We charge for software, not for your data. Pro is less than the ring you already wear — and unlike the ring, it actually explains the data. Pick the tier that matches how deep you want to go.
For people curious whether any of this works on their data.
For people serious about understanding their body — not just measuring it.
For households, training groups, or a doctor following up to 25 patients.
The whole point of Longvai is to be honest about your body. We can't do that and quietly monetize you on the side.
Subscription revenue means our incentive is to keep you happy enough to renew next month. Data monetization would mean our incentive is to make you visible to advertisers. They're not the same business — and we picked the one we can stay proud of.
No credit card. No commitment. Your data stays yours either way.
