Will you ever add a required subscription?

No. The no-subscription model is a core product decision, not a pricing strategy. We make money when you buy the ring.

What if my size doesn't fit?

A Pulsyn sizing kit is forthcoming and will let you confirm your fit at home. You can exchange for the correct size within 30 days.

Is my health data backed up?

Optionally. If you enable cloud backup, it is end-to-end encrypted with keys only you hold. We cannot access it.

1-year standard warranty. Extended Protection (+$30) covers 2 years including accidental damage.

What makes the Rune 1 different from other smart rings?

Most smart rings send your health data to the cloud by default. The Rune 1 keeps it on your phone. Pulsyn cannot access your data because we never receive it. Your health insights run through Pulsyn's own fine-tunes of Qwen 3.5, directly on your device, so you get analysis without an internet connection. There is no required subscription. All core tracking and AI features are free. The ring costs $200.

Do I need a subscription to use the Pulsyn Rune 1?

No. Every Rune 1 includes all core health tracking and on-device AI insights at no extra charge. You do not need to pay monthly to see your heart rate, sleep stages, or local AI analysis. Pulsyn Pro is $6 per month if you want it. It adds cloud sync with end-to-end encryption, deeper analytics, and extended data history. You control the keys. We cannot read your backups.

How does on-device AI work on the Rune 1?

The AI runs on your phone, not on distant servers. The Rune 1 uses Pulsyn's own fine-tunes of Qwen 3.5, lightweight AI models that run locally on your phone. Your heart rate, sleep, and activity data stay on the device for processing. You do not need an internet connection to receive insights. Nothing leaves your phone unless you explicitly choose to enable cloud backup.

Personal, by design.

The more you wear it, the more it learns you.

Rune 1 learns your patterns over time. Your data stays private. As its models get to know your routines, they shape recommendations around you, with results up to 3× more personalized than Oura.

Personal Science Lab Pulsyn Pro

Your ring, running
experiments on you.

Describe what you want to test. Pulsyn designs the experiment: baseline, intervention, measurement. Your ring collects the data silently. You just log compliance. The app shows you what's actually moving the needle.

1

Describe

Tell the app what you want to test. A supplement, a sleep habit, a morning routine. The AI designs the protocol: baseline window, intervention schedule, and the biometrics that matter.
2

Measure

Your ring runs the experiment automatically. Baseline first, then intervention, collecting HRV, sleep stages, skin temperature, and activity. No manual logging required.
3

Discover

See your directional trend against your own baseline. No spreadsheets, no guesswork, no causal claims. Just clean, personal evidence of what's actually moving the needle.

No other wearable gives you a structured, AI-designed personal experiment with automatic biometric measurement.

A day with Rune 1

You forget you're wearing it. You feel the day, not the ring.

Morning

07:14

You wake. Before the kettle boils, the ring already knows how the night went and what today can take.

Readiness: 82
Body battery: 96
HRV: 52ms

Looks like a strong recovery overnight.

Day

14:32

A meeting runs hot. Your stress climbs before you notice it, so North flags it and shows what is left in the tank.

Body battery: 58
HRV: 38ms
Steps: 4280

Suggests a short pause might help.

Evening

21:48

The tank is running low. The ring suggests winding down now so tomorrow starts where today did.

Body battery: 23
HRV: 38ms
Steps today: 7840

Consider starting your wind-down.

Night

03:20

You sleep. The ring maps every stage so the morning score is built on what your body actually did.

Deep: 1.7h
REM: 1.9h
Light: 4.2h

Looks like steady sleep.
