Is the Cetus app free?

Could you please clarify the pricing policy of the Cetus app? I've heard a lot about its features and functionality in the cryptocurrency community, but I'm unsure if it's available free of charge. Would you say it's a free app with optional in-app purchases or is there a one-time or recurring subscription fee involved? Clarifying this upfront would help me and others in the community make an informed decision about whether to download and use the app. Thank you for your time and assistance in this matter.
