As of the fourth quarter of 2019, there are 2.57 million Android apps and 1.84 million apps for iOS. In 2018, the total revenue from mobile app downloads, advertising, and in-app purchases was $365.2 billion. In 2023, this number is projected to reach $935.2, which denotes a considerable jump by almost 2.7X. But given how mobile internet penetration has exceeded half of the world’s population, these statistics are not surprising at all. Consumers are still downloading mobile apps, even though the global uninstall rate after 30 days is 28%. That shows that although mobile apps are popular, it is not enough to just launch one anymore. Instead, the app’s success depends on how well it is developed, marketed, and updated. And in this article, we will focus on iOS app development.
iOS apps take the cake
Speaking of iOS, the Apple Store is the second-leading mobile app store in the world, which will comprise 5 million apps – including both iPhone and iPad – by the end of 2020. Besides, last year, Apple’s App Store was #1 in the US, garnering 3X more sales than Google Play. Ever since the tech giant opened the doors of its App Store, the number of developers from around the world trying to cash in on this lucrative opportunity has increased. According to Payscale, iOS developers with an experience of five years make $100K on average in the US, as of 2020. Whereas, in the UK, they can earn £36,000. In India, the average salary of a fresher is INR 6,56,000. The numbers are proof of the fact that app development can lead to high-paying opportunities – anywhere in the world. So, if you are a developer looking to get a head-start on developing an iOS mobile app or upskilling yourself, these iOS app development resources won’t disappoint.
