"Simple Bell" is just like how it sounds.
You can choose from two different sounds.
Tap it once, and it will "ding" once.
If you hold the button longer though, it will "rrring" a bit longer.
Since you can choose which sound you want, there are no timer functions, thus keeping it very simple.
支援平台：iPhone, iPad
