Many digital health apps allow users to search for any patient in a massive, centralized directory. We think that approach is outdated and insecure. At VITIA, we use an “Invitation-Only” model. No one, not even your health provider, can search for you, and they cannot see your wearable data or health diaries unless you explicitly send them an invitation token from your app. You decide exactly what to share, and you can hit the “Kill Switch” to revoke that access at any exact moment. Security means you hold the keys to your own digital vault.
