First things first, make sure your Adalo app has user authentication turned on. This could be through email and password, Google sign-in, or any other method Adalo supports.

Next, in the User collection, add a property to keep track of the last time the user was active:

• Property Name: lastActivity
• Property Type: Date & Time

For every screen or action that shows user activity:

• Add an action to update the lastActivity property of the logged-in user to the current date and time.

Example Action:

• Action: Update Logged-In User
• Property: lastActivity
• Value: Current Time

On every screen that needs authentication:

• Add a conditional action to check the difference between the current time and the lastActivity timestamp.
• If the difference is more than the session timeout period (like 30 minutes), send the user to the login screen.

Example Condition:

• Condition: Current Time > Logged-In User's lastActivity + 30 minutes
• Action If True: Link to Login Screen
• Action If False: No action (user stays on the current screen)

Now, test everything to make sure the session timeout logic works as it should:

• Log in as a user and pretend to be inactive for longer than the session timeout period.
• Make sure the user gets redirected to the login screen when the session times out.
• Test different scenarios to make sure everything is solid, like moving between screens or half-completing actions.

By following these steps, you can manage user sessions effectively, ensuring a secure and reliable user experience in your Adalo apps.
