Stress is invisible. But it can be measured.
Vela analyzes your heart rate variability (HRV) from your Apple Watch and turns it into a number that makes sense for you — not for a statistical average.
Everyone's HRV is different. That's why Vela builds your personal baseline during the first few days and uses it as a permanent reference. Your stress score is yours, calculated against your own history.
The essentials, without the noise
- Personalized 0–100 stress score
- Passive background measurement
- Daily, weekly and monthly history
- On-device processing — no external servers
Your data, yours alone.
Sync happens through your own iCloud. Vela has no servers. No mandatory subscription.
Requires Apple Watch with watchOS 26 or later.
