League of Legends is one of the most data-rich games in the world. Every match produces a mountain of stats—damage dealt, vision score, gold per minute, and more. Add in champion win rates, team compositions, and patch updates, and it’s easy to get overwhelmed. Whether you’re analyzing gameplay or just starting out with a LoL lvl 30 account, the sheer volume of information available can be both a challenge and a powerful tool for improvement.
That’s where companion apps come in. These tools help you make sense of all the data and even use AI to offer real-time advice, post-game reviews, and personalized improvement tips.
Here are five of the best League of Legends companion apps powered by data and AI:
1. Mobalytics
Best for: In-depth player performance analysis
Mobalytics stands out for its detailed, personalized performance breakdowns. It analyzes your gameplay using a “GPI” (Gamer Performance Index), which scores you across categories like farming, vision, aggression, and survivability. The app doesn’t just give you numbers—it explains what they mean and how to improve.
AI comes into play through tailored coaching suggestions and automated post-game analysis. For example, if you consistently lose lane as a midlaner, Mobalytics can point that out and offer practical tips like better trading patterns or ward placement.
The app also offers champion recommendations based on your playstyle and stats, which can be helpful when you’re stuck in a slump or want to try something new.
2. Blitz
Best for: In-game overlays and real-time insights
Blitz integrates directly with your League client and gives live, in-game overlays. It pulls champion data, matchup stats, and runes when you enter champion select. Once you’re in-game, it tracks CS per minute, gold differences, and ward placement—comparing your performance with averages at your rank.
Its AI-driven suggestions are subtle but smart. For instance, it may recommend changing your build path mid-game based on the enemy team’s itemization. Blitz also adjusts its pre-game recommendations based on patch updates and current meta data, so you’re always in line with what’s working.
Blitz is a solid choice if you like having an assistant without having to alt-tab constantly.
3. Porofessor
Best for: Match scouting and lane matchups
Porofessor is like having a scout for every match. As soon as your game loads, it breaks down your team’s and the enemy’s ranks, win rates, and recent performance. It even calls out “tilters”—players on a losing streak—and highlights smurfs, duo queues, and OTPs (one-trick ponies).
Porofessor uses AI to surface relevant patterns. If your opponent is on a five-game win streak with Zed, the app flags it. During the game, it tracks cooldown timers and objective spawns, helping you keep the pressure where it matters.
It doesn’t have as much post-game analysis as Mobalytics, but Porofessor is strong for pre-game prep and real-time awareness.
4. U.GG Desktop App
Best for: Streamlined performance with minimal clutter
U.GG made its name with fast, no-frills web-based stat tracking, and its desktop app follows that same idea—clean, efficient, and reliable. It provides build recommendations, tier lists, and matchup tips, all based on high-volume ranked data. The app updates automatically with new patches, so it stays meta-relevant.
The AI side here isn’t flashy, but it’s practical. U.GG sorts champion builds based on win and pick rates, not just popularity, so you’re more likely to land on builds that work at your skill level. It also lets you track your ranked progress over time and compare it with friends.
If you want insights without too much noise, U.GG is a great pick.
5. Facecheck
Best for: Draft strategy and team composition
Facecheck goes deep on team strategy. It analyzes champion synergies and team balance (AP vs. AD, engaging tools, scaling) and offers draft suggestions based on current pick/ban trends. Its AI looks at your team’s draft as it develops and highlights potential weaknesses before the game starts.
It’s especially useful for solo queue when you’re the last pick and need to plug a hole—like grabbing an AP jungler or tank support. In-game, it offers similar overlays to Blitz, but with more focus on big-picture strategy than just personal stats.
Facecheck offers some feedback post-game, but its real strength is in draft planning and macro decision support.
Final Thoughts
All five of these companion apps bring something valuable to the table. If you want to improve your mechanics and get personalized coaching, Mobalytics is your best bet. For live, in-game support, Blitz and Porofessor do a great job. U.GG is a clean, data-first option for players who hate clutter. And if you like thinking like a coach and winning the draft, Facecheck has the tools for that.
None of these apps will magically make you a better player overnight. But used well, they can help you spot bad habits, make smarter decisions, and climb with more confidence.
And in a game where every second—and every decision—counts, that edge can make all the difference.
