Perretro Clock is a highly customizable timekeeping app that allows you to change how time is displayed, measured, and experienced.

At its core, Bareface is a clean and full-screen clock that prioritizes simplicity and clarity. It includes both analog and digital displays, with the option to show or hide specific elements like clock hands, second markers, and digital overlays. The clock is designed for everyday use, yet offers features that go far beyond the standard.

One of Perretro Clock’s most powerful capabilities is the ability to redefine how time itself works. You can adjust how many seconds are in a minute, how many minutes make up an hour, and how many seconds define a full day. This allows you to create your own time system—whether for sleep cycle experimentation, productivity tracking, creative projects, or personal routines that don't align with conventional time.

In addition to the clock, Perretro includes a stopwatch and countdown timer, giving you essential tools for measuring intervals, tracking tasks, or managing time-based goals. These tools are built directly into the interface and can be toggled on or off depending on your needs.

You can also personalize the visual appearance of your clock. Choose from a curated set of background images, customize color schemes, and change the look of individual elements such as hour hands, minute hands, second hands, numbers, and more. Save your settings as profiles so you can quickly switch between different designs and setups.

All preferences are saved automatically and persist between sessions. The app does not require an internet connection or user account to function. Everything is handled locally and privately.

Perretro Clock is designed for users who want a personalized, precise, and flexible way to manage and experience time—whether for everyday simplicity or for exploring something entirely new.
