About this app

Your echoes are your teammates. ECHO is a time-loop puzzle: every run is recorded, and when you press ECHO, your past self replays it - step by step, loop after loop. Hold plates for each other, open doors across time, and thread paths no single runner could ever take. EASY TO LEARN, DEEP TO MASTER - 100 campaign levels across ten decades, from gentle first steps to choreographed finales - Mechanics that weave together: chained doors, counter-doors, double doors, fragile floors, beat walls, paradox boards and mirror echoes that replay your run backwards - Handcrafted signature levels where every single step must be planned FOUR WAYS TO PLAY - Campaign: 100 levels with a carefully tuned difficulty curve - Daily puzzle: one fresh board every day - keep your streak alive - Zen: endless generated puzzles in six difficulties - Time challenge: how many boards can you solve in one run against the clock? MADE WITH CARE - Completely offline: no account, no ads, no tracking, no data collection - Music is synthesized live on your device - no two sessions sound the same - Home-screen widget that grows with your streak - and hides a secret level - Game Center leaderboards and achievements - Available in 7 languages ECHO is free and complete from the first minute. The only purchases are voluntary tips for the developer - they unlock nothing. Your past self is waiting.
