This design showcases a subscription modal for upgrading to a premium service tier, labeled 'Plus'. It displays two billing options, monthly and annually, with the annual option highlighted as a cost-saving choice. A separate 'Add ons' section is available, offering additional services for an extra fee. The total cost per month is clearly stated at the bottom, alongside a prominent 'Upgrade to Plus' call-to-action button. Users are reminded of the terms and conditions agreement before continuing with the upgrade process.
