You're lying in bed. Eyes closed. But your brain is still at work. Replaying that meeting. Rewriting that email. Planning tomorrow. You know you should sleep - but your brain won't shut down. Sound familiar? You're not alone. 73% of professionals say they can't stop thinking about work at night. WorkBrain OFF is the first app designed specifically for this problem. -------------------- NOT MEDITATION. NOT A WORKOUT. -------------------- This isn't another meditation app that tells you to "clear your mind." If you could do that, you wouldn't need an app. WorkBrain OFF uses a 2-phase shutdown protocol that works WITH your restless brain - not against it. -------------------- HOW THE SHUTDOWN WORKS -------------------- PHASE 1 - Body Reset (7 minutes) Gentle movements that release the physical tension you don't even realize you're carrying. Neck rolls, shoulder releases, spinal twists. Your body has been holding your stress all day - this is where you let it go. PHASE 2 - Mind Off (8 minutes) A guided 4-4-6 breathing pattern with ambient sound designed to down-regulate your nervous system. Breathe in (4 sec), hold (4 sec), breathe out (6 sec). By the third cycle, your racing thoughts start to slow. Total time: 15 minutes. That's it. -------------------- WHY THIS ACTUALLY WORKS -------------------- - Your brain needs a "shutdown signal" Just like a computer, your brain doesn't turn off by itself. WorkBrain OFF creates a nightly ritual that trains your brain to recognize: work is over. - Movement before breathing Most relaxation apps skip the body. But physical tension keeps your mind alert. Body Reset releases it first so Mind Off can actually work. - It adapts to you The app personalizes your program based on your sleep quality, session history, and what keeps you awake. Every night gets a little better. - Built for consistency, not willpower Streak tracking, evening reminders, and morning check-ins create a habit loop that sticks - without requiring motivation. -------------------- EVERYTHING INCLUDED -------------------- - Personalized shutdown programs every night - 3+ Body Reset routines with guided cues - 7 ambient audio tracks for Mind Off - 4-4-6 breathing guide with visual pacer - Morning check-in: sleep latency, awakenings, fatigue - Progress dashboard with streak tracking - Adaptive difficulty based on your data - Works completely offline during sessions - Dark mode native - designed for bedtime - Available in English, Japanese, German, French -------------------- WHO THIS IS FOR -------------------- - You check Slack at midnight "just in case" - You rehearse tomorrow's meeting in bed - You've tried meditation but your mind won't sit still - You're exhausted but can't fall asleep - You want a simple routine - not another wellness app -------------------- START TONIGHT -------------------- Cancel anytime in App Store settings. Your workday deserves an ending. WorkBrain OFF is that ending.
