App Inventor tinyWebDB experiment: online Buzzer - Making my daughter's cellphone vibrates

Hi, today I have a little experiment .
There is an app called Xender that helps you transfer or share files fast from different devices. One function I like to use with my children it is to send a "buzz" , when you do this your friends cellphone vibrates, of course you can use this online if you are connected and in the same wifi.
So I was thinking how to do something similar , send a buzz or vibration, using App inventor.
SO I decided to use tinyWebDB. When you think in App sometimes it is to think about problems and how to solve them,

so these were my problems.

1.- How can I send a signal if tinyWebDB admits only text values
2.- Let's suppose I can send the signal, how could I reach a specific person?
3.- How can I stop it if someone sent me a buzz ?
4.- why Batman is so cool? er.. jejeje

well, I use tinyWebDB , and I recommend you create your custom TinyWebDB Service. Check this link about how to do it:

The app I did in the video took me like 1 hour, so it is not finished, but the main idea is in it. It is time for you to experiment and think about how to use it in your apps! Happy Inventing!
