Hello everyone…  
I’m developing apps using thunkable classic for more than a year. Now, I’m interested building cross platform application.

My plan is to create an app that keeps track the SCREEN OFF time each day. Is there any possible extension for that ? If not, can anyone please suggest me how can I calculate that time ?

Thanks in advance.
