This is as the description says optimized for the iPhone, and not at all much of an app for the iPad. It looks clunky and works clunky. It rarely gets the screen orientation right at first, and it does not refresh the messages properly without going back and forth between inbox and listing.

Really needed to make some phone calls but only had Internet available. This app did the job and did it well. And it's easy to use.

This app looks nice and fundamentally works OK. However: (1) it's an iPhone app and not an iPad app. Expect the usual 1x/2x sizing game -- and only works in portrait mode! I almost never use my iPad in the portrait orientation -- it falls out of my keyboard too easily that way. And (2) When I first tried to use it, I could not get it to work. Silly me, I was clicking on the "Sign In" button. Instead, I had to "hit enter" in the password field. Not sure what the purpose of the "Sign In" button or whatever it was labeled (maybe be "Log In). One would expect a polished app. This is not it.

This little app packs so much easy to use value. So many cool calculators including a regular number cruncher.
