subscriptions. Full functionality out of the box.

By the numbers
Built Different
Four numbers that explain why Pulsyn isn't just another smart ring.
Local first
On-device by default. Cloud by choice.
Your health data lives on your phone, not our servers. If you opt into cloud backup, it's end-to-end encrypted with keys only you hold. We designed it so you never have to trust us.
Seven days per charge
One week. No anxiety.
Wear it Monday. Charge it Sunday. The charging case extends that to 60 days total — one charge a month if you want it.
Meet Milo
Your AI health agent. Always on, always private.
Milo runs entirely on your phone — no internet required, no subscription, no data leaving your device. It learns your patterns and surfaces insights before you think to ask.
Ultralight
So light you forget it's there.
At just 2.4–4g depending on size, Rune 1 is so light you'll forget you're wearing it. Hardware that disappears.
