About Echo: Idle Incremental
Echo is a calm, minimalist idle game for everyone who loves incremental games. Tap to start, build relays that work for you, prestige for permanent power and keep progressing offline. The numbers climb from a handful to astronomical, and every reset makes the next run faster.
WHY IDLE PLAYERS ENJOY ECHO
• Deep prestige: three layers (Echoes, Harmonics and the Chorus), each with its own upgrade tree
• Real offline progress: your relays keep earning for up to 12 hours while the game is closed
• Full automation: relay autobuyers, auto-Echo and auto-Harmonic rules let the game play itself
• No forced ads: no banners, no pop-ups, no energy timers. Ads are optional rewards you start yourself
• Plays without an internet connection. No account, no login
HOW IT PLAYS
• Tap the core to send pulses, and time your taps with the resonance ring for a stronger pulse
• Build eight tiers of relays. Each tier produces the one below, so production snowballs
• Reset into Echoes when growth slows, spend them on permanent upgrades and go further
• Pick Frequency cards that change every run, and beat Silence challenges for lasting rewards
MORE TO DISCOVER
• A quiet, hopeful story told in 94 short transmissions, collected in your Archive
• A daily gift that grows over seven days
• 75 achievements, each with a small permanent bonus
• Huge numbers in short, scientific or engineering notation
CALM BY DESIGN
• Dark, minimal space visuals and generated music that grows with your constellation
• Reduced-motion and low-power modes for long idle sessions and a happy battery
• Backup codes to move your progress to a new phone
• Nine languages
FAIR PURCHASES
Everything in Echo can be reached without paying. There are two optional one-time purchases and no subscription: the Amplifier doubles your game speed for good and lets time away count for 24 hours, and Clear Signal gives you every ad reward without watching an ad.
Short sessions or long idle stretches: Echo rewards both.

User reviews
Fantastic idle/incremental game with accurate offline progression and extremely easy to use interface. Only bug I've encountered so far is on one rules for echos; it won't let me scroll the list of possible choices for each automated echoing. Other than that, I do like the new UI design, though it might take a bit t...
