The app itself is simple as can be, it’s sole purpose is to allow you to add some fancy glyphs to your email, text message, notes, etc.
To install the app you’ll need to open up Mobile Safari, navigate to http://mrgan.com/gb/ and follow the onscreen instructions.
To use the app, simply tap the icon to open, choose the glyph you’d like to use by tap and hold, select copy, and then you can paste it into whichever app you’re wanting to add the glyph to, eg. Mail, Notes, Simplenote, Tweetie, Facebook, WordPress, etc.
One of the best functions that web apps add to the iPhone is that you don’t ever need to update them as you’re essentially viewing a website each time you launch the app. The downside of course is that you’re accessing a website so it doesn’t work unless you’ve got some form of connectivity.
Anyway go check it out, it’s free!
