-# 📱 Aplikasi Kalkulator BMI
+Tip Time - Solution Code
+=================================

-**Dibuat oleh:**  
-👨‍💻 **Rafi Fattan Fitriardi**  
-🆔 **NIM: 202310715002**  
-🏫 **Pemrograman Perangkat Bergerak - F5A5**
+Solution code for the [Android Basics with Compose](https://developer.android.com/courses/android-basics-compose/course): Tip Time app.

---

-## 📖 Deskripsi Aplikasi
-Aplikasi **Kalkulator BMI (Body Mass Index)** ini dibuat sebagai proyek akhir mata kuliah **Pemrograman Perangkat Bergerak**.  
-Tujuan utama aplikasi ini adalah membantu pengguna menghitung **Indeks Massa Tubuh (BMI)** berdasarkan **berat badan (kg)** dan **tinggi badan (cm)** untuk mengetahui apakah berat badan tergolong **kurang, ideal, berlebih, atau obesitas**.
+Introduction
+------------
+The Tip Time app contains various UI elements for calculating a tip,
+teaching about user input, and State in Compose.

-Aplikasi ini memiliki **dua halaman utama**:
-1. **Halaman Biodata Pengembang** – menampilkan informasi pembuat aplikasi (nama, NIM, kelas, dan foto), serta tombol **“MULAI”** untuk berpindah ke laman utama.
-2. **Halaman Utama (Kalkulator BMI)** – tempat pengguna menginput berat dan tinggi badan, menekan tombol **“Hitung BMI”**, lalu melihat hasil nilai BMI beserta kategori dan saran kesehatannya.

---
+Pre-requisites
+--------------
+* Experience with Kotlin syntax.
+* How to create and run a project in Android Studio.

-## ⚙️ Fitur Utama
- Input berat dan tinggi badan secara interaktif.  
- Perhitungan otomatis nilai BMI.  
- Tampilan kategori hasil (Kurus, Normal, Gemuk, Obesitas).  
- Antarmuka sederhana dan responsif.  
- Navigasi antarhalaman menggunakan tombol **MULAI** dari halaman biodata.
-
---
-
-## 🧩 Teknologi yang Digunakan
- **Android Studio (Kotlin)**  
- **XML Layouts** untuk desain antarmuka  
- **Intent** untuk navigasi antar activity  
- **Drawable XML** untuk gradasi dan tema warna aplikasi

-## 🧠 Kontribusi & Kredit
-Aplikasi ini dikembangkan dengan bantuan **ChatGPT (OpenAI)** dalam pembuatan kode, desain antarmuka, dan penyusunan dokumentasi.  
-Semua logika, pengujian, dan penyempurnaan dilakukan secara mandiri oleh pengembang.
