Horse Tip Subscription App

I run a horse-tipping service and I’m ready to turn it into a fully-fledged mobile experience. What I need first is a native-feeling app that works on both iPhone and Android. New and existing followers will create a password-protected account, choose between a monthly or yearly plan, and then unlock my weekly picks. Inside the app they should see the current week’s selections in a clean, easy-to-scan screen, while at the same time receiving the same picks automatically by email. I’d like the email side handled through a simple list manager (Firebase, Mailchimp, or similar) so I can also push out a short newsletter every week. Core workflow • Secure sign-up / log-in • In-app purchase or Stripe subscription flow with monthly or yearly option • Admin panel where I paste each week’s tips once and they publish to both the app and an email blast • Basic analytics so I can track active users and churn • Social buttons that open my Instagram and Facebook pages and encourage sharing • Store-ready builds for the App Store and Google Play A clear, annotated hand-off is important to me because I’m new to the app world; please factor in some screen-share walkthroughs or concise documentation so I can manage simple updates myself later on. If you’re comfortable with cross-platform stacks like Flutter or React Native, payment gateways, and email integrations, I’d love to hear how you’d tackle this and what timeline you envision.
