Understand each night in detail, discover your long-term patterns, and shape a sleep experience that responds to you.\n\nTRACK YOUR SLEEP, BODY, AND ROOM\nTrack sleep duration, stages, awakenings, movement, and sleeping positions. With DUVA ONE, follow heart rate, heart rate variability (HRV), and bedroom noise, light, temperature, and humidity. View changes throughout the night alongside your sleep timeline to see how your body and surroundings relate to your rest.\n\nDISCOVER YOUR RHYTHM\nRhythm identifies recurring patterns in your sleep timing, duration, and naps. See which nights share a pattern, when it tends to appear, and the sleep and body signals associated with it. Explore connections with your recorded routines and follow how your patterns emerge and change as your sleep history grows.\n\nPERSONAL SUPPORT WITH DUVA AI\nStart a conversation about your sleep, how you feel, or the support you need. Ask for breathing exercises, meditation, relaxation, or bedtime guidance.\nWhen enough data is available, the Agent can also use your patterns and current state to provide proactive support, including audio and noise relief adjustments with DUVA ONE. \n\nFIND THE SOUND FOR YOUR MOMENT\nChoose white noise, brown noise, sleep sounds, meditations, and guided sessions. With Fingertip Soundscape, combine sounds, adjust their positions and volume, and save your custom soundscapes to play again. AI can also create personalized audio based on your current state, with soundscapes and guidance for winding down or settling back into rest.\n\nMAKE YOUR EARBUDS YOUR OWN\nConnect SomniPods 3 or DUVA ONE to check battery levels, manage playback, set alarms, and adjust listening modes and noise relief. Keep your audio and device settings together, ready for the way you prefer to sleep.\n\nFitnexa is now DUVA.\nSleep tracking and device controls require compatible hardware. Available metrics and features vary by device. Heart rate, HRV, and bedroom environment monitoring require DUVA ONE.","facts":{"developer_id":1768495654,"developer_url":"https://duva.com","first_released":"2024-10-25T07:00:00Z","support_url":"https://duva.com/support","privacy_url":"https://blobtest202405202004.blob.core.windows.net/policy/Privacy_Policy.html","website_url":"https://duva.com/","app_version":"3.1.8","release_notes":"We have conducted some bug fixes to enhance the user experience","rating_current_version":4.77841,"rating_count_current_version":1945,"star_counts":[30,32,47,120,1715],"genres":["Health & Fitness","Food & Drink"],"languages":["EN"],"content_advisories":["Infrequent/Mild Medical/Treatment Information"],"device_families":["iphone","ipod"],"made_for_iphone_duo":false,"chart":null},"freshness":{"apple_read_at":"2026-11-11T05:01:12.723Z","catalog_read_at":"2026-10-26T02:25:13.412Z","reviews_checked_at":"2026-11-14T16:00:12.700Z","summary_written_at":"2026-11-05T03:27:12.719Z","placed_at":"2026-10-21T02:33:12.966Z","scored_at":"2026-11-14T17:10:12.686Z"},"editorial":{"one_liner":"Sleep tracking, pattern discovery, AI support and sound playback for sleep, with optional DUVA ONE hardware for body.","what_is":"DUVA is a Health & Fitness app that tracks sleep duration, stages, awakenings, movement, and sleeping positions.
