The Shock Clock 3 is a wearable alarm built for people whose problem is snoozing rather than hearing. Pavlok says it starts with a vibration, sound or light, and if that fails, a mild electric zap follows. A snooze lock can make you complete a task, such as jumping jacks, scanning a barcode or solving a math problem, before the alarm stops. Everything is set in the Pavlok app over Bluetooth, which also shows sleep analysis. The box contains the module, a strap, a strap lock and a USB-C charging cable. For a deaf user, the wrist vibration is the useful part, and it wakes only the wearer. But the device depends on a phone and regular charging, and the zap is a strong deterrent that not everyone will want. Pavlok offers a 180-day money back guarantee. The store showed a non-USD price from our location, so pricing is pending.
