I’m looking for a straightforward Android app whose core purpose is to ease my task: quick, reliable data entry of numerical information. In addition to the mobile build, I also need a small companion application so I can review, edit, and export the same records on my computer. Key requirements • Clean, minimal input screens dedicated to numerical data entry • Local storage with the option to export or sync (CSV, SQLite, or any lightweight format you recommend) • Companion desktop or web-based viewer/editor that reads the same dataset • Basic search, edit, and delete functions for existing entries • Intuitive UI—no training manuals needed Tech stack is flexible; standard Android SDK with Kotlin or Java is fine, and the companion app can be a lightweight desktop build (Electron, .NET, JavaFX) or a small web interface—whichever you’re fastest with. Please include: 1. A brief outline of your proposed stack and timeline 2. Any similar apps you’ve shipped before 3. Your plan for basic testing and hand-off The goal is a functional prototype we can iterate on, not a polished enterprise solution, so focus on solid core features and clean code.
