Oct 10, 2026
New version 1.0.3 → 1.1.1

New in 1.1.1: • Three sound journeys – VYRE, NOCTYS and VOYA: five quiet minutes that feel like a small journey. Plus a full-screen dust cloud that slowly turns. • Sound now has its own tab – with the Daily Thought and the right journey for the time of day. • “Your week”: your weekly review with your calmest day and what helped you. • A card shows you the next sensible step – right for your moment. • Time-of-day mood: cool in the morning, warm in the evening. • Breathing on Apple Watch: gentle, continuous taps and clearly noticeable changes between breathing in and out. • iPhone Duo: A dust cloud opens up as you unfold the phone. When it's half-folded, the cloud floats at the top while you use the controls at the bottom. • Siri and Shortcuts, a widget with the Daily Thought and many small improvements.

About

Your body notices first. NEVYN makes it visible. A score from 0 to 100 shows you live how much load your body is under right now – on Apple Watch and iPhone. Measured against you, not an average person. Requires an Apple Watch. ■ See what’s going on right now One glance at your wrist: calm, balanced, elevated or high. NEVYN reads HRV and heart rate from Apple Health and compares them with your own values at the same time of day. NEVYN recognizes workouts, movement and sleep – they don’t count as load. ■ Notice right away when it gets too much If your load stays high for a while, your Watch lets you know – quietly, no alarm. A short breathing exercise with gentle haptics helps you come down in 1 to 5 minutes. ■ Spot when stress keeps catching you After about three weeks, NEVYN shows your patterns: Thursday afternoon, the commute, the second coffee. If you like, NEVYN gives you a heads-up shortly before – so you’re prepared. ■ Mix your own calm NEVYN Sound: soundscapes you mix with one finger – Focus, Depth, Current and Waves. With timer, widget and Control Center. ■ Your day at a glance Sleep, training, resting heart rate and your relaxed minutes – in the app, in widgets and as a complication right on your watch face. ■ Made for iPhone Duo Unfolded, three pages: Now, Sound, and History & patterns. Half-folded, your score on top and your soundscape below. Private by design Your health data stays on your iPhone and Apple Watch. We never see it. • No account – No sign-up, no login. • No cloud – Processing only on your devices. • No tracking – No ads, no analytics. • Deletable – Remove all data with one tap. NEVYN Pro: try free for 7 days, then a monthly or yearly subscription. Without a subscription, the sound “Depth” and the breathing exercise on Apple Watch stay free. The subscription renews automatically unless cancelled at least 24 hours before the end of the period – anytime in your Apple ID settings.
