Hello, I have reviewed your requirements and can handle the complete IoT hardware and app integration, including an offline device, digital display, programmed calculations, and a simple app to show the input data and calculated output. I have 10+ years of experience working on connected applications and backend/device integrations, and I would approach this with a practical design that keeps the hardware reliable offline while keeping the app ready for future connectivity or feature expansion. I can also help define the hardware components and communication method based on the calculation logic and expected device usage. WORKING FLOW: Hardware Planning → Select the suitable microcontroller, display, power setup, and required components based on your inputs and calculations. Firmware Development → Program the device to process inputs, perform calculations, and display the required output reliably without internet access. App Development → Build a clean mobile interface to enter/view data and display the calculations received from the hardware. Hardware-App Integration → Establish reliable communication between the device and app and verify that values remain accurate during different test scenarios. Testing & Handover → Test the complete device workflow, fix integration issues, and provide the source code with basic setup documentation. Thanks, Invoke Tech

It sounds like you're looking for a solution that combines hardware and software to create a digital display that performs those calculations based on inputs. And I can design and develop the hardware device to meet your specifications, making sure it operates offline as required. For the app, I’ll create a user-friendly interface that effectively displays the input data and, you know, results from the calculations. I can have everything ready for you to test first, so you can see it in action before making any payment or awarding the project. This way, you can be sure it meets your expectations without any risk on your end. But if there are any tweaks needed, I'm totally on it. I’m ready to start immediately and can complete this project for 56299 INR, which is a fair price for the work involved. Rajavel - IoT Developer specializing in hardware and app integration.

Hi, The key part here is making the device work independently without depending on internet or cloud services. I’d first define the input and calculation logic, then select the suitable microcontroller and digital display based on the required accuracy and hardware inputs. The calculation would run directly on the device, with the result shown on the display. The mobile app can connect locally to the hardware (Bluetooth/Wi-Fi) and show the same input data, calculations and device status in a simple interface. I’d build and test the hardware prototype first, then connect the app once the device flow is stable. I can share relevant IoT and app work and explain the approach based on your exact calculation requirements. What type of inputs will the hardware receive, and do you already have a preferred connectivity method such as Bluetooth? Regards Abhisehk
