Hi, So I am actually building an app that can measure how long you have been on screen. Is there any way to measure how long you have been on screen?

Hi @p7s welcome to the community.

You can do this with a [variable](https://docs.thunkable.com/variables) and the [device time](https://docs.thunkable.com/device#get-current-time-and-date) block.

Use the variable to store when the app opens and then the device time to check the time that has elapsed since it was opened.

Hope that helps.
