## What is Ko?

A simple app to help you focus on your breathing.


• A gentle on-screen guide expands and contracts in time with your inhale, hold, and exhale.
• You can freely adjust the length of each phase (inhale / hold / exhale).
• There are no accounts or data collection features.


This app is built around one idea: the breathing guide — the core of the experience — should stay open to anyone.
Core features such as the breathing animation and custom rhythm settings are available regardless of whether you ever pay for anything.

On top of that, optional “extra” elements such as visual customization or additional guides may be offered as paid add-ons in the future, for those who want more.

The goal is a quiet breathing tool that does not depend on ads or subscriptions.
