You can use a Pryme Vessyl at home and at work. These will both sync to the same phone.
Once you’ve finished setting up your account with your first Pryme Vessyl, swipe up to the Profile page in the app. Tap on the gear icons to go into the settings page. From here, just select "Add A New Vessyl" and follow the on-screen prompts to link another Vessyl with your account.
The app will continue to work the same. Any drinks you take from either Vessyl will be added to your timeline and factored into your Pryme.
