NEVYN
Your Apple Watch as a stress monitor, scored 0–100
Your Apple Watch measures heart rate and HRV all day, but the numbers rarely tell you anything. NEVYN turns them into one clear load score from 0 to 100, compared with your own baseline at the same time of day, and says what helps right now. No account, no cloud, no tracking: everything is calculated on your iPhone and Apple Watch. Free for 3 days, no subscription needed; then monthly or yearly with Family Sharing. Requires an Apple Watch. Wellness app, not a medical diagnosis.
Features
- Load score 0–100 against your own baseline at the same time of day
- Notification with a vibration when your load stays high
- Breathing on your watch, 1–5 minutes, with a before/after result
- Patterns from day 1 using your Apple Health history
- Workouts and movement don't count as stress
- Complications and widgets, including Horizon on your watch face
- Morning and evening summary in one sentence
Use Cases
- See during a busy workday whether your body is actually under load
- Get a nudge and a short breathing session when stress stays high
- Find out at which times and weekdays you're usually elevated
- Check in the morning how well you recovered overnight

Hi Fazier, I'm Gianfranco, solo founder from Wiesbaden, Germany. I built NEVYN because my Apple Watch collected heart rate and HRV all day and I still had no idea whether I was actually stressed. Most apps compare you with a population average. NEVYN compares you with yourself, at the same time of day, because a heart rate of 80 at 9 am means something different than at 10 pm. Two things I cared about: it has to work on day 1 (it reads your Apple Health history instead of making you wait a week), and your health data never leaves your devices. No account, no server, no analytics. It's free for 3 days, no subscription needed. I'd love honest feedback, especially from people who've tried other HRV apps: where does the score feel right, where does it feel off?
