Apple has announced the list of its all time popular iOS apps for iPhone and iPad – both free and paid. The list was released after the App store hit 25 billion downloads.

Can you guess what they are? Yes, you can. Most of these apps are games, the ones you have downloaded and played addictively. While the rest are some commonly used social networking apps like Facebook and Skype.

The factor that made iOS apps so popular is that they are cheaper than Android apps. According to a report by Canalys, top 100 paid Android apps cost $374, while top 100 paid iPhone apps cost only $147. There is also another reason behind Apple’s success - most of the paid iOS apps are priced at a reasonable $0.99, making these apps easily affordable.
