Hi there, This is an interesting project and I can help you build both the smart bottle system and the connected mobile app. I understand the goal is to create a reliable setup where the bottle tracks water intake and syncs smoothly with an app that reminds users to stay hydrated. I can handle the full flow—from IoT integration (sensor + data tracking) to a clean mobile app for Android and iOS with real-time sync and notifications. The focus will be on accuracy, stable connectivity, and a simple user experience so users can easily track their intake without friction. What I’ll cover: IoT setup for tracking water intake Mobile app with real-time sync Hydration reminders & notifications Clean, user-friendly UI Scalable structure for future features I’ve worked on similar app + integration projects and understand how to keep both hardware and software working reliably together. I can start right away and discuss the best approach for your use case. Thanks Sachin

Hi there, I have read your project requirement. You need a smart water bottle integrated with a mobile app that tracks water intake, provides hydration reminders, and is scalable for future feature enhancements. We can develop a complete IoT solution including sensor-based water intake tracking (using flow/weight sensors), Bluetooth/Wi-Fi connectivity via ESP32, and a cross-platform mobile app (Flutter) with real-time sync, reminders, and a clean UI/UX. The system will be designed modularly so future features like health insights, gamification, and wearable integrations can be easily added. Questions: ========= Do you prefer Bluetooth (BLE) or Wi-Fi for bottle-to-app connectivity? Should the app include user profiles and daily hydration goals? Do you need cloud sync or only local device tracking initially? Are there any design references for the bottle hardware or app UI? Best Regards, Srashtasoft Team

Hello, Scope note: a full smart bottle with custom hardware plus iOS and Android apps sits above this budget. Within £20-250 I will build the Flutter companion app (iOS + Android) to pair with a BLE bottle — intake tracking, graphs, reminders — with BLE stubbed against a mock bottle until hardware is ready. Hardware (ESP32 or Nordic nRF52 with a weight sensor) I can plan for a later phase when budget allows. Questions: 1) Any bottle hardware design or vendor in mind? 2) Target market — general consumer or health/fitness niche? Looking forward to talking through the details. Faizan

I can help you define and develop your smart water bottle from concept to a working, testable prototype. The focus will be on accurate water-intake tracking, reliable connectivity, and an intuitive companion app experience that users actually engage with daily. I’ve worked on IoT and wearable-style products that combine embedded hardware, sensors, Bluetooth connectivity, and mobile apps. That includes designing low-power firmware, selecting suitable sensors, and ensuring data syncs cleanly to iOS/Android for notifications and long-term tracking. My approach would be to clarify requirements, choose appropriate sensors and microcontroller, design the firmware and mobile app APIs, then iterate through prototype, testing, and refinement. I’ll also document architecture and future scaling options. I would love to chat more about your project! Regards
