Android Calculator App
Budget: ₹100 – ₹400 INR
I would like a clean, reliable calculator built specifically for Android. The goal is a lightweight APK that installs quickly, opens instantly, and performs every core arithmetic function without lag or crashing on current Android versions.
Here is what I need delivered:
• Fully functional calculator interface coded in Java or Kotlin, adhering to current Android Studio best-practices.
• Material-style UI with clear buttons, large display field, and responsive layouts that look tidy on phones and tablets.
• Smooth handling of user input, real-time result updates, and graceful error checks (division by zero, malformed entries, etc.).
• A signed, ready-to-publish APK plus all project source files and build instructions so I can compile future updates myself.
If you can add smart touches—theme switching, dark mode, haptic feedback—let me know, but solid core functionality is the priority.
