Pavlok Shock Clock 2 Review

The Pavlok Shock Clock 2 is a wearable wrist alarm for individuals who sleep through standard audio alerts. It uses physical stimuli to condition your brain to associate the alarm time with a physical sensation. This conditioning helps you wake up to avoid the final zap, providing a reliable alternative to hitting the snooze button.

The system uses a customizable sequence of vibrations, audible beeps, and electric zaps. You can set an escalating sequence—starting with a vibration, followed by a beep, and ending with a zap—to ensure you do not sleep through your designated wake-up time. Users can adjust the zap intensity to wake up safely.

The hardware pairs with a dedicated mobile application compatible with Android and iOS smartphones. The Pavlok app controls alarm settings, regulates stimulus intensity, and tracks sleep patterns. The manufacturer includes a one-year replacement warranty for hardware issues.
