Built With 🔩

• Room Persistance Library - This library provides an abstraction over SQLite and makes it a lot simpler to save and fetch data from a device's database.
• Coroutines - Coroutines are used to perform two or more tasks parallely or asynchronously. They are very useful when you need to load data from cloud into your app.
• NDK - Native Development Kit, enables you to write some part of your app's code in C language which makes it difficult to recover the encryption keys or API keys on reverse engineering.
