Apple’s built-in activity and fitness tracker for iPhone and Apple Watch, with health data processed on-device and synced to iCloud using end-to-end encryption that Apple cannot read.

Apple Health stands out among mainstream fitness trackers specifically because sensitive health data (activity, heart rate, sleep, reproductive health) is end-to-end encrypted in iCloud and processed on-device rather than on Apple’s servers. The catch is that it is iOS-only, closed-source, and entirely within Apple’s ecosystem, so you are trusting Apple’s published architecture rather than auditable code. The right pick for iPhone users who want fitness tracking without handing raw health data to an ad-supported platform.
Measures the security configuration of the tool's own website, not the privacy of the product itself. A strong tool can still score low here.
