Read full descriptionHide full description
NotMyPii verifies your age using your ECG waveform from Apple Watch — not a government ID, not a face scan, not a username. Open the link from a partner site on your iPhone, place your finger on the Apple Watch Digital Crown for 30 seconds, and receive a signed verification result. Your ECG is processed in memory and never stored. No account is created. No personal information is collected. Requires iPhone and Apple Watch Series 4 or later.

Verdict
The clearest difference is update cadence: NotMyPii at every 2 days against BGC Science's every 2 months. BGC Science's advantage is iOS requirement (12.0 vs 16.0). On price, ads, in-app purchases and device support there is nothing between them.
