About NEVYN: Stress Monitor & HRV
Your body notices first. NEVYN makes it visible. The packed calendar, the difficult conversation, the commute: NEVYN analyzes the data from your Apple Watch. If your load stays elevated for a while, you get a quiet heads-up – and a short breathing exercise helps you find your calm again. Requires an Apple Watch. ■ Notice right away when it gets too much If your load stays high for a while, your Watch lets you know – a soft tap on your wrist, not an alarm. A short breathing exercise with gentle haptics brings you back to yourself in 1 to 5 minutes. ■ Spot the moments that keep getting to you Thursday afternoon. The drive to work. The second coffee. After about three weeks, NEVYN shows you your patterns – and, if you like, reminds you shortly before, so you’re prepared. ■ Training isn’t stress NEVYN recognizes workouts, movement and sleep from your Apple Health data. A raised heart rate during those times doesn’t count as load and isn’t included in your score. ■ Mix your own calm NEVYN Sound: soundscapes you mix with one finger – Focus, Depth, Current and Waves. For unwinding, concentrating or drifting off to sleep. With timer, widget and Control Center. ■ One glance is all it takes Calm, balanced, elevated or high: a score from 0 to 100 shows how much load your body is under right now – on your watch face, in widgets and in the app. Plus sleep, training, resting heart rate and your relaxed minutes. ■ Measured against you, not the average NEVYN reads HRV and heart rate from Apple Health and compares them with your own values at the same time of day. So you see what’s normal for you – not for someone else. ■ 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.

What’s new
Version 1.5 · Updated October 23, 2026
• Four new sound journeys: AERA for breathing, SOMNYS for falling asleep, AURYA for the morning, ORYN for focus – each with its own shape of the sound cloud. • Tap a card: sleep, HRV, heart rate, resting heart rate and training show you the last 7 days. • Relaxed now also counts mindful minutes from other apps. • Patterns now live in your history, and “Your day” can be collapsed. • Breathing on Apple Watch: calmer haptics – even taps while breathing in, one cue to breathe out.
