I’d like a simple yet polished mobile calculator app written in Python. It must do the everyday basics—addition, subtraction, multiplication and division—and also offer a graph-plotting screen where I can enter a function such as y = 2x + 3 and see the curve render instantly. Please build it as a true mobile application that runs on both Android and iOS. Kivy, BeeWare or any other Python-friendly framework is fine so long as I can open the project in a standard Python 3 environment, read the code and continue learning from it. What I expect to receive • Complete, well-commented source code • A brief README with setup, build and deployment steps • Debug or release builds that I can sideload for quick testing (APK for Android; TestFlight, IPA or simulator build for iOS) Clean, readable code and a straightforward UI are more important than elaborate styling. If you already have ideas for making the graphing interface intuitive—pinch-zoom, pan, light/dark mode—feel free to suggest them.

Hi there, I understand you are looking for a polished, lightweight mobile calculator application built in Python that supports both basic arithmetic and real-time graph plotting. I can certainly help you build this using a Python-friendly framework like Kivy or BeeWare I prioritize clean, maintainable code over complex UI styling. I am comfortable working within standard Python 3 environments and can implement intuitive features like touch-based panning and zooming for the graphing screen. To clarify the scope: would you like the graphing feature to support advanced functions (like quadratic or trigonometric expressions) from the start, or should I focus on ensuring a robust foundation for linear equations first?

Python Mobile Calculator & Graphing App Hi there, I see you need a clean, cross-platform mobile calculator with instant graph-plotting capabilities, built entirely in Python. I have direct experience developing custom scientific calculators in Python, meaning the core logic for mathematical operations and equation parsing is something I am already highly proficient in. To meet your requirements for both Android and iOS, I recommend using the Kivy framework (or BeeWare, depending on your UI preference). Kivy is particularly strong for handling touch interfaces like the pinch-zoom and panning features you mentioned for the graphing screen. I will ensure the UI remains straightforward and intuitive, prioritizing function over elaborate styling. The final delivery will include heavily commented, highly readable Python 3 source code, the compiled test builds (APK for Android), and a detailed README with step-by-step instructions so you can easily deploy, read, and learn from the code yourself. To ensure the graph renders exactly how you envision it, do you want the plotting screen to support trigonometric functions (like sin, cos, tan), or should we stick strictly to linear and polynomial equations for this first version? Let me know so we can discuss the next steps! Best regards, Safia K.
