The battle of OS giants is getting interesting by the day. Presumably, Apple's App Store dominance has been leading the market for the past few years. Surprisingly, for the first time in 2017, Android users are spending more money than their iOS counterparts.

Marketwatch.com has posted details of Android's projected triumph over the celebrated Apple OS. According to the info gathered by the network, things are going well for the both companies. However, users are spending more money on apps and subscriptions on the Play Store.

According to data, Android users will spend $41 billion in total apps, compared to Apple's $41 billion. App Annie, which focuses on data related to mobile app ecosystems tabulated the projection.

Last year the App Store had a large lead over Android's Play Store when it racked up $34 billion. The Google app store only had a total of $27 billion of app and subscription sales in the same period.

But despite the numbers, Apple will still have the most dominant single app store. Alphabet's Google Play has several third-party apps that run on the Android OS.

For instance, devices like the Kindle tablet run on Android but has its own modified app store for users. App Annie's projection for the Google Play is right around $21 billion and $20 billion for the other apps.

According to TechCrunch, App Annie's senior vice president might have an explanation for the Android surge. Danielle Levitas pointed out that Android devices far outnumber iOS devices by a 5 to 1 global ratio.

Levitas believes that there is so much room for improvement for the Android system. However, he also said that the Apple App Store will remain the most lucrative OS store in the next five years.

Moreover, Apple's monolithic approach might be the biggest factor for their consistent sales. Interestingly, as more people invest in Android devices, there might come a time when it will be on top of the OS market shares.
