Android Live Calculator App

Job ID: 40329453

Budget: ₹600 – ₹1,500 INR

I’m commissioning a compact calculator for Android that must feel instantaneous and stay free for users. As soon as a number is typed, the result should update live. The scope of functions covers three clear areas: everyday arithmetic, a full set of scientific operations (trig, log, power, etc.), and an on-device graph plotter that can render a single-variable function quickly.

The interface needs to keep to a minimalist style—plain background, calm accent colour, flat icons, and a single screen flow wherever practical. No in-app purchases; instead place one unobtrusive banner ad (AdMob or similar) pinned to the footer.

Please build in Android Studio; Kotlin is preferred but clean Java is fine. Ship me:

• Release-ready APK
• Well-commented source in a Gradle project
• A brief README explaining build steps and how to swap the ad unit ID

This is a ₹1,500 starter assignment. Deliver high-quality, lightweight code and I’ll line up regular follow-on apps for you.
