Frequently Asked Questions
I always sleep past my alarm clock. Will this wake me up?
I always sleep past my alarm clock. Will this wake me up?
Yes. Vibration – especially on the wrist – stimulates the brain more effectively than sound alone. This alarm is designed specifically for heavy sleepers who don't respond to traditional alarm clocks or wake-up lights. The strong vibration gradually intensifies until you wake up, even from a deep sleep. Over 500 heavy sleepers tested the product for 50 days, and 99% said they woke up on time. For many, this has been the solution to finally waking up reliably in the morning.
Isn't this the same as any smartwatch?
Isn't this the same as any smartwatch?
No. While smartwatches offer many features, Coreva is designed specifically for waking you up – not for tracking exercise or displaying notifications. Unlike most smartwatches, it actually produces a wake-up vibration that's optimized for deep sleepers. With over 14 days of battery life, it's made to be worn while you sleep and barely noticeable on your wrist. This way you wake up effectively without disturbing others – the solution for a peaceful but safe awakening.
