I don't think is it possible --> Countup even when the phone is turned off
But I know that I can get the exactly date and time with the action : Get System Date Time
you guys can imagine a formula to use this info and add an integer each passes 10 minutes.
Eg:
01. Actual time 10:00 and pass 10 minute, are 10:10 = add +1 int
02. Other case,
Shutdown the system or app.
When you startap again:
The actual time pass more 120 minutes, and now are 12:10.
What formula I can use to add my integers?
10 minutes pass 11 times.
I need add 11 Int
Clear?
Thank you for your time!
