Project description:
"I need a lean, reliable Android application that lets users enter numerical values and then returns counts based on a custom set of rules I will provide. These rules go beyond a simple tally, so you will be implementing an in-app algorithm that applies conditional logic to every entry before updating the running total.

Here is what I’m expecting:
• A clean Android interface (Java or Kotlin is fine) with a single main screen where users can input numbers quickly.
• A background module that applies the special counting logic in real time and displays the updated result instantly.
• Local data persistence so the count is not lost when the app is closed.
• An export or share option (CSV or plain text) for the final count history.

I will share the exact counting rules, edge-case examples, and a simple wireframe once we start. Please make sure your bid includes initial MVP, one round of feedback, and handover of well-commented source code plus build instructions." (client-provided description)
