iTunes vs. Google Play
Which one is better?
Similarites
They are both very well known and widely used. One is for Apple users and the other is for Android users.
Differences
Both Apple and Google launched their mobile app stores in 2008 — Apple in July and Google in October, giving iOS a three month lead time on Android. Despite having similar birthdays, the iTunes App Store pulled out to an early lead in terms of app availability. It took the iTunes app store 11 months to cross the 50,000 threshold, a milestone Google Play wouldn’t hit until April 2010, a full year and a half later.
Prices
The prices on the apps are pretty much the same.
