Apple 's App Store is the only place for iPhone and iPad users to download and use apps, which means it's the only way for developers to get their third-party apps out to Apple consumers. This has caused concern to many developers, and the UK's Competition and Markets Authority's (CMA) is getting involved. Apple is under investigation as its terms and conditions on the App Store have been labeled as unfair and could break competition law. While no decision has been made as of yet if Apple is breaking the law, the results could lead to some major changes on the App Store.
