Every week, Gamasutra rounds up the top-grossing iPhone, iPod Touch and iPad applications, as current that day in the iTunes App Store. This week's U.S. revenue charts see Top Girl and Happy Park earning top iPhone sales, while Lego Harry Potter and Shadow Vanguard HD emerge as big sellers on the iPad.

These charts allow end users to see who is making the most money on the App Store that day. It differs significantly from the Top 10 Games chart, which is ranked by sales, and therefore is dominated by lower-priced titles that sell more copies.

Data comes courtesy of Apple's public sales information. All titles in the App Store's "Games" category are considered in chart rankings.

This week's top-grossing iPhone titles are:

1. Tap Pet Hotel (Free)
2. Zynga Poker (Free)
3. Top Girl (Free)
4. Angry Birds ($0.99)
5. Tap Zoo (Free)
6. Texas Poker (Free)
7. Smurfs' Village (Free)
8. Tiny Tower (Free)
9. Fashion Story (Free)
10. Happy Park (Free)

Microtransation-supported titles dominate the iPhone's top-grossing sales chart, with this week seeing Crowdstar's Top Girl joining Pocket Gems' Tap Pet Hotel and Zynga Poker in the platform's top three.

Infinidy Corp's Happy Park returns to the top ten after a recent update, as NimbleBit's Tiny Tower maintains a chart presence in the face of competition from longtime favorites Smurfs' Village and Tap Zoo.
