At the moment, we don't have a family subscription, we are working on it. The subscription is per person and profile. You can however enter the simulator as a Free member and play Live sessions in 2D (profile view). The rest of features are limited.
New users can enjoy a Trial for 30 days for free after registering. Afterwards, there are two options:
Annual subscription for 96€ (that's just 8€ every month).
Monthly subscription for 9,99 €.
