How was the development and implementation of this application carried out?

Development and deployment of an Android application typically involves several stages:

1. Planning and Design — defining functionality, creating interface mockups.
2. Development — writing code in Java or Kotlin using Android SDK and Android Studio.
3. Testing — verifying functionality on emulators and real devices.
4. Building and Packaging — creating APK or AAB files.
5. Deployment — publishing the app on Google Play or distributing it through other means.

During development, architectural patterns (e.g., MVVM) are used, along with libraries to simplify working with UI, network, databases, etc. Deployment may include integration with CI/CD systems for automating builds and tests.

Example: development using Android Studio, Kotlin, Jetpack Compose for UI, Room for local database, and Retrofit for network requests.
