CinderClock is a standalone desktop alarm clock for people who lose focus and sleep to their phones. It handles alarms, timers, and games on its own.

• Custom alarm patterns: Alarms can repeat every third day, run three days on and two off, or follow any rotation, and the clock holds the pattern until changed.
• Sunrise and sunset tracking: Enter coordinates once, and CinderClock works out local sunrise and sunset daily, so an alarm shifts with the seasons.
• A dismiss button you can’t miss: A 100 mm arcade dome handles wake-ups, and any alarm can require winning a game first, so snoozing takes real effort.
• No app, no account, no subscription: Every feature runs on the device, and open source firmware means the hardware can be repaired or modified.

With a timer, stopwatch, calendar, and nine arcade games built in, CinderClock replaces the phone on your nightstand.
