Hi there, is there any way to create an app with a timer that will start on one device and the 2nd device connected via database will be able to see the timer started/fired on the 1st device?

Yes. Use the `seconds since 1970` block and set a cloud variable or cloud data source (e.g. Google Sheets cell) to its value when you want to start the timer. Then, check how long it’s been by subtracting `seconds since 1970` minus that value.

Hello @t.jul welcome to the community  
You can build this on a StP project using Firebase.

Here are the blocks you can use to save the value on Firebase when the timer starts:

These are the blocks to get the latest value:
