About

Couchette

Read full description

Tonight, take an overnight train. Couchette is a focus timer disguised as a European sleeper carriage. Choose a destination, choose how long you have, and let the rhythm of the rails carry you through the work. Your train only moves while you do. — YOUR JOURNEY PERSISTS — The cabin runs at real pace. If you have 25 minutes on a London–Inverness run, your train stops where it would actually be, somewhere south of Crewe — and tomorrow night you board again from that exact spot. A four-hour overnight can take a week of sessions. Your progress is a route, not a streak counter. — EIGHT HISTORICAL SLEEPER ROUTES — The Carpathian Night. The Trans-Siberian Reverie. The Nightjet over the Brenner. Each one hand-drawn from real timetables, with real stations crossed at the right moment in your session. Plus any destination on Earth. — THE COMPARTMENT — - A brass-framed window with a parallax landscape drifting past in real time - Rails, cabin creaks and rain on the glass - Station bells as you cross checkpoints - A passport that earns a stamp for every completed or partial journey - A conductor's log on arrival - Audio keeps running while your phone is locked — SESSION LENGTHS — 25 minutes for deep work. 45 for a study block. 90 for writing. Four hours for a full overnight. For writers, students, makers, and anyone who has wanted their focus time to feel like something other than a stopwatch. — MEMBERSHIP — Start with a 7-day free trial of Wagon-Lit Annual ($34.99/year). Monthly ($6.99/month) and Lifetime ($79.99) also available. Cancel anytime in App Store settings. The doors are closing. Step aboard.
