I’m building a lightweight age-calculator app exclusively for Android. The core requirement is that once the user enters their birth date, the app keeps updating their exact age in real time—years, months, days, down to seconds—without needing to tap any refresh button. Please handle the full development cycle: clean UI/UX, accurate time calculations that respect leap years and time zones, and smooth performance on recent Android versions. If you feel an optional birthday picker or even fun add-ons like zodiac info would improve usability, let me know, but the live age updates are non-negotiable. Deliverable: a fully functional APK plus readable, well-commented source code (Kotlin or Java) ready for submission to the Play Store.

Hello, You need a **lightweight Android age-calculator app** where the user enters their birth date once and the app **updates their exact age in real time (years, months, days, hours, minutes, seconds)** without any manual refresh. I can develop this using **Kotlin with a clean, minimal UI** and implement a precise time calculation system that correctly handles **leap years, time zones, and continuous real-time updates**. The app will include a **date picker for easy birth date selection**, smooth performance on recent Android versions, and well-structured, commented code so it’s easy to maintain or expand later. Optional enhancements like **zodiac info or next birthday countdown** can also be added without affecting performance. Deliverables will include the **fully functional APK and complete source code ready for Play Store submission**, along with brief guidance for publishing. Quick question: would you like the app to **save the user’s birth date locally so the age keeps updating automatically when the app is reopened**?
