How much is Dash app?

Could you please elaborate on the pricing structure of the Dash app? I'm interested in understanding whether there are any upfront costs, subscription fees, or transaction charges associated with its usage. Additionally, is there a free version available for users to try before committing to a paid option? Clarifying these aspects would help me make an informed decision regarding the financial implications of adopting the Dash app for my needs. Thank you for your assistance in this matter.
