The carer taps once on their own phone on arrival. The app records the time and fixes the location, checks it against a radius around the client's address, and puts the visit on the office map. A second tap on departure. No signal in the house? The record is stored with its original time and uploads later. Nothing is attached to the client's home, nothing is dialled, and the carer keeps their dignity.
Because the same tap starts the care record, the notes and the medication entries are tied to a verified visit rather than floating separately.
