Simple model from marketplace

how can i install the simple model, it says that is free but i can’t install it.

Most of the items in the Marketplace cannot be installed in the apps that are on the free plan. So yes, a product in the marketplace is free, but it is available only when the app is on the Scale plan.

Regards,
Mark

how do i get on the scale plan?

Click here:

Then here:

Then select Payment Profiles and add your credit card by clicking “Add a Payment Profile”

Once you have a credit card added, click the Manage icon and then select Billing Plan as shown below.

You will see available plans and a button to switch.

Hope this helps.
