Red Fox I've carefully reviewed the requirements and appreciate how well-defined the project is. Since the product, designs, PRD, and content are already finalized, this is exactly the kind of execution-focused build I enjoy working on. I have experience working with FlutterFlow, Firebase Authentication, Firestore, Cloud Functions, subscription-based applications, and third-party integrations. I'm comfortable implementing custom Dart code within FlutterFlow when needed and following detailed specifications closely. I can deliver: ✓ All 11 screens built to spec ✓ Firebase Auth (Email, Google, Apple) ✓ Firestore data structure and user flows ✓ RevenueCat subscription integration ✓ OneSignal push notifications ✓ Firebase Analytics integration ✓ App Store and Google Play submission support ✓ Clean project handoff and documentation I work independently, provide regular progress updates, and am comfortable with milestone-based delivery and review cycles. A quick question: do you already have the 11 screens grouped into milestone batches, or would you prefer the developer to propose the implementation sequence? I am available to start immediately. Best regards, Rajesh

Red Fox I've carefully read through your complete PRD notes and requirements for this men's mental performance app. I'm a FlutterFlow expert with strong Dart/Flutter custom code skills and hands-on experience with Firebase (Auth, Firestore, Cloud Functions), RevenueCat subscriptions, and OneSignal push notifications. I can handle all 11 screens as specified — from user auth (email, Apple, Google) to streak tracking with server-authoritative Cloud Functions respecting user timezones, Firestore data structure, RevenueCat monthly/annual subscription integration, and App Store + Google Play submission. I work independently, communicate daily via async check-ins, and deliver milestone-by-milestone with video walkthroughs. I'm available to start immediately. Could you share the PRD and design specs so we can align before Day 1? Regards, Harsh Thoriya

Red Fox Hi, I understand you need a FlutterFlow expert to build a men’s mental performance mobile app exactly based on your PRD, with Firebase, RevenueCat, and OneSignal fully integrated, and I promise you will be happy with the result. If not, you do not pay. I will also provide three months of free maintenance after launch. I can build the full app in FlutterFlow with all 11 Phase 1 screens, Firebase authentication (Apple, Google, email), Firestore setup for user data and streak tracking, and Cloud Functions for server-side logic like streak calculation and time-zone handling. The app will also include RevenueCat subscription setup and OneSignal push notifications exactly as defined in your PRD. I will use FlutterFlow with custom Dart actions where needed, Firebase (Auth, Firestore, Cloud Functions), RevenueCat for subscriptions, and OneSignal for notifications to ensure everything works smoothly on both iOS and Android with native-level performance. The project will include clean FlutterFlow project delivery, full source handoff via GitHub, App Store and Play Store submission support, and complete implementation as per your PRD without changing your core logic. Please check out my profile to review my past projects and portfolio: https://www.freelancer.com/u/Hammadhassan21 I am an independent developer and available to start immediately. Ping me to discuss the details and get started. Thanks.

Interesting project, I will build all 11 screens in FlutterFlow with custom Dart code actions, Firebase Auth (email, Apple, Google), Firestore structure for check-ins and streaks, RevenueCat subscription gating, and OneSignal push notifications — delivering a clean, commented project with GitHub repo handoff. For streak tracking, I will ensure the Cloud Function uses server-side timestamps — not device time — to prevent users from manipulating streaks by changing their phone clock. Questions: 1) Are daily check-ins time-zone-aware, or tied to UTC? 2) Do milestone increments map to specific screens or feature groups? Looking forward to talking through the details. Kamran

@Herculesz

Red Fox Hi I can build your men’s mental performance app in FlutterFlow exactly from your finalized PRD, 11 screen specs, brand system, content, and user flow documentation. My focus would be clean FlutterFlow execution with custom Dart/Flutter actions, Firebase Auth, Firestore real-time data, Cloud Functions, RevenueCat subscriptions, OneSignal notifications, and Firebase Analytics. The main technical challenge is making streak tracking, gated premium access, and behavior-triggered notifications reliable while keeping the FlutterFlow project clean and maintainable. I would solve this with a clear Firestore structure, server-authoritative Cloud Functions for streak logic, tested RevenueCat entitlement checks, and structured OneSignal trigger handling. I am comfortable working independently, following milestone-based reviews, giving async updates, and recording short walkthroughs for completed work. I can also prepare the GitHub handoff, comment custom code actions clearly, and support App Store and Google Play submission steps from the completed FlutterFlow build. My focus would be accurate build execution, stable integrations, and a production-ready app that matches your approved design and product logic. Thanks, Hercules

I see you're looking for a FlutterFlow developer for a mobile app with Firebase and RevenueCat integration. It’s great that you’re focusing on both iOS and Android platforms, which is essential for reaching a wider audience. With around 10 years of experience in mobile app development, I'm confident in my ability to deliver a smooth user experience across both platforms. I understand your main goal is to create an engaging app with 11 screens, ensuring that communication remains clear and effective throughout the process. 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 make this project a success together. Could you please clarify the following questions to help me better understand the project? Q1: Can you provide more details about the functionality of the 11 screens? Q2: What specific features do you envision using Firebase for, and how do you plan to implement RevenueCat? Q3: Are there any particular design guidelines or existing styles you want to follow for the app?

@codefusion53

Red Fox Hi, Your project stands out because the scope is exceptionally well-defined. With the PRD, design system, user flows, content, and backend services already decided, the focus can remain where it should be: high-quality execution. I have experience building Flutter and Firebase applications with authentication, subscriptions, push notifications, analytics, and production deployments. I'm comfortable working inside FlutterFlow, including custom Dart code actions when native FlutterFlow functionality is not sufficient. Firebase Auth, Firestore, Cloud Functions, RevenueCat, OneSignal, and analytics integrations are all familiar parts of my workflow. I appreciate your milestone-based process and daily communication structure. Building in small reviewable increments reduces risk and ensures every screen, workflow, and subscription flow matches the PRD before moving forward. Particular attention would be given to server-authoritative streak tracking, subscription entitlement handling, notification reliability, and clean Firestore architecture to support future phases. I am available to start immediately and can work directly with your specifications without requiring additional product definition. Best, Justin
