You pick up your phone to check the time. Somehow, 40 minutes of Instagram later, you're still on the couch. Sound familiar? Focus Lock breaks that loop — automatically. HOW IT WORKS The moment you plug in your charger, Focus Lock locks the apps that waste your time. No willpower needed. The trigger does it for you. Want back in? Solve a quick math challenge first. Your brain has to actually engage before you can scroll again. That's it. Simple. Surprisingly powerful. THREE WAYS TO LOCK Charging Lock — Plug in and apps lock automatically. Most people charge 2–3 hours a day. That's 2–3 hours you could be present. Low Battery Lock — Battery below 30%? Instead of doomscrolling on your last 10%, Focus Lock locks distractions automatically. Manual Focus Sessions — Start a 15-min, 30-min, or 1-hour session anytime. Lock your apps, set your timer, get to work. WAYS TO UNLOCK Every other app lets you tap "ignore" and keep scrolling. Focus Lock doesn't. Solve to unlock — a quick math challenge in Easy, Medium, or Hard. Easy ones take 5 seconds. Hard ones make you think. That tiny bit of friction is enough to break the reflex — and ask yourself if you actually want to open that app. Walk to unlock — don't want to think, want to move? Earn your way back in with steps instead, from as few as 10 up to 5,000. On by default, and it works even from your pocket. Strict Mode removes the give-up button on challenges entirely — solve it or stay locked. Most of the time, you won't even want to. BATTERY CARE Focus Lock also pays attention to what it's plugged into. See how healthy your daily charging habits look, and get a nudge the moment it's actually fine to unplug — usually around 80%. FOCUS INSIGHTS Focus Lock tracks your own focus sessions, locally on your device, and turns them into something useful. "You've locked in 3 times today — above your weekly average." "Most sessions start after 9PM. Worth a bedtime nudge?" "Best focus day this week: Thursday. Keep it up." Friendly nudges, not guilt trips. You decide what to do with the information. FEATURES Auto-lock apps when charger is connected. Auto-lock apps when battery drops below your threshold. Manual focus sessions (15 min, 30 min, 1 hr, or custom). Math unlock challenges in Easy, Medium, and Hard. Walk to Unlock — set any step goal. Strict Mode with no give-up option on challenges. Battery Care and unplug suggestions. Configurable safety release, so an open-ended lock never traps you for good. Smart daily suggestions based on your own focus patterns. Focus streak tracker. Weekly progress report. Your data never leaves your device. SUBSCRIPTION PRO — unlock everything. $1.99 per week or $19.99 per year (save 79% — best value). Pro includes unlimited app locks, Low Battery Lock trigger, all challenge levels and Strict Mode, full analytics dashboard, daily smart suggestions, and streak system with achievements. Subscriptions are billed through your Apple ID and auto-renew unless cancelled at least 24 hours before the end of the current period.

We never see which apps you use, what you type, or what you view. All data stays on your iPhone. Always.

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.
