Portuguese app store Aptoide has urged EU watchdogs to take action against Google Inc for allegedly blocking rivals in the multi-billion-dollar mobile applications market. Apps are big business for Google and rival Apple Inc, with the market valued as much as $25 billion according to analysts. Googles Play store and Apples App Store are two of the largest in the mobile industry. Aptoide Chief Executive Paulo Trezentos said in a statement Google wasnt playing fair in the mobile app industry and the company had taken its grievance to the EUs competition watchdog.
