Monochron – 3D Puzzle Clock
Unique typographic exploration
$4.99
Time told in cubes. Every digit is a solved state, and every minute is an honest sequence of turns you could repeat on a real cube.
Monochron is a clock made from three-dimensional puzzles, whose colors have been reduced to black and white. It is a journey into the exploration of the expressive possibilities of the structural grids of these puzzles, where each digit is the best version of itself, achieved with the minimal means of the puzzle tiles and their transformations.
As a result, the digits take on peculiar and eccentric shapes while remaining legible.
The cubes have three black and three white sides. Every transition is executed with integrity and can be physically replicated on a real cube, adding to the uniqueness of both the concept and its execution.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Fixed an issue where the clock could start up sideways and stay that way
until the app was restarted.
The clock now follows the phone even when Portrait Orientation Lock is
turned on in Control Centre.
Rotation is smoother: all four digits now turn together, and orientation
is picked up at shallower angles, so the clock works properly on a stand.
