Basic Calculator App Development
Budget: $10 – $40 USD
I need a straightforward calculator designed exclusively for Android phones. The focus is on speed, accuracy, and a clean, minimalistic look—no gradients, ads, or flashy extras—just a crisp interface that lets users add, subtract, multiply, and divide the moment the app launches.
Here’s what I expect:
• A lightweight Android Studio project (Java or Kotlin) with clear, well-commented code.
• An APK ready for direct installation on current Android devices.
• A tidy, one-screen layout that scales neatly on common resolutions, guided by Material Design basics but stripped down to the essentials—buttons, display, and nothing more.
• Basic error handling (e.g., division by zero, input overflow) so the app never crashes.
• A brief readme explaining build steps and how to tweak colours or fonts should I want minor visual changes later.
Keep the architecture simple; I’d like to open the project and immediately understand what’s happening. As soon as the final APK and source zip are delivered and I verify all four core operations work flawlessly, the job is done.
