South Korean music star Psy’s popularity continues to spread, even on the top free iPhone apps list. Information search engine Wolfram Alpha’s Gangnam’s Style app has vaulted up the charts since its release last week, landing at the No. 3 spot on iPhone. In anticipation of Disney’s animated film Wreck it Ralph, the official game app for the movie Fix-it Felix Jr. has climbed its way to the No. 7 position on iPhone and No. 12 position on the top free iPad apps chart. Solar system app Solar Walk reaped the benefits of a one-day sale that moved the game from $0.99 to free, which pushed the app to the No. 15 spot on iPhone and No. 5 spot on iPad.
Halfbrick Studios’ Jetpack Joyride has made its way from iOS to Android just a few weeks ago and it has already cracked the top 25 on the top free Android apps list at the No. 19 spot.
