Helix Vault is a private health tracker built for people who actually need one chronic illness, migraine, or mental health condition and anyone managing a complex set of symptoms or medications.
Everything stays on your device. Your data syncs through your personal iCloud, never through our servers. We can't read it because we never see it.
A HOME SCREEN BUILT FOR YOU
