UP! is a native macOS companion for League of Legends. It tells you what to pick and why, imports your runes and build, scouts the lobby and keeps the timers while you play.
Free. For macOS 14 Sonoma and later, on Apple silicon and Intel.
From the moment the queue pops to the post-game screen, UP! does the busywork in the background and puts the one thing you need in front of you.
in queue
Grab a drink while you queue. When a match pops, UP! plays a sound, bounces its Dock icon and accepts for you two seconds later, in every queue including Swiftplay.
to pick
The assistant opens with champ select. Every champion you own gets a score out of 99 for your role, with the reasons spelled out: how it does against the enemies revealed so far, your mastery and recent games, and the damage your team is missing.
in game
The HUD sits on top of League in windowed or borderless mode: Dragon, Baron and inhibitor timers, every enemy's level and items with counter items outlined, your build path, the gold left to your next item and which skill to level next.
victory
Every game gets a grade from S+ to D for your KDA, kill participation, damage, deaths, farm, vision and objectives, measured against the other nine players. LP is saved after each ranked game, so today's climb and the week's are one glance away.
Between games, four tabs hold everything else: profiles for any player, builds for every champion and mode, the tier list for your region and rank, and a toolbox for the client.
UP! speaks ten languages and switches between them without a restart.
UP! is free. It needs macOS 14 Sonoma or later and the League client installed. One build runs on Apple silicon and Intel.
Prefer to build it yourself? Clone the repository and run ./scripts/build-app.sh with Xcode 16 or later.
UP! is written in SwiftUI as a native Mac app. It sits in the menu bar, follows the League client you are already signed in to and steps in at the four moments where players usually reach for a stats website: the ready check, champ select, the game itself and the post-game screen.
It is meant for anyone who plays League of Legends on macOS and wants pick advice, imported runes and objective timers without switching to a browser mid-lobby. Ranked players get LP tracking and grades measured against the other nine players in the match. ARAM players get their bench ranked, Arena players get suggestions that account for their duo, and anyone can look up a profile on any server.
UP! gets its data from two places. Your own games, mastery and lobby come from the League client's local API (LCU) and, during a match, from Riot's Live Client Data API. Build statistics, tier lists and profiles on other servers come from op.gg's public statistics. You do not need a Riot API key or an UP! account.
Download the latest .dmg, drag UP! into Applications and allow it once in System Settings, Privacy and Security. It adds itself to your menu bar.
When a match pops, UP! plays a sound and accepts two seconds later. Change the delay or turn it off in Settings, or accept by hand with ⌘ ⇧ A.
The champ select assistant opens by itself and scores every champion you own out of 99 for your role, with the reasons. Lock in and your runes, summoner spells and item set are already in the client.
Run League in windowed or borderless mode to see objective timers, enemy items and the gold left to your next item. ⇧ Tab opens the match overview.
Every game gets a grade from S+ to D against the other nine players, and ranked games save your LP so you can follow the day's and the week's climb.
Yes. You download it from GitHub Releases at no cost. There is no UP! account to create and no Riot API key to enter: it works with the League client you are already signed in to.
Any Mac with macOS 14 Sonoma or later and the League client installed. One build runs on both Apple silicon and Intel Macs.
No. UP! only talks to interfaces Riot's own software exposes: the client's local API (LCU) and the Live Client Data API during a game, plus public statistics from op.gg. It never reads or writes game memory, never injects into the game and never touches Vanguard.
Only Riot decides that, so nobody can promise it. What UP! does is limited to things you could do by hand in the client: it does not pick or ban for you, does not reveal names the client hides in ranked champ select and never shows information the game hides from you. The LCU is not officially supported, so a client patch can change it.
No. It ranks the champions you own, explains each score and suggests bans, but you make every pick and ban yourself. What it can do on its own is accept the ready check and import your runes, summoner spells and item set once you lock in.
The build is signed ad hoc and not notarized by Apple, so macOS asks once. Open UP!, then click Open Anyway in System Settings, Privacy and Security. On macOS 14, right-click UP! and choose Open instead.
The HUD draws over League in windowed or borderless mode, so set the game's window mode to one of those. Control, Shift and H hide it whenever you want a clean screen.
Build statistics, the tier list, account search and profiles on other servers come from op.gg. UP! is not affiliated with op.gg. Your own mastery, recent games and LP come from your League client.
Ten: English, German, French, Spanish, Italian, Portuguese, Dutch, Polish, Czech and Slovak. You switch between them in Settings without restarting the app.
