Focus Train turns your productivity sessions into beautiful, scenic railway journeys. It is designed for students, deep workers, and dreamers who need an escape from distractions to find their flow. It has 3 primary features: - Immersive Focus Journeys: Transform your timer into a travel experience. Watch your train traverse real-world satellite landscapes as you work, with every minute bringing you closer to a new destination. - Ambient Soundscapes: Block out the noise with dynamic, high-quality audio environments. Choose from the rhythmic clatter of Train wheels, calming Raindrops, deep Ocean waves, or a peaceful Forest. - Gamified Progress: A tracking system that feels like a travel log. Record every trip in your history, track your total distance, unlock new stations, and earn medals as you master your focus. Cinematic Views: Switch between a detailed satellite map or an immersive "Window" mode to watch the world go by. Premium Aesthetics: A stunning, gesture-driven interface with liquid-glass effects, haptic feedback, and fluid animations. Privacy First: Your journey data and habits are stored locally on your device, respecting your privacy. Focus Train is a unique alternative to Forest, Flora, and generic Pomodoro timers for those seeking a more atmospheric and relaxing path to productivity!
