Hi everyone! SINO began from a simple frustration: even when I was working hard, I wasn’t always working on the right things. One day, a podcast described how most of our daily effort is consumed by “noise,” and how real progress happens when we stay aligned with just a few meaningful “signals.” That idea stayed with me — and eventually grew into the core philosophy behind SINO. While building this, my goal was to create more than a timer. I wanted a tool that helps you lock onto what truly matters, filter out distractions, and move toward your goals with clarity and intention. Throughout development, SINO evolved from a simple focus tool into something closer to a personal performance OS — and this is still only the beginning. What matters most now is listening. I’m committed to hearing from users, adapting quickly, and improving SINO in ways that genuinely help you work better and live better. If you have feedback or ideas — big or small — I’d love to hear them. SINO is currently available in South Korea, the United States, Canada, and Singapore, and we’ll continue expanding as we grow. Thanks for checking out SINO. I’m excited for what we can build together.
