Timer control in mobile app

How can I create a timer (display) in a Retool mobile app, since the control is not (yet?) available for mobile?
I would like to display the hh:mm:ss since a screen has been opened.

Hey @Gianluca! We do have a feature request for the timer component in mobile apps, so we will update you here when we have any additional information on that for you. In the interim, I did write up a couple of JS queries to calculate this for you. It's probably not perfect, but seemed to work pretty well.

Get the current time when the app is opened:

Ensuring that this query runs on app start:

Calculate the difference (as often as you want):

Here I'm running it every second (after a 1 second delay). You can alter these times based on the absolute precision that you want to show.

Then display that information in a text component in the app:

Let me know if you have any questions!
