Chill Flows is a calm, ad-free ayurvedic wellness companion built around three gentle feeds — Mind, Body, and Soul. It's part social space, part daily-rhythm guide, part meditation library, all wrapped in a soft, unhurried interface that respects your attention. TAKE THE DOSHA QUIZ Answer a short set of questions and get a personalised reading of your Vata, Pitta, and Kapha balance. Your dosha shapes what shows up across the app — recommended yoga flows, meal-plan suggestions, mantra recommendations, and morning/evening routine tips. THREE FEEDS THAT BREATHE WITH YOU • Mind — thoughts, journaling prompts, quiet observations • Body — asana, food, sleep, movement, herbal notes • Soul — mantra, gratitude, seasonal ritual Filter by feed, follow the people whose practice you want to learn from, and build a timeline that's as calm as your morning tea. MEDITATIONS, MANTRAS & AMBIENT MUSIC Sounds is a growing library of guided meditations, Sanskrit mantras, and ambient music tuned for morning practice, focused work, and evening wind-down. Build playlists, schedule a track into your daily flow, and let the sleep timer fade you into rest. YOGA FLOWS BY DOSHA Vata-, Pitta-, and Kapha-tuned yoga sequences with clear pose cues and optional narration. Preview device voices, pick your favourite, and follow along without a screen between you and the mat. DINACHARYA — YOUR DAILY RHYTHM The Schedule page turns ayurveda's classical daily-rhythm framework into a simple, editable timeline. Add a morning meditation at 6:15, a golden-milk break at 15:00, a bedtime mantra at 22:00. Drop in meal-plan slots or slide in a yoga flow with one tap. Everything shows up as gentle reminders. MEAL PLANS & AYURVEDIC RECIPES Browse recipes filtered by dosha, meal category (breakfast, lunch, dinner, tea/tonic), and taste profile. Slot a whole day's plan into your schedule and follow it from your wrist. VISION BOARD A private collage space for the images, quotes, and intentions you're holding this season. Add, rearrange, and return to it whenever the day gets noisy. EVENTS & PLACES Find community classes, sound baths, retreats, and wellness spaces near you — or share ones you love. Every listing carries the host's dosha and practice so you can find teachers whose approach fits your rhythm. DIRECT MESSAGES Message practitioners, teachers, and other members privately. Mute, mark unread, and manage conversations with the same calm as the rest of the app. DESIGNED FOR STILLNESS • True dark mode with warm ink tones • Reduced-motion mode respected system-wide • Accessibility-first: high-contrast text, large touch targets, screen- reader-friendly navigation • Quiet-hours push settings so notifications never intrude on rest PRIVACY Your dosha, your journal entries, and your daily rhythm belong to you. We don't sell data. We don't run behavioural ads. Read the full policy in Settings → Privacy. Chill Flows is a wellness companion, not medical advice. Always consult a qualified practitioner before making changes to diet, sleep, or exercise.
