Yes, Smart Elite+ HEM-7600T can be used by multiple users. The same blood pressure monitor can be synced with multiple mobile devices.
For both models, after a reading is taken, be sure to sync the reading with the desired mobile device. Once that is done, the same reading cannot be transferred to another mobile device. Hence you can repeat the same process with a different user and different mobile device.
