Competitive League of Legends is a game of details. From jungle timers to CS tracking and damage analysis, the difference between winning and losing often comes down to information. That’s where overlays come in.

Overlays are tools or applications that display additional data on your game screen or second monitor. For casual players, they can be fun quality-of-life upgrades. For competitive players, they’re game-changers — helping track matchups, objectives, and performance in real time.

In this article, we’ll dive into the best overlays for competitive play in 2025, explaining how they work, why pros and high-elo players use them, and how you can integrate them into your setup.

1. What Are Overlays in League of Legends?

An overlay is any visual layer of information added to your gameplay. It can be:

• A desktop app overlay that shows runes, builds, and timers.
• A streaming overlay for Twitch or YouTube.
• A performance overlay tracking FPS, ping, and PC health.

For competitive play, overlays usually mean statistical and in-game assistants like Porofessor, Blitz, or Mobalytics.

2. Why Overlays Matter in Competitive Play

• Efficiency: Save time by auto-importing builds and runes.
• Awareness: Track summoner spell timers or jungle camps.
• Preparation: Scout opponents in champ select.
• Improvement: Post-game analysis for weaknesses.
• Consistency: Stick to optimal builds without second-guessing.

High-elo players and streamers use overlays because every second counts.
