The program's interface isn't particularly beautiful, but I didn't find that bothersome. Since inserting a signature requires moving between Mail and iSignature, you want that to happen as quickly as possible--eye candy would just slow things down. Despite the minimalist interface, though, it would be nice if AL Software could make the app work a tad faster. I found that my signatures appeared somewhere between two to three seconds after launching the app--not super speedy but still usable. The app also seems very solid; I've experienced no crashes with it so far.

iSignature is still very much a 1.0 product, though it's my hope that AL Software will continue to improve upon a serviceable first effort. I plan to keep it on my home screen right above the Mail icon. I just have to remember to be extra careful to select the right signature when I create my messages; I really can't risk signing an important business message with "Love ya, Snookums. -Your Big B."

iSignature is compatible with any iPhone or iPod touch running the iPhone 2.x software update.
