Capture in the real workplace
Papershift
App, browser and a shared tablet terminal where employees identify by PIN or signature, plus offline use with real-time sync to the cloud — desk and deskless are covered, and employees can view and edit their own records with approval shown. Geofencing via GPS restricts where times may be recorded, but I found no public information on what the GPS data stores or whether it can be switched off, and the change history is gated to the top plan.

The breadth is real — PC, mobile with true offline recording, and three hardware terminals with RFID or fingerprint — and employees can correct their own bookings. But GPS is marketed to 'die Leistungen verorten und nachweisen' with no stated limits and no word on what can be switched off, and supervisor approval of corrections is optional with no audit trail of who changed what — that is a §87 negotiation, not a done deal.
