Success: whenever a command or task completes successfully you will hear this sound.

Failure: when a task fails or an error occurs you will hear this sound.

Attention: a request for your attention is made with this sound.

Input: entry screen input is acknowledged by this sound.

Access Denied: you will hear this sound if an access sequence fails.

Access Granted: successful completion of an access sequence sounds like this sound.

Not Valid: if a command cannot be performed or is unavailable, or a text entry is invalid, you will hear this sound.

Data Available For Download: when new data (vaults and messages sent to you by others) is available for download you will hear this sound.

Sounds can be switched off in the 'Admin' screen.

Appearance   top
iOS 7 - love it or hate it - relaxed the need for ultra-slick and sophisticated user interface elements in various sizes. This is quite liberating to a developer who doesn't have the tools or skills to render life-like elements. It also helps in creating a consistent interface.

I decided to use this newfound freedom to simply draw elements on index cards, take pictures (with an iPhone, of course,) then format the elements in the Preview app. This procedure frees up a lot of time better spent (methinks) on functionality and debugging.
