Hey folks,

Would you know if Glide Tables database actively update the “Now” value in a Math column while the app is inactive? e.g. like Airtable - think they update these dynamic columns once an hour while nobody is using the table.

Cheers,

E

Computed columns, such as the math column do not store values. They calculate values directly on the end user’s device as needed. The NOW value is determined by the user’s local time on their device. While the app is open and active, it will be actively updating the NOW value at least every 10 seconds.
