Can Timerfly show who works from the office and who works remotely?

Yes, on Business. Add your office’s internet address, and work sent from it counts as office; anything else as remote. Nobody has to check in and no location is tracked.

1. 1Be in the office, on the office internet, with any VPN off.
2. 2Open Settings → Office networks.
3. 3Click add it next to “You’re on …”, or type the address and click Add.

You see Office or Remote next to each person on Team, on each day, and as office and remote days in Reports and the Excel.

It works best with a fixed (static) address from your internet provider.
