The smartphone market has been booming. According to Statista, the revenue generated in 2020 was $409.1 billion. Every sphere of life is now dependent upon these gadgets, and there is no denying that mobile phones have become part of our lives. Today, there are more than 6.4 billion smartphone users in the world.
This trend has increased the possibility of application building even further. However, with the increasing rivalry in this industry, you must ensure that your app design stands out among the thousands of apps available on mobile app markets.
