FastClock makes time move faster. Change how you perceive time. Focus more. Get more done. FastClock is a unique clock and timer app that changes how time feels. By making time move faster, it helps you stay focused and increase the density of your working time. Features • A clock and countdown timer that run faster at your chosen speed • Adjustable speed (unlockable) • Digital and analog clock views • Clean, distraction-free design Notes • Timer sound plays only while the app is in the foreground. • Changing the speed requires an in-app purchase (free version uses a fixed speed). • This app does not change your device’s system time. Time runs faster only within the app.
