link. On iPhone, tap Share, then Add to Home Screen.

  3. Play

    Tempo starts with Windows and waits in the tray. When a game starts, the board shows up on your phone by itself. Updates are automatic.

Good to know

Tempo reads only the game's own local data (the Live Client Data API on your PC). It does not read game memory, draw over the game, or press keys. It shows options with numbers, never orders.

Riot may consider a live win chance as information a player would not otherwise have. Use it knowing that.
