Apple revealed some of the most exciting changes to iOS in years at WWDC recently. The introduction of thousands of new APIs, extensibility, widgets, HomeKit, HealthKit, CloudKit and much more have left app developers with a lot to consider about the future of their apps. So with an unprecedented number of possibilities of where apps could go, what is this going to all mean for the average user? It’s all very well to read the descriptions of the new technology, but what will it look like in apps you care about? The team at Two Toasters (which makes products like the Webby Award-winning Birchbox iPhone app) mocked up how some of the most popular apps might take advantage of iOS 8 when it launches later this year.

Amazon’s 1-click purchase with Touch ID

Touch ID (Amazon)

Touch ID — the fingerprint reader on the iPhone — has always been a neat, but slightly gimmicky feature. Now with iOS 8 developers will finally be able take advantage of Touch ID authentication in their own apps. For example, Amazon could take implement Touch ID API to make purchasing more streamlined and secure instead of asking a user for credit card verification. It’s easy to imagine that shopping, banking and other apps dealing with sensitive information will also likely want to take advantage of Touch ID to provide protection without hampering usability.
