I already have a detailed blueprint that spells out every formula and screen of my personal work app; what I need now is the actual Android build. The sole purpose of the app is to run those calculations locally—no databases, cloud calls, or extra features—then present the results in the layout I have drawn. I’d like the code written in Python so I can extend it later. If you normally package Python for Android with Kivy, Chaquopy, BeeWare, or a similar toolchain, that fits perfectly. Clear, well-commented code and a straightforward build process are important because I’ll be maintaining the project myself after delivery. Deliverables • Install-ready APK that runs on recent Android phones and tablets • Complete, editable source code plus any build scripts or Gradle files • README showing build steps and a quick test that proves the calculations return the exact values in my spec I’ll supply the full formula sheet, UI mock-ups, and a set of sample inputs/outputs as soon as we start. The job is done once I can install the APK, enter those samples, and see the expected numbers appear on screen without errors.
