There is an actual bell and an app bell that rings when pressed. However, when you are in another room, you may not always hear it.
That's where "Bell for Remote" comes in.
With this app, your device will be notified when the bell is pressed on your device at the door.
Now you can go to the bathroom with peace of mind.

Turn your smartphone or tablet into a call bell. Use it at the counter of a store or hotel.
Even if you are not at the counter, if a customer presses it, you will be notified. Don't forget to protect your device from theft.

For the first device, you need to register your email and password.
For the second and subsequent devices, please login with the registered email. Notifications will be sent to all devices that are logged in with the same email.
The PIN is set to prevent the customer from manipulating it. The initial value is "0000", which can be changed from the Setting screen.
The default value is "0000". Even if there are many devices, you can see which device was pressed.
