Fantasy fulfiller Square Enix has adapted Song Summoner: The Unsung Heroes for iPhone and iPod Touch.
We reviewed the regular-iPod original last September, but since then Square Enix has added touch-screen controls and new characters and scenarios. Will they justify the £5.99 asking price? There's a demo to help you make your mind up.
Also on the App Store is Namco Bandai's Ace Combat Xi: Skies of Incursion, which only costs £2.99 for the next five days. It's got "HD quality graphics!"
