Vela HRV vs Dusk Journal

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.

Dusk is a private journal powered by Apple Intelligence. Write freely each evening — Dusk reads what you wrote and asks you one thoughtful question back. No advice. No judgement. Just the right question at the right moment. On the free plan, everything runs on your iPhone. Your words never leave your device. HOW IT WORKS Write tonight's entry in your own words. After a few sentences, Dusk quietly generates a reflection question — powered by Apple Intelligence, entirely on-device. Respond if you want, or just keep writing. Either way, your entry is saved privately and permanently. Over time, Dusk spots patterns in your writing — what days you feel best, what triggers stress, what you keep coming back to. The kind of insight that only emerges when someone has been paying close attention. PRIVATE BY DESIGN Free plan: every reflection question is generated by Apple Intelligence on your device. No servers. No account. Nothing sent anywhere. Pro deep insights: your last 30 entries are sent securely, analysed, then immediately deleted. Never stored. Never used for training.
