Choose which apps, categories and websites to limit. Every feature in RLX is free, with no subscriptions, paywalls, ads or account required. When you want to unwind, breathing, meditation, journaling and sleep sounds are there for you. YOUR APPS, YOUR BOUNDARIES Choose apps, categories and websites with Apple Screen Time. Block them now, set a daily limit or plan quiet hours. See your agreements together in your day view. Take a brief pause before opening selected apps, or choose a stronger temporary lock. Use the heart to save your favorite breathing, meditation and movement practices. In Your exercises, you’ll find them alongside exercises you’ve recently completed. Your favorites also help shape suggestions in Today and Rest. More room for your thoughts. Type or dictate your notes. Add your own topics and a photo, then revisit everything in Overview. Your journal can be included in your automatic iCloud copy, without syncing. MY EVENING My evening remembers your exercise, favorite sound and sleep timer. Settle in with breathing, a body scan or one of two new visualizations narrated by your chosen iOS voice. Then let the sound continue with your screen locked. Brief guidance is there if you wake in the night, too. In the morning, record how you slept, alongside your sleep recording and available stages from Apple Health if connected. A MOMENT OF CALM, YOUR WAY Take a minute for yourself. Breathe along, follow a short meditation or write about what's on your mind. Choose from 17 breathing rhythms and 18 short text-guided meditations. Make time for a simple movement exercise or a short walk, too. Find what feels right for you today. AGREEMENTS FOR YOUR FAMILY Child Mode gives your child a calm home with breathing and quiet moments. A parent manages the agreements on the child's device with a local PIN. AT HOME ON IPHONE AND IPAD Use the spacious iPad layout or keep a small moment of calm close on iPhone. Light and dark appearances follow your preference. Widgets, Control Center and Shortcuts bring your choices within reach. Saved on your device. With iCloud backup enabled, your journal can also be stored in your own iCloud.
