The notification system on the iPhone mostly gets the job done, but it’s intrusive and gets annoying quickly if you have many system notifications going on at once. Users have been pining for a solution like Google Android’s system of a drop down list of notifications that do not interrupt what you’re doing on the device.
GriP moves to solve this problem by emulating the functionality of Growl on the iPhone. System notifications come up in a transparent alert box that does not keep you from interacting with whatever application you’re using. You can expand the alert box to see alert content, or close the alert box. The developer is also providing information for developers to hook in to the system from their own applications.
Here is a video posted by www.iphoneblog.de showing several of the features of GriP.
It hasn’t been out for long. I can’t find any alternative themes besides what comes built in. I’m hoping to look at the documentation and see if I can make a more finger-friendly theme soon.
But as I said, I’m very excited about this. I hope Apple is paying attention. You can find GriP in Cydia if you have Jailbroken your iPhone or Touch.
