Focus Rail is a focus timer that turns work and study sessions into train journeys across real railway routes. Choose a starting station, set a session length, and board your train. As you stay focused, your route moves forward on the map. It is a simple idea, but it makes a plain timer feel much more alive. Focus Rail is built for people who want more than a countdown: • Start study sessions with a clear ritual • See progress through a moving train and live route • Use Pomodoro style sessions or longer deep work blocks • Keep active sessions visible with Live Activities • Review past trips and build a routine you can stick with • Add ambient sound when you want a calmer workspace What you can do: • Pick an origin station and travel to real destinations • Set short study bursts or long deep work sessions • Follow your journey on the map in real time • Use optional screen controls when you want fewer distractions • Check trip history and session stats • Choose map styles that match your mood • Get reminders to start your next session Focus Rail works well for study, reading, writing, coding, exam prep, and quiet solo work. If Pomodoro timers feel too flat and traditional focus apps feel too cold, this gives you something more motivating without getting in your way. Focus Rail Pro unlocks more map styles, full trip history, Live Activities, and extra ways to stay on track. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
