The most basic Vyew is free. It has all the same functionality as the paid packages. There are some usage limits, such as less people in a room at a time, and the free version includes advertising in the interface.
The free version is NOT a time-based trial. It is always free forever. There is zero risk to start using Vyew now.
Those who pay for Vyew get advertising removed, increased usage limits, and options to add-on other features for customizing and branding the interface. Prices starting as low as $6.95/mo.
When you buy a Vyew package, there is never any contracts associated with your account. You can quit, cancel or downgrade whenever you like.
