Twitter's Periscope claims App of the Year in Apple's 2015 App Store picks

Periscope, the Twitter-owned live streaming app, was chosen as the overall favorite among Apple editors. Close behind were Lightricks' Enlight photo editor, and Robinhood, an app for free stock trading.

Under a separate Games category, puzzler Lara Croft GO came in first, followed by Fallout Shelter and Mr Jump.

Automated action tool Workflow was selected as the "most innovative" general app, while the sound-based horror title Dark Echo was picked for most innovative game. Two 3D Touch-enabled apps, Instagram and Warhammer 40,000: Freeblade, were promoted as the best entries for the iPhone 6s. Both have been featured prominently in Apple press events.

In raw download terms, Heads Up! was the top paid app, while the most popular free one was Trivia Crack. The top grossing app however was Supercell's "freemium" game Clash of Clans — though technically free to play, gamers can get the upper hand by buying in-game currency with real money.
