Pulse Sleep - Description - For sleepless nights and moments when your mind won't settle. "Pulse Sleep" is a support app designed to regulate your autonomic nervous system through breathing rhythms and soothing vibrations (haptics). Tonight, why not transform your smartphone from something that disrupts your sleep into something that helps it? Rediscover your natural rhythm and regain your calm with Pulse Sleep. No need to stare at a screen. Simply hold your smartphone and breathe in sync with the gentle vibrations pulsing from your palm. By blocking out visual distractions and turning your focus inward, you can guide yourself into a state of deep relaxation or heightened focus. 【Recommended For】 • You lie in bed but can't stop your racing thoughts. • You feel your breathing becoming shallow due to anxiety or stress. • You want to calm your nerves before an important meeting or interview. • You need to quickly enter a "focus mode" before work or study (Great for those with ADHD traits). 【Key Modes】 1. Relax (4-7-8 Breathing) Uses a technique designed to activate the parasympathetic nervous system. It soothes anxiety and helps induce smooth sleep. Highly recommended when you feel signs of a panic attack or high levels of stress. 2. Focus (Box Breathing) Uses the "4-4-4-4" rhythm to activate the brain. This method is used by Navy SEALs and is perfect for maximizing performance during work or study sessions. 3. Balance (Coherent Breathing) Uses an equal breathing rhythm to restore harmony between mind and body. Ideal for a quick daily break or an emotional reset. 【Features of Pulse】 • Haptic Feedback: Unique vibration technology allows you to know exactly when to inhale and exhale, even with your eyes closed. • Minimalist Design: A dark-mode interface stripped of unnecessary elements to enhance immersion and reduce eye strain. • Privacy First: No account registration required. All data is processed and stored locally on your device.
