I need a complete customer-loyalty solution for my café that spans iOS, Android and a browser-based admin panel. The mobile apps must authenticate primarily by one-time password sent to the guest’s phone, with optional face or fingerprint sign-in for returning users. Each account will be keyed to the customer’s mobile number so it can sync seamlessly with the Foodics Cashier Console; you’ll handle that API integration so staff instantly recognise a guest the moment the number appears at checkout. Inside the app guests will earn points, redeem them for rewards. View ongoing promotions. Push notifications to app once the promotion is posting in admin panel. A lightweight referral feature should let current members invite friends and watch both accounts grow faster. The web admin panel has two roles: marketing (setting up campaigns, rewards, push messages) and operations (real-time customer lookup, manual point adjustments, analytics export). I’m happy to discuss what off-the-shelf UI kits or charting libraries you prefer as long as they remain responsive and secure. To move forward I’d like to see concept work or completed loyalty apps you’ve already delivered—wireframes, design systems, or short demo reels are all fine. Once we agree on the build we can set up a separate, negotiable annual support package covering security patches, OS upgrades and minor feature tweaks. Please share: 1. Your high-level architecture proposal (native, Flutter, React Native, etc.) 2. A timeline that breaks down milestones from design hand-off to App Store / Play Store submission and admin panel deployment. Kindly make sure that NO monthly recurring payments are involved. Try your best to keep everything one time payment or Free. I’m open to any additional ideas you have that could make the user journey smoother or the reward mechanics more engaging.
