Yes, of course you can use the iHealth Lina HS2 scale with multiple users.
For this, each user must have his own iHealth account. The iHealth app is multi-user so you can track multiple people from the same smartphone.
The iHealth Lina scale allows you to make Online measurements or Offline measurement.
An Online measurement is done with the iHealth MyVitals app open on his account and the scale connected to the smartphone. The result of the measurement is then directly saved in the user's account.
Note - When used by multiple users, ensure that only one iHealth MyVitals app is open on smartphones within range of Bluetooth to avoid any conflict in the assignment of results.
An Offline measurement is done without the iHealth MyVitals application. The result of the measurement is then stored in the memory of the scale until the results are synchronized.
The synchronization is done automatically as soon as the scale is connected again to the iHealth MyVitals application (whatever the user is connected).
The data stored in the scale is uploaded to the iHealth secure cloud. Each user can then retrieve their data by going to MENU > Weight > Filter Data.
