Every time you wake your Mac, a puzzle appears. No app to open, no reminder to dismiss. Just one tactic standing between you and your desktop - and a rating that climbs while you're not even trying.
What steady practice looks like.
You already unlock your Mac dozens of times a day. What if each one made you a stronger chess player?
ChessUnlock turns an action you can't skip into practice you'll never forget. No discipline required - it's already part of your day.
Open your laptop or tap a key. Instead of your desktop, a chess tactic appears fullscreen.
Find the winning move. Puzzles match your rating - always challenging, never impossible. Takes 5-10 seconds.
Your Elo rating adapts. Your pattern recognition sharpens. You improve passively, every single day.
Habit stacking - attaching a new behavior to an existing trigger - is one of the most effective ways to build lasting habits. Research shows roughly 40% of daily behavior is habitual, running on autopilot without conscious decision-making.
ChessUnlock uses the one action you never skip - waking your computer - as the trigger for daily chess practice. You don't need motivation. You don't need to remember. The habit just happens.
"The most effective way to build a new habit is to pair it with an existing habit. You already do things every day without thinking. Attach your new behavior to one of those actions."
