BUILT ON APPLE HEALTH
Base Level reads the data already in HealthKit. No required purchases, no manual data entry. If Apple Health has it, Base Level visualises it.
FREE & PLUS
Base Level is free with the last 30 days of your history. Upgrade to Plus for unlimited history and every advanced analytic, all computed on your device, no cloud required. Plus is a monthly or yearly subscription with a free trial.
PRIVACY FIRST
Your health data stays on your device. Without an account, nothing is ever uploaded. If you create an optional account, cloud-enabled features sync only what they need, encrypted in transit and at rest, and you can delete it anytime from Settings. Your data is never sold or shared with third parties.
Base Level Plus is an auto-renewable subscription. Payment is charged to your Apple ID at confirmation of purchase. The subscription renews automatically unless cancelled at least 24 hours before the end of the current period; manage or cancel anytime in your App Store account settings.
