Hi Product Hunt! 👋

I'm Petr, the solo developer behind Blinkky.

The idea started as a question: what if the only input in a game was a blink? It turned into a full arcade game – you guide a little owl through seven worlds and every deliberate blink is one flap of the wings. Your hands stay free and the phone can rest on the table.

A few things I cared about:
• Privacy – face detection runs entirely on the device (Google ML Kit). No camera frame is ever uploaded or stored.
• Comfort – normal involuntary blinks are ignored, a 10-second calibration adapts to your eyes (glasses too), and air currents regularly carry the owl so you can rest your eyes.
• Fair leaderboards – every run is replayed on the server from its inputs, so scores can't be faked.
• Fun with others – a two-player mode where two faces share one phone, plus duels via a link.

It's free with no ads and no purchases; everything cosmetic is earned by playing. Android only for now.

Transparency: I built it with heavy help from an AI coding assistant. The game itself doesn't use generative AI while you play.

I'd love your feedback – especially how blink detection works on your phone in different light. Thanks for checking it out! 🦉
