Hello, I am engaged in application development on Flutter for iOS/Android/Web, I have commercial experience working in companies, I have experience creating applications independently from scratch (there are proofs in the reviews). I also create custom backend on Python with subsequent deployment on servers. I am available for work, I can start right now. I am ready to consult on all questions.

Hello.
The project looks very interesting and quite complex. Essentially, you are planning a platform at the intersection of wearables, health analytics, and AI, where data from the device is transformed into personal recommendations and further interaction with a specialist.
We have worked with similar technical tasks — specifically with BLE devices, synchronization of biometric data, mobile health applications, and integration of AI assistants. The main difficulty of such systems is usually not in visualizing graphs, but in the stable operation of Bluetooth synchronization, background data collection, proper storage of time-series metrics, and further AI processing.
From a technical point of view, the MVP can be built approximately like this:
— mobile application (Flutter for quick cross-platform MVP)
— BLE integration with the device SDK and stable data synchronization
— backend API (Node.js or Python FastAPI)
— user database PostgreSQL + time-series storage for biometrics
— Health Score analytics module
— AI assistant based on OpenAI / Claude
— chat user ↔ specialist
— push notifications
— protocol and execution tracking module
— product catalog with Apple Pay / Google Pay
From your description, it is clear that you are correctly laying out the structure of the MVP:
first integration with the device → data collection → analytics → AI → interaction with the specialist.
To more accurately assess the scope, a few points need clarification:
— does the ring manufacturer provide a full BLE SDK or just protocol documentation?
— is background synchronization planned when the app is closed?
— should the AI assistant work only as an explanation of graphs, or also generate recommendations based on Health Score?
— will there be a web panel for specialists where they can see user data and assign protocols?
— is the marketplace an internal catalog or integration with a third-party e-commerce?
Such products are usually built in stages. A realistic MVP (BLE + cabinet + basic analytics + AI chat) takes about 3–4 months of team work.
We can help not only with development but also with the architecture of the platform, so that the system scales properly when thousands of users and large volumes of biometric data appear.
I would be happy to discuss the details and take a look at the device SDK.

Roman, this is not just a mobile application. It is hardware + real-time + medical data + AI + commerce in one product.
90% of performers underestimate the BLE part. This is where MVPs most often "fail": unstable connection, background synchronization, packet loss, battery issues.
If done correctly, a realistic plan is as follows:
Timeline: 4–5 months to a stable MVP
Budget: $45,000 – $70,000
The team that is truly needed:
• Senior Mobile (Flutter/React Native + BLE experience)
• Backend (FastAPI/Node + time-series database)
• QA with real BLE testing on devices
• UI/UX with experience in health products
• partial involvement of an AI engineer for assistant logic
We can launch a Lean version in 2–3 months (BLE + Dashboard + basic AI summary) with a budget starting from $25,000, and add the Marketplace in the second phase.
I am not suggesting "to make an application."
I am suggesting to build the right architecture from the start, so that in 6 months you won't have to rewrite everything from scratch.
If interested, I am ready to outline the BLE risks and architectural solution for your hardware separately.

Good day! I have reviewed your project on the development of an MVP Health-Tech application with great interest. My 5 years of experience in creating cross-platform mobile solutions on Flutter for iOS and Android, combined with deep skills in Backend development (Python/TypeScript) for data integration with BLE devices and implementation of AI logic, allows me to effectively accomplish the tasks at hand. Additionally, my competencies in interface design will ensure the convenience and intuitiveness of the application. I am ready for a detailed discussion of the project.

Hello.
I am a mobile engineer, engaged in the development and launch of products for startups, from idea to working MVP. I work with the React Native and Node.js stack, and I have commercial experience in native development. I have experience integrating BLE in fitness applications (collecting and synchronizing heart rate data), as well as working with OpenAI and Claude API for implementing AI chats and data processing. I have skills in creating neat minimalist designs for premium-level products.
I understand how to quickly assemble the first working version of a product, test a hypothesis, and bring it to a stable state without unnecessary complications.
I am ready to discuss the details.

Good day.
I have reviewed the description of the MVP. I have experience in developing mobile applications using React Native with BLE integration (GATT, working with characteristics, background synchronization, reconnection) and connecting manufacturer SDKs.
I have integrated the OpenAI API for chats and analytics, implementing AI logic + manual consultant. I work with FastAPI / PostgreSQL, building APIs for mobile health projects, including time-series data.
I understand the specifics of working with biometrics, security, and the stability of BLE connections.
I am ready to discuss the details and stages of implementation.
