About
Your alarm doesn't beep. It starts.
ColdStart replaces the soulless beep-beep-beep with a cold engine cranking to life inches from your ear. Every alarm is a real engine recording built as an escalation: cold start and idle first, then climbing revs, then full redline with the limiter bouncing — and it loops until you deal with it.
HOW A COLDSTART MORNING WORKS
• Your engine cold-starts at the time you set — delivered by iOS's native alarm system, so it rings on the Lock Screen even with the silent switch on
• Snooze is a Pit Stop: the engine cuts, a 9-minute countdown runs on your Lock Screen and Dynamic Island, then it re-fires
• Cut Engine ends the session — until tomorrow
