With Chip you’ll be able to customize the banner changing the background color (single color or gradients), adding a gloss effect, adding a border and changing the text color and font. Chip also allows you to edit the notification sound using iOS default tones or your ringtones from iTunes.
Last but not least, Chip brings the possibility to use custom animations.
And if that’s not enough, you can have specific preferences for every app (if no app-specific preferences exist, global ones will be used).
That is useful, for example, to recognize which app got a notification basing on the sound.
Preferences are located in Settings.app>Notifications.
