Personal records and arithmetic
Vialday records values you enter and performs arithmetic. It does not diagnose, prescribe, recommend substances or doses, or supply substances. Consult a qualified healthcare professional for medical decisions. Independently verify inputs, potency, units and results. Reminders depend on device settings and are not a guaranteed medical alert service.
Optional Pro purchases
The calculator and one active protocol are available without a Pro purchase. Monthly and annual Pro subscriptions renew automatically unless canceled at least 24 hours before the current period ends. The lifetime option is a one-time purchase. Price, billing period and any eligible trial appear before confirmation. Manage or cancel subscriptions in your App Store account settings. Refund requests are handled by Apple. Use Restore Purchases with the Apple Account used for purchase.
