I’m ready to turn my home-solar cleaning service into a smooth, mobile-first experience. The goal is an iOS and Android app where customers can quickly find our technicians, pick a time, pay, and receive confirmation—all in a clean, straightforward interface. Core flow • New and returning customers create an account or sign in (email, Apple, Google). • A Google-Maps powered address picker confirms the exact rooftop location. • The live calendar shows only the slots we truly have available; once chosen, that slot locks automatically. • Checkout happens inside the app through PayPal or Stripe, followed by an on-screen receipt plus email/SMS confirmation. Look & feel I lean toward a simple, minimalist UI—white space, clear typography, just enough color for calls-to-action. If you already have a favorite component library that supports this style, mention it. Tech notes – Native, React Native or Flutter are all fine as long as the final builds pass App Store and Play Store review. – Calendar can sync to a central Google Calendar or a custom backend—happy to discuss what’s fastest. – Notifications may run through Firebase or a comparable service; reliability is more important than brand. Deliverables 1. Source code with clear README and environment setup instructions. 2. Two store-ready builds (iOS & Android) plus guidance for first submission. 3. Admin-side endpoints or lightweight dashboard to add/modify time slots. 4. One round of post-launch bug fixes (within 30 days). If this matches your skill set and you’ve shipped booking or field-service apps before, tell me how you would structure the project and an estimated timeline.
