Ara is a mono-profile toothbrush (only one user, therefore only one profile can be registered for each toothbrush).
Ara stocks the complete brushing sessions made offline including the areas brushed and syncs them with the app when reconnected: so you don’t need necessary to brush with the app to record your brushing session.
Therefore Ara is a mono-profile toothbrush because when you brush offline, the brush cannot differentiate the user.
So 1 Ara = 1 user = 1 dedicated profile.
So if you want to add a second profile to your account : you need to buy another toothbrush that will be dedicated to another user.
If you have a toothbrush V1, you can use multiple profiles with one toothbrush V1, please follow the link below:
