Make sure to release the memory when it is not needed anymore to avoid memory leaks.

Code optimization is also a big deal. Write clean, efficient code. Avoid unnecessary calculations and loops. The efficiency of your code directly impacts the performance of the app. Reduce complexity, and streamline your algorithms. Code optimization involves writing efficient code. This leads to faster execution times and better performance. This goes hand in hand with efficient algorithms. Use the right data structures. The choice of data structures can significantly impact performance. For example, using an array instead of a linked list can speed up access times. Remember, every line of code can impact performance, so it pays to be careful. The right data structures for the right jobs is a key point to optimize. Finally, don't forget about network requests. Minimize the number of requests and optimize the data transfer. Compress images and data to reduce the amount of data transferred over the network. Caching is another great trick. Cache data locally to avoid making repeated network requests. With a bit of optimization, your app will be flying high! So go forth, and make your app a performance powerhouse!
