The Android-based Ideal Weight Information and Calculation Application has several features, namely calculating body mass index, tips, eating schedule, and exercise. There is an explanation for each of these features. The Android-based Ideal Weight Information and Calculation Application was created using the Java programming language, JDK, Android-based XML and Android Studio with SDK.
