To wake up in the morning I use a special alarm clock for deaf people. This has an adjustable buzzer where you can adjust the frequency and volume with rotary knobs. This alarm clock also has outputs so that you can control a flash module and/or a vibrating cushion with a 2.5 mm jack plug.
The vibrating cushion has its own power supply (3x AA battery) and a 2 meter long thin but strong connection cable with 2.5 mm jack plug. The vibration box is 85x85x30 mm and made of black plactic. I place the vibrating cushion under my pillow and under the fitted sheet so that it does not slide away. This works fine. Nowadays the alarm clocks are more modern.
So it would be super useful to have a wireless Bluetooth vibrating cushion that can be activated via an alarm app on the iPhone:
Bellman Vibio is a wireless vibrating cushion that connects to your mobile phone via Bluetooth 5. It comes with a free app that allows you to create multiple alarms, choose vibration power, and allow notifications of calls or text messages. The vibrating disk can work completely independently. You store the wake-up times in the disk itself, as it were.
