I’m looking to build a healthcare app whose core value is a subscription-based model rather than pay-per-visit. Users will be able to choose between two membership levels, start with a free trial period, and move seamlessly into recurring billing. Here’s what I need: • Detailed technical plan that outlines architecture, data flow, and the subscription logic. • Functional prototype of the mobile app with screens for sign-up, plan selection, trial activation, upgrade/downgrade, and cancellation. • Robust billing engine that supports recurring charges, proration, and automatic renewals for both membership levels. • Admin dashboard to view active trials, churn statistics, and payment history. • Clean, secure code that meets industry standards for handling health-related information. - API integration to Whoop & Apple healthcare I’m happy to collaborate on tech stack choice as long as it supports scalable subscription management and integrates easily with common payment gateways. If you’ve implemented free trials, tiered memberships, or healthcare compliance before, I’d love to see your work.
