App developer Jared Sinclair loves Apple, but he really does not like its new operating system, iOS 7. He finds parts of its design “unjustifiable.” Sinclair has worked on apps like Whisper and Riposte.

As Sinclair rightfully points out, the only way for a touch screen work well is to make it completely obvious which parts of the screen you’re supposed to touch.

In iOS 7, Apple uses a lot of implied borders around icons, but it doesn’t actually give you a button to press. Instead, it uses colors, symbols or words to distinguish touchable links, which are confusing.

Here’s an example Sinclair provides:

“Color alone simply cannot be the way to identify a button. You don’t touch a color. You touch an area,” Sinclair writes. “To activate a button, you must touch a spot inside of its boundary. Text floating in the middle of vast whitespace doesn’t define a boundary. Only borders define boundaries.”
