Create a Free Trial for a Blocks App

When you set up your app's pricing in the app dashboard, you can choose to provide users with a free trial. This is recommended especially if you don't provide a free version of your app, so you can let users experience your app's value before they decide whether to upgrade.

Once you choose to add a free trial, your app market listing will show how many days of free trial the app offers. 

When users are in the free trial period, their app works as if it's upgraded. When the free trial is over, Wix will automatically move them to the plan they selected. As the app developer, you'll see the plan they selected in the vendorProductId field of the Velo decodedAppInstance object, from the momenet they began the free trial.
