Wavy is calm breaks of 2 to 5 minutes: guided meditations and breathing to be more present, find calm in your day, and sleep better. No accounts. No ads. Works offline. HOW IT WORKS Answer a short quiz and Wavy builds your daily routine: two or three short breaks placed at the moments that suit you best (waking up, mid-day, after work, before bed). Each break is a full-screen visual guide: a meditation that walks you through, or a circle that breathes with you — growing as you inhale, settling as you exhale. No decisions, no thinking: just follow. WHAT'S INCLUDED • Guided meditations: mindfulness, breath meditation, loving-kindness and gratitude, body scan, and a meditation for sleep • Guided breathing: deep sigh, box breathing, 4-7-8, coherent 5-5 and more • Body relaxation: release shoulders and jaw, tense-and-release, gentle shake, hand massage • Coming back to the present: 5-4-3-2-1 senses, panoramic gaze, humming • Night routines to get to bed without the mental spin • Slow, intentional morning starts • Color walk: the wheel picks a color and you go hunt it with your camera; your walks are saved • 5-7 day plans to build the habit step by step • Your progress in charts: daily calm, minutes of practice, streak and calendar • Every practice explains why it works — two lines, no fluff BUILT FOR PRIVACY Your sessions and check-ins stay on your device. No accounts, no profiles. We don't use your data for advertising. HONESTY FIRST Wavy doesn't promise miracles: these are simple meditation and breathing practices that work better the more you cultivate them. Wavy is a wellness app and is not a substitute for professional care. If you're struggling, please reach out for help. SUBSCRIPTION Wavy works with a subscription (monthly or yearly). Payment is charged to your Apple account and renews automatically unless cancelled at least 24 hours before the end of the period, in Settings > Apple ID > Subscriptions.
