Freemium

Freemium is a way of selling products or services. A freemium product or service is usually a basic version that anyone can use for free, but if people want access to more features or a better version of the product, they have to pay for it. People can decide to pay for the more advanced version of the product or service, but if they don't want to, they can still use the basic version for free.
