Procreate is a premium app that requires purchase. There isn't an official way to use free Procreate as it is designed to provide professional grade features and a user-friendly interface, all of which justify the purchase cost. Despite this, artists can explore free alternatives that provide similar functionality to Procreate, such as Autodesk Sketchbook or Krita, which might suit their needs without the associated costs. It's important to note, free alternatives may not have all the advanced features that Procreate offers.
