How much does the Move app cost?

Could you please provide me with some information regarding the pricing structure of the Move app? Specifically, I'm wondering if there's a one-time fee to download the app, or if there are any recurring charges associated with its use. Additionally, are there any hidden costs or additional fees that users should be aware of? Understanding the cost of the Move app would be invaluable in helping me make an informed decision about whether or not to download and use it.
