Apple has released iOS 7, which means developers have begun releasing iOS 7-optimised apps.

Not wanting to look irrelevant or outdated, Flipboard, eBay, Yahoo and other mobile apps have updated with new user-interface designs that appear more flat. Apple also posted a notice for developers on Tuesday, alerting them to start submitting 64-bit-compatible App Store apps.
