If you don't already know, Qi trawls the print and online media for game and app reviews from respected sources like Macworld, TiPb, 148Apps, and GameSpot. A unique Qi formula is then applied to each site and publication to establish a definitive Qi score for the app or game. Top 5 recommendation lists, news round-ups, and regular industry analysis complement the dynamic Qi charts. Qi has its own Twitter feed, too, @qualityindex.

With its intuitive single-finger control system, scintillating soundtrack, and near-limitless replayability potential, this is one escape you'll want to make over and over again.
Orbiting the lower regions of the Top 10, meanwhile, is the feathery follow-up that's taking Android by storm: Angry Birds Space.
Strapping the established bird-flinging formula to a rocket and launching it into the stars, Rovio's interstellar sequel adds some compelling gravity mechanics, and an all-new bird made entirely of ice.
Pocket Gamer's reviewer found Angry Birds Space a worthy addition to the series, saying "it manages to recapture the destructive thrill that made the original so essential".
Another Angry Birds purchase in T-minus 5...4...
