After installing the app on your iPhone or iPad, signing up for an account is a snap. Type in your user name, add your email address and password, and activate the account. You can also post some information about yourself, and include a picture. If you want to add your friends, toss in your phone number.
One feature of Peach is its use of Magic Words. When you post a Magic Word on "your space," you click on the bubble that pops up to activate it. For example, type the word "here" and your current location is added to a post. Or you can type "Shout" and what you type is written in big letters to simulate screaming. Type the word "song," and Peach will use your phone's microphone to give you the name of the tune that is playing within earshot. You can check out all of the Magic Words, at least the ones that work now, by clicking on the slideshow. New ones will be added over time.
Obviously these are early days for Peach, so we really can't tell you that this is going to be the next big thing. The developer says that it pays attention to user feedback, so if you have suggestions for the app don't hesitate to write them.
