Full disclosure before anything else: we build Hexgate, one of the six apps below, and we put it first. We have tried to keep every other entry honest anyway, including the cases where a competitor is simply the better choice, and we say plainly who should skip Hexgate. Each app in this list is the best in the League ecosystem at something, and the fastest way to pick is to figure out which something your gameplay is missing.

1. Hexgate - Best Adaptive In-Game Itemization
Ours, so apply salt. Hexgate exists because of the pattern you will notice in every entry below: every other tool recommends the aggregate build, the one computed across all games this patch, with no knowledge of who you are actually playing against. Hexgate reads the enemy team live and re-scores every viable item against their damage split, crowd control, healing, tankiness, and fed threats. Against four AD threats it moves armor up. Against a 7/0 Katarina it moves anti-burst up. Each adjustment is labeled with the reason, so you learn the counter-build logic instead of just copying it.
It is also the lightest app in this list: native Tauri/Rust, typically under 100 MB of memory, no Overwolf, no Electron, no ads. Counter-building is the one skill it automates, and it does nothing else.
As of August 2026 it is also the only overlay here with real ARAM Mayhem augment support: live S–D tier badges on the augment cards as they are offered, plus a Mayhem champion tier list in champ select.
The tradeoffs: no profiles, no ranks or full lobby scouting, post-game breakdowns and Lane Scouting (the early-game habits of your lane opponent and the enemy jungler) only in the Pro+ tier, Windows only, and the free tier is 3 games per day. If you want breadth, pair it with the OP.GG website or pick Blitz instead.
Why we would pick it over the rest
Every app below imports a build before the game and then goes quiet. Hexgate is the only one still making item decisions with you at 18 minutes, when the enemy Katarina is 7/0 and the aggregate build has no answer. If your losses come from building the same items every game, this is the leak to close first. If your losses come from drafting blind or repeating mistakes you cannot see, keep reading: Porofessor and Mobalytics are better at those.

Download Hexgate2. Blitz - Best All-in-One for Most Players
Blitz is the default answer when someone asks for "an app for League". Auto rune import, build suggestions, post-game stats, benchmarks, and coverage of multiple games in one package. It gets the fundamentals right with minimal setup, which is exactly what most players want.
The tradeoffs: it is an Electron app with a real memory footprint, the free tier carries ads and upsells, and its build recommendations are aggregate meta builds - the same for every player of your champion, regardless of the enemy team. Breadth is the product; no single feature is the deepest of its kind.
3. Mobalytics - Best for Improvement and Analysis
Mobalytics is the improvement platform of the group. Its GPI (Gamer Performance Index) breaks your play into measurable skills, and the post-game analysis is the most serious attempt in the ecosystem at telling you why you lost, not just that you did. If you treat ranked like a sport and want a training tool, this is the category winner.
The tradeoffs: the good parts sit behind the GG+ subscription, it runs on Overwolf (a second platform alongside League), and the in-game overlay itself is not the star - the analysis after the game is. Builds, again, are static aggregates. We compared it in depth in Hexgate vs Blitz vs Mobalytics.
4. Porofessor - Best Live Game Scouting
Porofessor answers one question better than anyone: who is in this lobby? Ranks, win rates, playstyle tags, loss streaks, one-tricks - surfaced automatically in champ select. Knowing the enemy top is autofilled or their ADC is smurfing changes real decisions, and Porofessor makes that information effortless. Backed by the League of Graphs team, the underlying data has a long track record.
The tradeoffs: it requires Overwolf, the free tier is ad-supported, and it is fundamentally an information tool: it tells you the enemy mid is fed, not what to do about it. Full breakdown in Hexgate vs Porofessor.
5. OP.GG Desktop - Best Stats Platform Integration
OP.GG is the reference stats site of the entire player base, and the desktop app moves that into the client: auto rune and build import in champ select, a Shift+Tab in-game overlay with builds, opponent data, and spell timers, plus TFT and Valorant support. Free, familiar, and the data everyone already argues from.
The tradeoffs: Electron footprint, ads, and every recommendation is a patch-level aggregate that ignores your actual lobby. Our full comparison: Hexgate vs OP.GG.
6. U.GG - Best Simple Build Imports
U.GG built its reputation on being the fastest, cleanest place to grab the highest win rate build and runes, and its app does exactly that with no ceremony. If your entire requirement is "give me the meta build without alt-tabbing", U.GG delivers it with the least friction of anything here, for free.
The tradeoffs: it is deliberately narrow - import and go. No scouting, no analysis, and the builds are the same static aggregates as everywhere else. Details in Hexgate vs U.GG.
How to Actually Choose
Ignore feature counts and ask what loses you games:
- You get outdrafted or surprised by smurfs: Porofessor.
- You repeat the same mistakes and cannot see them: Mobalytics.
- You just want the meta build and runes, fast: U.GG, or OP.GG if you also live in its stats pages.
- You want one app that covers the basics everywhere: Blitz.
- You build the same items every game no matter the enemy comp: Hexgate - that is the leak it exists to close.
On performance: everything Overwolf-hosted or Electron-based costs a browser engine of RAM. With 16 GB or less, pick one heavy app at most, or pair light tools that each do one job.
Safety, Briefly
All six apps operate within Riot's third-party tool policy: public data and Riot's local APIs only, no memory reading, no injection, no input automation. None of them will get you banned. The tools that do are the ones promising scripting or automation, and none of them are in this list.
Deciding between two specific apps? We have head-to-heads for the pairs people search most: Porofessor vs Blitz and Mobalytics vs Porofessor. Leaving one of them? See the Blitz alternatives, Mobalytics alternatives and Porofessor alternatives roundups, or the list of LoL overlays that run without Overwolf.
