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 THE GARAGE — 15 CAR ENGINES Free: American V8 · Turbo Straight-Six · Flat-Six Classic Pro: Flat-Six Redline · Flat-Six Track Spec · Flat-Six Apex · Flat-Six GT · Boosted Six · Stututu · Italian V12 · Supercar V12 · Italian V8 · Straight Pipe · Pops & Bangs · Anti-Lag Preview every engine in full quality before you buy.
