Idle game · Coming soon to Google Play
Send a pulse into the dark. Someone answers.
Echo: Idle Incremental is a calm game about one glowing signal that grows into a living constellation. You tap first, then automate everything, and it keeps going while you are away.
In preparation. Not in the store yet.
- Free to play
- Plays offline
- Ads only if you choose
- Ages 18+
Four colours, four layers.
Every layer of the constellation has its own colour, its own tree and its own rhythm. You decide when to go deeper.
Pulse
Tap the core and hit the resonance ring for a stronger pulse. You build your first relay within the first minute.
Echo
Reset the run and keep permanent power: every Echo you ever earned raises production.
Harmonic
The second layer resets your Echoes and gives you its own tree with stronger bonuses and head starts.
Chorus
The third layer, with its own upgrade tree. It keeps Echo showing you something new after weeks of play.

Echo is a game, not a learning app. It is made for adults and is one of the projects I build for the joy of making games.
Frequently asked questions.
What is Echo?
Echo is a minimalist idle and incremental game. You start with one glowing dot and a tap, build relays that produce Signal for you, and reset into permanent upgrades. The numbers grow into a constellation.
Does Echo keep progressing when the app is closed?
Yes. Your relays keep working while you are away, and you come back to a summary of what they earned. The game itself needs no internet connection.
How do the ads work?
Echo has no banners, no pop-ups and no energy timers. The only ads are optional reward videos that you start yourself, for example to speed up time. The whole game can be played without them.
What can I buy?
There is one optional one-time purchase, the Amplifier, which doubles your production for good. It is not a subscription. Nothing else that affects progress is sold, and you see the price in Google Play.
Do I need an account?
No. Your progress is stored on your device. Backup codes let you move it to a new phone.
What data does Echo process?
Where the law requires it, Google asks for your consent once, before ads and analytics. Without consent there are no ads and no analytics, and the game stays fully playable. The privacy policy lists every service.
Who is Echo for?
Echo is made for adults who enjoy idle and incremental games. It is not a learning app and not aimed at children.
