Tock Flap

There was a time when train stations announced the next departure with a clatter of flipping panels, a cascade of little black cards turning over, each one a beat of mechanical music. Tock Flap brings that feeling to your Playdate.

What it is

Tock Flap is a countdown timer you set the old-fashioned way. Roll the crank between your fingers and feel the minutes tick by, one notch at a time, with a soft click for every step. Press start, and watch them fall away on four big split-flap cards. Every flip lands with a satisfying click and a low thunk you can feel.

It's a small piece of analog joy on a tiny yellow handheld.

How it works

• Turn the crank to dial in 00 to 99 minutes, just like an old kitchen timer. Each minute is a tiny detent under your thumb.
• Press A to start. The cards begin their countdown.
• Press A again to pause. The display breathes gently while you're away.
• Press B to cancel and return to the dial.

You can also use the d-pad. Hold Up or Down to scroll faster and faster across the dial.

Features

• Hand-tuned animations. The cards fall with gravity, bounce on landing, and even quiver on the way down, the way a real split-flap board does.
• Crafted sound. Each flip is a layered click and thunk. The final alarm is a single confident pip.
• Dark or light mode. Switch between the classic black-on-white station look and a softer inverted theme.
• Remembers your last time. Pick up right where you left off.
• Stays awake while counting. Your Playdate won't auto-lock mid-timer.
• Made with care. Every spacing value sits on a 4-pixel grid. Every animation curve was tuned by hand. It's a small app that wants to feel exactly right.

Built for the kind of waiting worth listening to.
