(Red Fox) I’ve reviewed your requirements for the FlutterFlow-based mobile app and can deliver a clean, production-ready build for both iOS and Android exactly as per your specifications. I specialize in FlutterFlow development with strong experience in Firebase integration and subscription-based app architecture, including RevenueCat and OneSignal setups. My approach: • Build all 11 screens in FlutterFlow strictly following your PRD and design system • Set up Firebase Auth (email, Apple, Google sign-in) with secure user management • Design Firestore structure for profiles, check-ins, streaks, and progress tracking • Integrate RevenueCat for monthly and yearly subscription flows • Configure OneSignal for push notifications and scheduling logic • Ensure smooth state handling and clean reusable components in FlutterFlow • Prepare full project handover with clear structure and documentation Workflow: • Work in structured milestones (5-hour increments as requested) • Provide daily updates and short walkthrough videos per milestone • Ensure each build phase is reviewed before moving forward I focus on building scalable, maintainable FlutterFlow apps that are ready for production and store submission without rework. I’m available to start immediately and can follow your PRD precisely while also flagging any UX improvements if needed during development.

@visionvivante

Red Fox I read your requirements carefully, and I understand this is an execution-focused FlutterFlow build where the product direction, UI system, and flows are already finalized. That workflow works well for me because it keeps development fast, structured, and milestone-driven. I have experience with: • FlutterFlow production builds • Firebase Auth + Firestore architecture • RevenueCat subscription integration • OneSignal push notifications • App Store / Google Play deployment • GitHub-based project handoff and version control I’m comfortable building: • Email, Apple, and Google authentication • User profiles, streak tracking, and progress systems • Real-time Firestore structures • Subscription flows (monthly/annual) • Push scheduling and onboarding logic • Clean responsive mobile UI matching design specs exactly I also appreciate your milestone/checkpoint workflow with async updates and walkthroughs — that’s usually the best way to keep builds efficient and transparent. I understand the importance of: • Pixel-accurate implementation • Stable Firebase architecture • Clean FlutterFlow organization • Smooth app-store-ready performance I can also provide app examples and walkthroughs during a quick call/chat and discuss how I usually structure FlutterFlow + Firebase projects for scalability and clean maintenance. I’m available to start immediately and comfortable with long-term collaboration if the first phase goes well.

@redsparkinfo

Red Fox I went through your requirements carefully, and I appreciate how clearly the scope, design system, and workflows are already defined. FlutterFlow is my primary build environment, and I’ve worked extensively with Firebase authentication, Firestore structures, real time updates, RevenueCat subscriptions, and push notification systems including OneSignal. Your approach to milestone based delivery and async communication also aligns well with how I prefer to work. Daily progress updates and short walkthroughs help maintain momentum and avoid surprises during development. I also like that you’re open to small UX observations during the build phase. While I fully respect product ownership staying on your side, I do pay close attention to interaction flow and edge cases while implementing features. I can assist with the complete Phase 1 build including authentication flows, subscription setup, Firestore architecture, notification scheduling, testing, and final App Store and Google Play submission support. I’m ready to begin immediately and can commit consistent attention to the project until completion. Looking forward to discussing the first milestone. Thanks Dhruv

Interesting project, I will build all 11 screens in FlutterFlow — Firebase Auth (email, Apple, Google), Firestore structure for check-ins, streaks, and progress, RevenueCat subscription flow, and OneSignal push scheduling — with a clean, commented project handoff. For streak tracking, I will store daily check-in timestamps in a subcollection rather than a single document field — this avoids hitting Firestore document size limits as user history grows and makes querying date ranges far more efficient. Questions: 1) Are the monthly/annual plans the only RevenueCat offerings, or do you plan a lifetime tier later? 2) Do you have a OneSignal account set up, or should I configure that from scratch? Looking forward to potentially working together. Thanks, Kamran

Hi there, I see you’re looking for a FlutterFlow developer to create a mobile app with 11 screens using Firebase and RevenueCat. With around 10 years of experience in mobile app development, I’ve worked extensively with Flutter and Firebase, building engaging apps that users love. Your goal of integrating RevenueCat for subscriptions is a smart move, and I can help set that up efficiently. I also have experience with GitHub for version control, so collaboration will be smooth. I understand the importance of communication and reliability in our partnership, and I prioritize those values in my work. Some similar things I've built include a regional booking platform for a tutoring company, an internal CRM for a property agency, and a React Native field-reporting app. Let’s connect and make this project a success. Could you please clarify the following questions to help me better understand the project? Q1: What specific functionalities do you want for each of the 11 screens? Q2: Are there any design guidelines or branding elements you want to follow? Q3: What is your preferred timeline for the project's completion?

Having read your project description thoroughly, I am confident that my rich experience as an AI and Embedded Systems Engineer will be invaluable in delivering the results you need. Not only do I possess an expert understanding of FlutterFlow, but I also bring to the table strong familiarity with Firebase, including Auth, Firestore, real-time data, and Cloud Functions, elements central to your app's functionality. Furthermore, my proficiency in integrating RevenueCat for in-app subscriptions along with OneSignal for push notifications adds a winning edge to my candidacy. Throughout my career, I've learned to bring sharp attention to detail while executing projects precisely as directed—an attribute vital to your app development where final design decisions rest with you. Nonetheless, should I notice any minute UX issues or have any small refinement suggestions during the build - rest assured, I'll communicate this carefully and prioritize your vision.

@AnhTVc

Red Fox Your process and expectations make sense, and honestly this is the kind of structured build workflow I work best in. I’m an independent developer, available to start immediately, and comfortable working in milestone-based delivery with daily async updates and review checkpoints. I have solid experience with FlutterFlow, Firebase, RevenueCat, and OneSignal, including authentication flows, Firestore data modeling, subscription handling, streak/progress systems, and push notification workflows. Since your product/design decisions are already finalized, I can stay focused on execution quality, performance, and keeping the build clean and scalable. What stands out to me is that you already have the PRD, design system, interaction states, and user flows prepared. That usually leads to a much smoother and faster production cycle with fewer revisions and clearer milestone reviews. I also appreciate that you welcome UX observations during development. I’m careful about respecting product direction while still flagging small usability or flow improvements when they genuinely help the experience. I can deliver: • Pixel-accurate FlutterFlow implementation • Firebase Auth + Firestore architecture • RevenueCat subscriptions • OneSignal integration • Store submission assistance • Clean project handoff with GitHub repo and documentation Happy to discuss timeline, milestone structure, and review the Phase 1 scope in detail. Kind regards.
